PNG to TIFF Converter

Add your PNG pictures to the box above, choose how the TIFF should be made and press the red button. Every picture is turned into a real TIFF file inside your browser, by our own TIFF writer, so nothing is sent to a server and nothing waits in a queue.

You can make one TIFF for each picture, downloaded together as a ZIP when there are several, or put all of them into a single multi-page TIFF. The compression is always lossless, transparency is kept by default, and the DPI you choose is written into the file so the result prints at the size you expect.

This is a png to tiff converter free of the usual catches: there is no account to create, no watermark stamped on your pictures, no daily limit and no paid tier hiding the useful settings. Every option on the page is available to everyone, every time.

It is free because the work happens on your own computer or phone. Our server does not store or process your pictures, so there is nothing for us to charge for per file. You can convert one picture or three hundred, close the tab, come back tomorrow and do it again.

Being free does not mean being basic. You get four lossless compression methods, a horizontal predictor for smaller files, real alpha channel support, a DPI value written into the file, grayscale and 1-bit black and white output, resizing and multi-page TIFF files with your own page order. These are the settings print shops, archives and older programs actually ask about.

Most tools that offer png to tiff online free work by uploading your files to a server, converting them there and sending the result back. That costs time, uses your data allowance and means a copy of your pictures sits on a computer you know nothing about, at least for a while.

Here the page itself is the converter. Once it has loaded, your browser reads each PNG, decodes the pixels and writes the TIFF bytes directly, using code that runs only on your device. You can even disconnect from the internet after the page has opened and the conversion still works.

It runs the same way on Windows, macOS, Linux, ChromeOS, iPhone, iPad and Android, in any up-to-date browser. Very large batches are faster on a desktop computer simply because it has more memory and a faster processor, but the files you get are identical everywhere.

PNG and TIFF are both lossless formats. That means they store every pixel exactly, with no blurring, no blocky artefacts and no colour shifts of the kind you see when a photo is saved as JPG again and again. When a lossless file is converted into another lossless file, nothing needs to be thrown away.

That is exactly what happens here, so a conversion from PNG to TIFF lossless in every setting is possible: LZW, ZIP (Deflate), PackBits and no compression all keep every pixel. If you leave the colour mode on Colour and the size on Original, the TIFF holds precisely the same pixel values as the PNG you started with. Open both in an image editor, compare them pixel by pixel and you will find no difference.

Only three settings change pixels, and only when you choose them: Grayscale removes colour, Black & white reduces each pixel to black or white, and Resize changes the number of pixels. Switching off transparency also changes the pixels in see-through areas, because they are filled with your background colour. Everything else, including the DPI and the compression, leaves the picture itself untouched.

If both formats are lossless, why convert at all? Because TIFF is the format many professional and older systems expect. PNG was designed for the web; TIFF was designed for scanning, printing and publishing, and it has been the standard exchange format in those fields for decades.

Print shops and publishers often ask for TIFF because their layout and prepress software handles it predictably. Archives and libraries keep master copies as TIFF because it is well documented and widely supported by long-term preservation tools. Scanner software, fax systems, document management systems, GIS mapping programs, medical and scientific imaging tools, and many legacy business applications accept TIFF but not PNG.

TIFF can also do a few things PNG cannot. It can hold many pages in one file, which is useful for scanned documents and image sequences. It stores the resolution in a way every print program reads, and it supports 1-bit black and white images that are tiny and sharp for documents and line art.

Libraries, museums, photographers and companies that keep pictures for decades tend to choose TIFF for master copies. The format has been stable for a very long time, its structure is openly documented, and lossless TIFF files can be read by a wide range of programs on every operating system.

PNG is also an open lossless format and is perfectly fine for keeping pictures, so there is no need to convert a collection just for the sake of it. Convert when your archive rules, your digital asset system or the institution you deliver to asks for TIFF, or when you want to keep several related pages together in one multi-page file.

For archive copies, leave the size on Original, the colour mode on Colour and DPI on Keep, so nothing about the picture changes. ZIP with the predictor saves the most space; LZW is the more conservative choice if the files may one day be opened by software you cannot test today.

TIFF, the Tagged Image File Format, was created in the mid-1980s by Aldus, the company behind early desktop publishing software, so that scanners and layout programs could exchange images. Adobe later took over the specification. Its design, a file made of tagged fields that describe the image, is what lets one TIFF hold different compressions, colour modes, resolutions and many pages.

PNG, Portable Network Graphics, arrived in the mid-1990s as a free, patent-free format for the web, with lossless compression and full alpha transparency. It became the standard for screenshots, logos and graphics online. The two formats grew up in different worlds, which is why people so often need to move pictures from one to the other.

Because both formats are open and lossless, moving pictures between them is safe. You can convert a PNG into TIFF today and, if you ever need to, convert that TIFF back into PNG later without losing a single pixel, as long as you did not change the size or the colour mode along the way.

A png to tiff high quality conversion is mostly about not doing harm. Because both formats are lossless, the highest possible quality is simply the original pixels, carried across unchanged. Keep the size on Original, keep the colour mode on Colour and the TIFF will be as good as your PNG, never better and never worse.

Where quality can be lost is in the settings around the conversion. Resizing to a smaller size removes pixels for good. Grayscale throws away colour. Black & white keeps only two tones. Flattening transparency onto a background colour bakes that colour into the edges. Each of these is useful for a particular job, but none of them should be switched on by accident, and none of them is on by default.

If a printer or publisher asks you for a high quality TIFF, they usually mean three things: enough pixels for the print size, a sensible DPI value stored in the file, and lossless compression. The DPI table further down shows how many pixels you need for common print sizes. LZW compression is the safest choice when you do not know what software the recipient uses.

Many PNG files have transparent areas: logos, icons, cut-out product photos, stickers and graphics made to sit on any background. A png to tiff with transparency conversion keeps those areas see-through, and that is what happens here by default.

In Colour mode the option Keep transparency (alpha channel) is switched on. Any PNG with transparent or partly transparent pixels becomes an RGBA TIFF, with red, green and blue channels plus a fourth channel that records how opaque each pixel is. Pictures without any transparency are written as plain RGB TIFF files, so they do not carry an alpha channel they do not need.

The alpha channel is stored as unassociated alpha, the form described in the TIFF standard for transparency masks. Photoshop, GIMP, Affinity Photo and macOS Preview read it and show the transparent areas correctly. Some older or very simple programs ignore the alpha channel and show the hidden colour underneath, often black or white, which is why the option can be turned off.

When you switch it off, transparent areas are filled with a background colour. White is the default, and under More options you can choose any colour you like. Grayscale and Black & white output always fill the background, because those modes do not store an alpha channel.

Every pixel in a normal colour picture has three numbers: how much red, how much green and how much blue. A picture with an alpha channel adds a fourth number for each pixel, from fully transparent to fully opaque. The values in between give soft edges, shadows and glows that blend smoothly into whatever is behind them.

PNG has supported alpha for a long time, which is why it became the standard format for logos and graphics on the web. TIFF supports it too, through what the format calls extra samples. The difference is that not every program that opens TIFF files pays attention to that extra channel, while almost every program that opens PNG files does.

If you are sending a TIFF to someone and you are not sure their software handles transparency, ask them, or send a version with transparency switched off and a white background. If the TIFF is going into Photoshop, GIMP, Affinity or a modern layout program, keeping the alpha channel is the right choice.

Choose All in one multi-page TIFF under Output to combine multiple PNG to one TIFF file. Every picture becomes a page, in the order of the list. Each page shows its number, and the up and down arrows move a page one place earlier or later. Sort by name puts the list in alphabetical order, which is handy when your files are called scan-01, scan-02 and so on.

Multi-page TIFF files are common for scanned documents, faxes, patient records, technical drawings and image sequences. Many document systems and viewers expect one file per document, not one file per page, and a multi-page TIFF does exactly that without converting anything into PDF.

Pages can have different sizes; each one keeps its own width, height and DPI. If any picture in the list has transparency and Keep transparency is on, the alpha channel is used for every page of the file, so the pages are stored consistently. Pictures without transparency simply get a fully opaque alpha channel in that case.

Scanners, phones and screenshot tools often save pages as PNG. Many offices, courts, insurance companies and records systems still expect scanned documents as TIFF, often as one multi-page file per document and often in black and white.

To prepare such a file, add the page pictures, choose All in one multi-page TIFF, check the order and use Sort by name if the files are numbered. Choose Black & white for text, adjust the threshold until thin strokes stay visible without the background turning gray, and pick 300 DPI, or 600 DPI for small print and signatures.

A page of text in 1-bit black and white is usually a small fraction of the size of the same page in colour, so even long documents stay easy to email and store. If a page contains photos or colour stamps that must stay readable, use Grayscale for the whole document instead, because a multi-page TIFF uses the same colour mode for every page.

LZW is selected by default because it is the compression virtually every TIFF reader understands. ZIP (Deflate) uses the same method as PNG itself and usually gives the smallest files, which makes it a good choice when the TIFF is for your own archive or for modern software. PackBits is a very simple method that works well on graphics with large flat areas of one colour, and None stores the raw pixels for programs that cannot decompress anything.

Under More options you will find the horizontal predictor, switched on by default. Before compressing, it stores the difference between each pixel and the one to its left instead of the pixel itself. In photos and smooth gradients those differences are small and repetitive, so LZW and ZIP compress them much better. It is still completely lossless and it is part of the TIFF standard, but a handful of very old readers do not support it; switch it off only if a program shows a striped or noisy picture.

DPI, dots per inch, tells a printer or a layout program how large the picture should be on paper. It does not change the pixels. A picture 3000 pixels wide is 10 inches wide at 300 DPI and 5 inches wide at 600 DPI, with exactly the same detail in both cases.

The DPI setting offers Keep, 72, 150, 300, 600 and Custom. Keep uses the resolution stored in the PNG, or 300 DPI if the PNG has none, which is common for screenshots and graphics exported from web tools. Custom accepts any value from 1 to 4800. Whatever you choose is written into the TIFF's resolution fields, which print and layout programs read.

300 DPI is the standard resolution for photo prints, magazines, brochures and most commercial printing. A png to tiff 300 dpi conversion is the most common request we see from people preparing files for a printer, and it is just one click: choose 300 under DPI.

Remember that the DPI only labels the file. If your PNG is 1200 × 1800 pixels, it will print at 4 × 6 inches at 300 DPI. If you need a bigger print at the same sharpness, you need more pixels, and no setting can invent detail that was never there. Use the table below to check whether your picture is large enough before you send it off.

Choose 600 DPI for line art, text, logos, technical drawings, maps and black and white scans, where crisp edges matter more than in a photo. Many publishers ask for 600 DPI for line art and 1-bit images, and some archives store document scans at that resolution.

A png to tiff 600 dpi file prints at half the size of the same file at 300 DPI, with twice the density of dots in each direction. Combined with the Black & white colour mode, it gives very small, very sharp files for documents and drawings. If your PNG came from a scanner at 600 DPI, leave the setting on Keep and the original value is carried into the TIFF.

When you convert png to tiff for print, the aim is a file the print shop can place and print without asking you questions. Four settings matter: enough pixels for the print size, a DPI value that matches the shop's request (usually 300), lossless compression they can read (LZW is the safe choice) and a background that behaves the way they expect.

That last point is easy to overlook. If your PNG has transparent areas and the shop's software ignores the alpha channel, the transparent parts may print as black or show odd colours along the edges. When in doubt, switch off Keep transparency and choose white, or the colour of the paper, as the background under More options.

Ask the printer whether they need anything special, such as a bleed area, a particular colour profile or CMYK files. Bleed is added in your design program before export. Colour profiles and CMYK are explained in the next section, because this tool deliberately does not pretend to handle them.

Here is the honest answer about png to tiff cmyk conversion: this tool writes RGB TIFF files, not CMYK. Colour mode gives 24-bit RGB, or 32-bit RGBA when transparency is kept. It does not produce CMYK TIFF files, and we would rather say so plainly than let you find out at the print shop.

CMYK stands for cyan, magenta, yellow and key (black), the four inks used in most commercial printing. Screens mix light in red, green and blue; presses mix ink. Turning RGB into CMYK is not a simple formula: it depends on the paper, the inks and the press, which is why it is done with an ICC colour profile chosen for the job.

A PNG file is always RGB, or grayscale; the PNG format has no way to store CMYK at all. So any CMYK version of your picture has to be created by a colour-managed conversion somewhere. Many print shops are happy to receive RGB TIFF files and convert them with their own profile, matched to their press and paper, which often gives better results than a conversion made without that knowledge.

If your printer insists on a CMYK TIFF, convert the RGB TIFF made here in Photoshop (Image, Mode, CMYK Color), in Affinity Photo (Document, Convert Format / ICC Profile) or in GIMP with a CMYK plugin, using the profile your printer recommends. Or simply ask the printer which profile to use, or whether they will do the conversion for you; many will.

Before you send a TIFF to a printer, run through a short check. Is the pixel size large enough for the print size at the DPI the printer asked for? Is the DPI written correctly, which you can confirm in Preview, Photoshop or GIMP? Is the compression one the printer can read, with LZW as the safe default?

Then check the background and colour. If the picture has transparent areas, does the printer want them kept or filled with white? Does the printer accept RGB, or do they need CMYK, in which case convert in a colour-managed program as described above? Finally, open the TIFF yourself once, to make sure it looks the way you expect before it goes to press.

Colour mode decides how each pixel is stored. Colour writes 24-bit RGB, 8 bits for each of red, green and blue, or 32-bit RGBA when the picture has transparency and Keep transparency is on. This is the mode for photos, artwork and anything where colour matters.

Grayscale writes 8-bit gray, 256 shades from black to white. It makes files about a third of the size of colour ones and suits black and white photos, scans of printed pages and medical or scientific images that are gray to begin with.

Black & white writes 1-bit images: every pixel is either black or white, decided by a threshold you can adjust. Pixels lighter than the threshold become white and darker ones become black. This is the classic format for faxes, document scans, signatures, line art and stamps, and it gives by far the smallest files, especially at 600 DPI.

The TIFF files made here use 8 bits for each colour channel, the same as almost every PNG. Colour gives 24-bit RGB or 32-bit RGBA, Grayscale gives 8-bit gray and Black & white gives 1-bit. Browsers decode pictures at 8 bits per channel, so a rare 16-bit PNG, made by some scientific or high-end photo software, is converted at 8 bits per channel; for those files, export the TIFF directly from the program that made them.

Each TIFF keeps the file name of the original picture with a .tif ending, so photo.png becomes photo.tif. The .tif and .tiff endings mean exactly the same thing, and you can rename a file from one to the other if a system insists on a particular ending.

Under More options, Resize lets you change the pixel size while converting. Original keeps every pixel. Longest side sets the bigger side of each picture to a number of pixels you type, so portrait and landscape pictures are handled alike. Percent scales every picture by the same amount.

Pictures are never made bigger by Longest side; if a picture is already smaller than the number you type, it keeps its size. Shrinking a picture reduces the file size of the TIFF and is useful when a system has a size limit, but the removed pixels are gone for good, so keep your original PNG. For more control over sizes, crops and presets, use Resize Image first and convert afterwards.

Add up to 300 pictures at once, each up to 100 MB. With One TIFF per picture, each file is converted with the same settings and named after the original, with a .tif ending. A single result downloads straight away; several results come together in one ZIP file so you do not have to click through hundreds of downloads.

With All in one multi-page TIFF the same batch becomes one file with one page per picture. Conversion runs picture by picture with a progress bar, and you can stop it at any time. Large pictures use a lot of memory while they are being converted, so on a phone it is better to convert very big batches in a few smaller groups.

The page is set up for PNG, but the same converter also reads JPG, WebP, GIF, BMP and AVIF pictures. You can mix them in one batch, or combine them in one multi-page TIFF. For GIF files the first frame is used. JPG files have no transparency, so they always become RGB TIFF files.

Converting a JPG into TIFF keeps the JPG's pixels exactly as they are, but it cannot undo the compression that JPG applied when it was saved. For a page focused on photos, see JPG to TIFF. To go the other way, TIFF to JPG makes small files for sharing, and TIFF to PDF turns TIFF pages into a PDF document.

Designers often receive logos, icons and cut-out product shots as PNG and need TIFF for a print layout, a packaging file or a client's brand library. With Keep transparency on, the soft edges and shadows of the PNG are carried into the TIFF's alpha channel, so the artwork still sits cleanly on any background when it is placed in a layout.

Screenshots, charts, diagrams and digital paintings convert just as well. Graphics with large flat areas of colour compress very well with ZIP or LZW, so their TIFF versions stay small. If a chart or diagram will be printed in a book or report, set the DPI to 300 and check its print size in the table above.

On Windows, TIFF files open in the Photos app and in the older Windows Photo Viewer. Multi-page TIFF files are shown page by page in some viewers but only the first page in others; if you need to check every page, open the file in a program such as GIMP or IrfanView, or convert it with TIFF to PDF and look at the PDF.

On a Mac, Preview opens TIFF files, shows every page of a multi-page TIFF in the sidebar and displays transparency correctly. Quick Look (press the space bar on a file in Finder) gives a fast preview. On iPhone and iPad, the Files app shows TIFF files, and Photos can import them.

Web browsers are a different story: Safari displays TIFF, but Chrome, Edge and Firefox do not show TIFF files in a tab and will download them instead. That is normal and does not mean the file is broken. TIFF is a working format for printing and archiving; for the web, keep the PNG or use PNG to JPG.

The converter works on phones and tablets as well as computers. On an iPhone or iPad, add pictures from Photos or Files; finished TIFF files and ZIPs are saved to the Files app, usually in Downloads. On Android they land in the Downloads folder. A desktop computer handles the largest batches fastest, because it has more memory to hold big pictures while they are being written.

To check a result, open it in Preview on a Mac, in the Photos app on Windows, or in Photoshop, GIMP or Affinity. Look at the image size and resolution in the program's image information: the pixel size should match the original, unless you resized, and the resolution should show the DPI you chose.

TIFF files are often larger than the PNG they came from, especially with no compression, so think about how you will send them. Several TIFF files are already packed into one ZIP by the converter, which keeps them together and is easy to attach or upload to a file transfer service.

Many email services limit attachments to around 20 to 25 MB. If a batch is bigger, choose ZIP (Deflate) compression with the predictor on, send the files in smaller groups, or share them through cloud storage. If the person only needs to view or print the pictures, a PDF made with TIFF to PDF is often easier for them to open on any device.

Some specialist programs read TIFF but not PNG. Mapping and GIS software has long used TIFF for scanned maps, overlays and imagery. Scientific, laboratory and medical imaging tools commonly import and export TIFF, often in grayscale. Older document management, fax and records systems frequently accept TIFF and PDF only.

For these programs, plain and simple files work best. Choose LZW or no compression, switch off the predictor if the program is old, switch off transparency, and choose Grayscale if the images are gray anyway. Note that this tool writes ordinary TIFF images: it does not add map coordinates, as GeoTIFF files do, or medical metadata, so those still come from the software that created the original data.

TIFF is not always the right answer. For websites, online shops, social media, email and messaging, PNG or JPG is better: every browser shows them, while TIFF files are downloaded instead of displayed in most browsers. If nobody has asked you for TIFF, the PNG you already have is usually the simpler file to share.

Keep PNG for web graphics, app icons, screenshots for documentation and anything shown on screen. Use TIFF for printing, publishing, scanning, archiving and software that requires it. And if what you really need is a document to send or print, PNG to PDF may suit the recipient better than a TIFF.

Your pictures are not uploaded. The page loads once, and from then on every step, reading the PNG, decoding it, compressing the pixels and building the TIFF, happens inside your browser on your own device. No copy of your pictures reaches our server, so there is nothing for us to store, view, share or delete.

This matters for scans of ID documents, contracts, medical images, unreleased product photos and anything else you would rather keep to yourself. It also means the tool keeps working when your connection is slow, and the speed depends on your device rather than on a busy server.

Your browser decodes each picture into raw pixels. Our TIFF writer, a small program that runs in the page, then arranges those pixels in strips, applies the compression and predictor you chose, and writes the TIFF header with the image size, the colour mode, the resolution and, when needed, the alpha channel description.

For a multi-page TIFF the writer chains one image directory per page in a single file, in the order of your list. For one TIFF per picture, each file is written separately and the results are packed into a ZIP. The finished files are created as downloads by your browser; nothing is sent anywhere.

Keep LZW as compression unless you know the recipient's software reads ZIP; it is the most widely supported lossless choice. For your own archive, ZIP with the predictor usually saves the most space.

Check the pixel size against the DPI table before sending a file to print. If a picture is too small for the print size you want, ask for a larger original rather than raising the DPI.

When you do not know whether the recipient's software handles transparency, send a version with transparency switched off and a white background, and keep the transparent version for yourself. To cut a subject out of its background first, use Remove Background, which gives you a transparent PNG to convert.

Name scanned pages with numbers before adding them, such as page-01 and page-02, then use Sort by name to put a multi-page TIFF in the right order in one click.

Keep your original PNG files. The TIFF is lossless, but if you resized or used grayscale or black and white, the original is the only full-quality copy.
