JPG to ICO Converter

Add your picture to the box above, pick the icon sizes and press the red button. A few moments later you have a real .ico file that holds every size you chose, ready for a website, a Windows folder, a shortcut or a desktop program.

JPG photos and logos work, and so do PNG, WebP, GIF and BMP pictures. Everything happens inside your browser on your own device, so your picture is never uploaded, there is no sign-up and there is no watermark on the icon. As a JPG to ICO converter free for everyone, it has no paid version and no hidden limit on the sizes or options you can use.

An icon is not just a small picture. Windows, browsers and many programs expect a special file with the .ico extension that can carry several sizes of the same image inside it, so the system can pick the right one for each place. A JPG photo cannot do that, which is why a renamed .jpg file usually shows a blank or broken icon.

To create a proper JPG to icon file, this tool draws your picture onto a square at every size you choose, then packs all of those sizes into one .ico file with the correct header and directory, exactly the way Windows reads them. You get one file that looks right in the taskbar, in Explorer, on the desktop and in a browser tab.

Renaming photo.jpg to photo.ico does not make an icon. The file still contains JPG data, and Windows, which reads the first bytes of the file to find the icon directory, finds none and shows a blank page symbol or refuses the file in the Change Icon window.

A real icon needs the ICO header, a directory entry for every size and square images of exactly those sizes. That is what this converter writes. The result is a genuine .ico file that every version of Windows since Vista, every browser and most icon tools open without complaint.

Most icon converters ask you to upload your picture to a server, wait in a queue and download the result again. Here the conversion is done by your own browser, so it starts at once, works with a slow connection once the page has loaded and keeps your logo or photo private.

If you were looking for a JPG to ICO online free tool that does not limit you, this is it: no account, no daily cap, no watermark and no advert stamped on the icon. It runs the same on Windows, Mac, Linux, Chromebook, Android and iPhone, in any up-to-date browser.

A good icon file holds the same picture at several sizes. Windows shows 16 pixels in the corner of a window, 32 in lists, 48 for medium icons and 256 for large and extra large icons. When a size is missing, Windows has to stretch or shrink another one on the fly, and the result looks soft or jagged.

That is why this converter puts JPG to ICO multiple sizes into a single file instead of making one file per size. Choose a preset or switch to Custom and click any size on or off: 16, 20, 24, 32, 40, 48, 64, 72, 96, 128 and 256 pixels are all available, and every size you select ends up in the same .ico file.

If the icon is for a website only, the Favicon preset with 16, 32 and 48 pixels is enough, and the favicon pack adds the larger PNG files phones need. A small favicon.ico also loads faster, which matters a little on every page view.

If the icon is for anything on Windows, a folder, a shortcut, a program or a drive, choose the Windows icon preset. It covers the sizes Explorer, the taskbar and the Start menu draw, including 256 for large views. Pick All sizes when the icon will be seen on many different screens or by programs that look for unusual sizes, and Custom when a guide or build tool lists exact sizes.

Windows does not always draw icons at their nominal size. On a laptop set to 150% scaling, a 32 pixel spot becomes 48 real pixels, and a 16 pixel spot becomes 24. If the icon file only has 16 and 32, Windows enlarges them and they look fuzzy; if it also has 24 and 48, Windows uses those directly and the icon stays sharp.

That is the reason the All sizes preset includes in-between sizes such as 20, 40 and 72. They take up little space in the file and make sure there is a close match for every common display scale, from an old office monitor to a 4K laptop screen.

The 256 × 256 size is the one Windows uses for large and extra large icons in Explorer and on high resolution screens. If an icon file stops at 48 or 64 pixels, Windows enlarges that small version and the icon looks blurry exactly where people see it biggest.

A JPG to ICO 256x256 icon solves that. The Windows icon and All sizes presets both include 256 × 256, and in Custom you can add it with one click. It is also the upper limit of the format: an .ico file cannot hold anything larger, so 256 is the right top size for any Windows icon.

For the clearest result, start from a picture that is at least 256 pixels wide and high. A smaller picture can still be used, but the tool will not invent detail that is not there, so the large size will look as soft as the original.

Shrinking a big photo straight down to 16 pixels in one step tends to lose thin lines and leave the icon muddy. This tool instead halves the picture step by step, each time with smooth filtering, until it reaches the target size. That keeps edges clean and lets the 16 and 32 pixel versions stay readable.

For JPG to ICO high quality results, also keep the picture simple: a bold logo, a single letter or a face fills the small square much better than a wide landscape. Use Crop to fill to zoom in on the important part, and a little padding when the subject touches the edges.

Each size is made from your original picture, not from the size before it, so the 256 pixel version keeps all the detail your JPG had. With the Modern format the sizes are stored without any further loss, so there is no second round of JPG blur inside the icon.

At 16 × 16 pixels an icon has only 256 dots in total, fewer than the letters in a short sentence. Professional icon designers often draw this size by hand for that reason. A converter cannot redraw your picture, but it can give the small sizes the cleanest possible start.

You can help by choosing a picture whose main shape is large and simple, cropping tightly, using strong contrast and avoiding text. Compare the 16 and 32 pixel previews as you change the fit and padding: often a small change, such as Crop to fill instead of Fit, makes the difference between a blob and a recognisable symbol.

Before you download anything, the live preview shows your icon at 16, 32, 48 and 256 pixels, side by side. Every change to the fit, background, shape or padding appears at once, so you can see whether a detail disappears at the smallest size and adjust before you save.

The small previews are drawn at their real pixel size rather than enlarged, which is the honest way to judge an icon. If the 16 pixel version looks crowded, try Crop to fill, more padding or a simpler picture.

The JPG format has no transparency at all: every pixel is solid, which is why logos saved as JPG usually sit on a white box. An icon with a white square around it looks out of place on a dark taskbar or a coloured desktop.

To make a JPG to ICO transparent icon, set Background to Transparent and tick Make the white background transparent. The tool turns white and near-white pixels clear and uses a soft edge, so the outline of your logo blends smoothly instead of keeping a thin white fringe. The tolerance slider sets how close to white a pixel must be to disappear.

Raise the tolerance a little if a pale halo remains; lower it if light parts of your logo start to vanish. This works well for logos and drawings on a plain white background. For a photo with a busy background, cut out the subject first with Remove Background and then use the PNG result here.

Windows can use a light or a dark theme, and browsers show tabs in light and dark colours too. A transparent icon sits directly on those colours, so a black logo can vanish on a dark taskbar and a white one on a light tab.

To be safe on both, give a very dark or very light logo either a solid background or a shape such as Rounded or Circle with a contrasting colour. Transparent works well for colourful icons with a clear outline, which stand out on any theme.

The background fills any area of the square that your picture does not cover, and the corners when you choose a rounded or circle shape. Transparent leaves those areas clear, White fills them with white, and Colour lets you pick any colour, for example your brand colour behind a logo.

A solid background is a good choice when the icon will sit on many different backgrounds and must always stand out, or when an old program cannot show transparency. Transparent suits modern Windows, browsers and macOS, where the icon should look cut out.

Icons are square, but most photos are not. Fit keeps the whole picture and places it in the middle of the square, so nothing is cut off; the empty sides take the background you chose. Crop to fill covers the whole square and trims the longer side, which makes the subject bigger and is usually the right choice for faces and photos.

Stretch forces the picture into the square and changes its proportions, which is rarely wanted for photos but can be handy for artwork that is nearly square already. To choose exactly which part of a photo becomes the icon, crop it first with Crop Image and then convert the cropped file.

Choose Square for a classic Windows icon that fills the whole area, Rounded for soft corners like many modern app icons, or Circle for a round badge, a profile picture or a coin-style logo. With Rounded and Circle the corners outside the shape become transparent, so the icon keeps its shape on any background.

Circle works especially well for faces and avatars. If you want a round picture rather than an icon file, Circle Crop makes a round PNG instead.

Padding adds an empty margin of 0 to 30 percent around your picture inside the square. Many icons look better with a little breathing room, because Windows places icons close together and an image that touches every edge can look cramped or cut off.

About 5 to 10 percent suits most logos. Use more for circle icons, so the corners of a square logo do not get clipped by the round edge, and none at all for photos that should fill the whole icon.

Most logos are wider than they are tall, with a symbol on the left and a name on the right. In a small square the name becomes a grey smudge, so crop the logo down to its symbol or first letter before converting. Crop Image lets you select that square part quickly.

Logos saved as JPG almost always sit on white. Turn on the white background option to make the area around the symbol clear, check the edges in the 48 and 256 pixel previews, and add a little padding so the symbol does not touch the frame. The result looks like an icon that was designed as one.

A face makes a friendly icon for a personal folder, a contact or a profile, but only if it fills the square. Choose Crop to fill so the face is large, and use Circle for the familiar round avatar look with transparent corners.

A portrait taken in front of a busy background loses clarity at small sizes, because the background competes with the face. A plain wall behind the person works better. If the photo has a busy background, Remove Background can clear it first, and the cut-out PNG then converts here with its transparency kept.

Small icons are seen at a glance, so contrast matters more than detail. A dark shape on a light background, or a light shape on a dark one, reads clearly at 16 pixels; two similar shades of the same colour merge into one. Lines thinner than one pixel at the small sizes simply disappear.

If your picture is pale, a coloured background often helps: pick Colour under Background and choose a strong brand colour, then compare the 16 pixel preview with the transparent version and keep the one you can recognise faster.

Inside an .ico file each size can be stored in one of two ways. Modern stores each size as a PNG image, which is small, keeps full transparency and is what Windows Vista and later, every current browser and macOS expect. It is the default and the right choice for almost everyone.

Classic stores each size as a 32-bit BMP image with an alpha channel and the extra AND mask that older software reads. Pick it when an old program, a game mod tool or an icon editor refuses the modern file or shows it as blank. Classic files are larger, especially with the 256 pixel size, but they open in nearly everything.

A favicon is the small icon in a browser tab, in bookmarks and in search results on phones. Browsers still look for a file called favicon.ico in the root of a website, and an .ico file with 16, 32 and 48 pixels covers every desktop browser. Choose the Favicon preset for that.

Going from JPG to favicon properly takes more than one file, because phones and home screens want PNG icons too. Tick Favicon pack under More options and the download becomes a ZIP with favicon.ico, favicon-16x16.png, favicon-32x32.png, apple-touch-icon.png at 180 pixels, android-chrome-192x192.png, android-chrome-512x512.png, a site.webmanifest file and your own .ico file. The apple touch icon always gets a solid background, because iPhones fill transparent areas with black.

Upload the files to the root folder of your site and paste these tags into the head section of every page. The Copy HTML tags button copies them for you after the pack is made.

Browsers keep favicons in their cache for a long time, so after replacing one you may need to open the site in a private window or clear the cache to see the new icon. Keep the favicon simple: at 16 pixels there is room for one letter or one bold shape, not a full logo with text.

If you already have a logo as PNG with transparency, the Favicon Generator and PNG to ICO pages do the same job from that file.

A custom folder icon makes a busy drive much easier to scan: a photo of a person on their folder, a logo on a client folder, a game cover on a game folder. Windows only accepts .ico files for this, and a JPG to ICO for Windows folder icon needs the sizes Explorer uses, from 16 up to 256 pixels. The Windows icon preset includes them all.

After the download, keep the .ico file somewhere it will stay, such as a folder named Icons in your Documents. If you move or delete the icon file later, the folder goes back to the plain yellow icon.

Windows does not copy an icon into a folder or shortcut; it remembers the path to the .ico file. Keep all your icons in one permanent folder, for example Documents\Icons, before you assign them, and do not rename or move that folder afterwards.

Keep the original JPG next to the icon as well. If you later want a different background, shape or size, you can make the icon again in a few seconds instead of searching for the picture.

Shortcuts on the desktop and in the Start menu can have their own icon too. Right-click the shortcut, choose Properties, open the Shortcut tab and click Change Icon, then Browse to your .ico file. This is a quick way to give a website shortcut, a script or a portable program a recognisable picture.

Drives, too, can show a custom icon through an autorun.inf file on USB sticks, and many launchers and docks accept .ico files for their entries. In each case a file with several sizes looks crisp at every size the program chooses to draw.

Developers need an .ico file for Windows programs, installers and Electron or other desktop apps, where the icon is built into the .exe. Build tools usually ask for one file with 16, 24, 32, 48 and 256 pixels at least; the Windows icon preset gives exactly that, and All sizes adds 20, 40, 64, 72, 96 and 128 for every display scale.

Keep the Modern format for current build tools. If an older resource editor or compiler complains that the icon is invalid, convert again with Classic, which writes the bitmap format those tools were made for.

Gamers use icons for game folders, launcher entries, server lists and mods. Many mod tools and older game editors were written before PNG icons existed and only read bitmap icons, which is why the Classic format is available.

A cover art JPG makes a good game icon when cropped to the main character or logo. Choose Crop to fill, Rounded for a modern tile look, and include 256 × 256 so the icon looks sharp in large icon views.

macOS opens .ico files in Preview, and browsers on Mac use favicon.ico like everywhere else, so the favicon pack works the same for Mac visitors. Mac apps and folders use another icon format, but for a custom folder icon on a Mac you can copy any picture, open Get Info on the folder, select the small icon at the top and paste.

On Linux, desktop environments mostly use PNG files for app icons, while browsers, Wine programs and many cross-platform apps still read .ico. The PNG files in the favicon pack are useful there too.

Add up to 100 pictures at once and each one becomes its own .ico file with the same settings: the same sizes, fit, background, shape and padding. Several icons download together as one ZIP.

This is handy for a set of folder icons, a series of game or app icons, or the logos of several clients. Because the work happens on your device, a batch takes only as long as your computer needs, not the time to upload and download every file.

This page is made for JPG and JPEG photos and logos, but PNG, WebP, GIF and BMP pictures work just the same. A PNG or WebP with transparency keeps it, so you do not need the white background option for those.

To convert other picture types, Image to ICO accepts more formats, and to turn an existing icon back into a normal picture, use ICO to PNG or ICO to JPG.

The pictures that make the clearest icons have one strong subject, high contrast and few small details: a logo mark, an initial, a simple symbol or a close-up of a face. Bright colours on a plain background stay readable even at 16 pixels.

Wide photos, group pictures and text-heavy logos lose most of their detail when squeezed into a tiny square. If your logo has a symbol and a company name, use only the symbol for the icon. When in doubt, look at the 16 pixel preview: if you can still tell what it is, the icon works.

A detailed photo becomes hard to read at 16 pixels, whatever converter you use, because there are only 256 dots to show it. Simple logos and faces work much better. The tool also does not upscale a tiny picture into more detail: a 64 pixel picture will look soft at 256.

An .ico file cannot hold anything larger than 256 × 256 pixels; that is a rule of the format itself. For larger app icons on phones and websites, the favicon pack adds 180, 192 and 512 pixel PNG files next to the .ico.

ICO is the icon format Windows has used since its early versions. One file starts with a short header, then a directory that lists every image inside with its width, height and position, then the images themselves. Windows reads the directory and picks the size that fits each place most closely.

Today most icons store each size as a PNG image, while older icons use bitmaps with a mask. Browsers read both, which is why favicon.ico has stayed the standard name for website icons for more than twenty years.

Newer formats such as PNG and SVG are used for many icons today, yet ICO remains the only format Windows accepts for folders, shortcuts and program files, and favicon.ico is still the file every browser asks for first. That is why an .ico file stays useful even when you also have PNG versions.

Because one .ico can carry many sizes, it also saves you from keeping and naming a separate file for every size. One file per icon is easier to share, back up and assign.

Your pictures are not uploaded. Reading the JPG, drawing every size, removing the white background, packing the .ico file and building the ZIP all happen in your browser, on your own device. Close the page and nothing remains on any server.

That matters for unpublished logos, client work and personal photos. It also means the page keeps working for converting once it has loaded, even on a slow or unstable connection.

Your browser opens the picture and places it on a square canvas using your fit, padding, background and shape. For each chosen size the picture is reduced in halving steps with smooth filtering, so small sizes stay sharp.

If you asked for a transparent white background, pixels close to white are made clear with a soft edge set by the tolerance. Each size is then encoded as PNG or as a 32-bit bitmap with a mask, and all of them are written into one .ico file with a directory that Windows, browsers and macOS can read.

Start from the largest, cleanest version of your picture you have.

Use the Windows icon preset for folders, shortcuts and programs, and Favicon for websites.

Check the 16 pixel preview before you download.

Add 5 to 10 percent padding for logos so they do not touch the edges.

Keep the icon file in a permanent place before you assign it to a folder.

Choose Classic only when an older program needs it.

Use Crop to fill for faces and Fit for logos that must stay whole.

Test a transparent icon on both a light and a dark background.

Look at all four previews and make sure the subject is clear at 16 pixels.

Check the edges of a transparent icon for a white fringe in the 256 pixel preview.

For Windows, make sure 16, 32, 48 and 256 are selected.

For a website, upload every file from the favicon pack and paste the tags.

Keep a copy of the original picture so you can make the icon again with other settings.
