How to merge PDF files

To merge PDF files, add them to the box above, put them in the order you want and press the Merge button. This tool can also merge PDF and JPG files together, so a phone photo, a scanned certificate and a typed letter end up in one tidy document.

The basic merge runs entirely in your browser, so your files are not uploaded. Options that need more power, such as compressing the result or making scanned text searchable, are clearly marked before you use them.

  1. 1

    Add your files

    Drop PDFs, JPGs or other photos on the box, choose them from your device, or paste them with Ctrl+V. You can keep adding files at any time.

  2. 2

    Put them in order

    Drag the file cards, use the arrow buttons, or sort by name or date. Switch to the Pages view to move single pages, rotate them or remove the ones you do not need.

  3. 3

    Choose options (optional)

    Open Options to add page numbers, compress the merged file to a size such as 1 MB, interleave double-sided scans, or add bookmarks. The defaults work without touching anything.

  4. 4

    Merge and download

    Press Merge PDF, or Ctrl+Enter. Preview the result, download it, or go back and change the order.

Most people are done in under a minute this way: add, check the order, merge. The options are there for the times you need them, not something you have to learn first.

Merge PDF and JPG into one PDF

Yes, you can merge PDF and JPG files into one PDF here, in a single step. Many documents people need to send are a mix: a typed application form as a PDF, plus photos of an Aadhaar card, a marksheet or a receipt taken on a phone. Instead of converting the photos first, add everything together and merge.

The tool accepts JPG and JPEG, PNG, WebP, GIF (the first frame), BMP and iPhone HEIC photos. Multi-page TIFF files and Word, Excel and PowerPoint files are also accepted; they are converted to PDF on our server first, and the tool tells you so before it happens.

Phone photos are turned the right way up automatically. Cameras often save a picture sideways and only mark it as rotated, which is why photos can appear on their side in other tools. Here the rotation is applied before the photo becomes a page, so it comes out upright.

Under Options you can choose how photos become pages. Same as image keeps each photo at its own size, while A4, Letter or Legal place it on a standard page, and Match the first PDF uses the size of your first document. You can also pick portrait or landscape, add a small or large margin, and choose whether the photo fits inside the page or fills it.

A common example is an identity card. Take a photo of the front and the back, add both photos and your application PDF, and merge JPG and PDF into one PDF with the card front, card back and form in order. Transparent PNG images, such as a signature or a logo, are placed on a white page. If you only have photos and no PDF, JPG to PDF and Image to PDF turn them into a PDF on their own.

Merge PDF without watermark, free and with no limit

This is a way to merge PDF without watermark, sign-up or a daily allowance. The merged file contains only your pages: nothing is stamped on them, and there is no account to create and no email to give.

There is no limit on how many files you can merge and no limit on how many times you can use the tool, That is what merge PDF free no limit should really mean: no cap on files, on tasks or on pages. Many free tools stop you after two or three files, or after a few tasks an hour; this one does not.

The real limits come from your device, and we state them plainly. In the browser, each file can be up to 200 MB and all files together up to about 1 GB, which is what a typical phone or laptop can hold in memory comfortably. Options that run on our server, such as compression or OCR, accept up to 100 MB, and Word, Excel and PowerPoint files up to 50 MB.

The reason this can stay free is simple: the basic merge is done by your own browser, so it costs us almost nothing to run. Only the optional server steps use our machines, and those are designed to be quick and to delete your files straight away.

Merge and compress PDF in one step

You can merge and compress a PDF in one step: turn on Compress after merging in Options, and the tool merges your files and then shrinks the result before you download it.

Merged files get large because each part keeps its own images at full size. A few phone photos can add several megabytes each, and scanned pages are pictures too, so a ten-page bundle can easily reach 10 MB or more.

There are two ways to compress. Choose a level (Less, Recommended, Extreme or Lossless) when you just want a smaller file. Choose an exact size, such as Under 500 KB or Under 1 MB, when a website sets a limit; the tool then works to get the merged file under that size while keeping the text sharp.

When it finishes you see both sizes, for example compressed from 8.4 MB to 940 KB, and a note confirming the file is under your limit. If a target is too small to reach while keeping the pages readable, the tool says so honestly and offers to go smaller anyway, rather than handing you an unreadable file without warning.

To merge and compress PDF files this way, the merged file is uploaded to our server once, compressed, sent back and deleted. The option shows an Uploads to our server label so you always know before it happens. If you skip compression, nothing leaves your browser.

Merge PDF under 1 MB (and 500 KB or 200 KB) for portals

Many job, exam and government portals accept only small files, often 1 MB, 500 KB or even 200 KB. To merge PDF under 1MB, open Options, choose Under 1 MB in Compress after merging, and merge as usual. The same works for 500 KB, 200 KB, 2 MB or a custom size.

The table shows typical limits and the option to choose. Always check the exact limit on the form you are filling in, because it can differ from one portal to another.

Typical upload limits and the option to choose
Where you uploadUsual limitChoose in Options
Many job application portals200 KB to 1 MB per documentUnder 500 KB or Under 1 MB
Exam and admission forms100 KB to 500 KBUnder 200 KB or Under 500 KB
Government service portals1 MB to 2 MBUnder 1 MB or Under 2 MB
Email attachmentsOften 20 to 25 MBRecommended level

A few habits make small targets easier. Include only the pages the portal asks for, using the page range on each file or the Pages view. Scan documents in black and white rather than colour where colour is not needed. Photos taken in good light compress far better than dark, noisy ones.

If you only need to shrink a single document rather than combine several, the Compress PDF to 1 MB and Compress PDF to 200 KB tools are built for exactly that.

Merge scanned PDF pages in the right order

To merge scanned PDF pages in the right order, add the scans and arrange them in the Pages view, or let the tool interleave double-sided scans for you.

Many office and home scanners scan one side of a stack at a time. You end up with one file holding pages 1, 3 and 5, and a second file holding the backs, often in reverse order because the stack was turned over: pages 6, 4 and 2. Turn on Double-sided scan: interleave the first two files, keep Second file is in reverse order ticked, and the merged PDF comes out as 1, 2, 3, 4, 5, 6.

Scans taken with a phone are often slightly tilted or unevenly lit. The Straighten and clean scanned pages option evens out the lighting and straightens tilted pages, so the merged scanned PDF looks like it came off a proper scanner.

Scanned pages are pictures, so their text cannot normally be searched or copied. Make text searchable (OCR) reads the text and adds an invisible text layer, while each page looks exactly as it did. You can choose English, Hindi with English, Hindi and Marathi with English, or Marathi with English.

Straightening, cleaning and OCR run on our server, so the merged file is uploaded once for them and deleted afterwards. They are marked with an Uploads to our server label in Options.

Merge PDF with page numbers

To merge PDF with page numbers, open Options, tick Add page numbers and merge. Numbers are added in your browser, so this option needs no upload.

You choose where the numbers go (bottom or top, left, centre or right), the format, the number to start from, the size from 8 to 14 points, the margin and black or grey text. Skip the first page leaves a cover page unnumbered and starts counting from the next page. Numbers are placed the right way up even on pages you have rotated.

Which page-number format to choose
FormatGood for
1Short documents, printouts, books
Page 1Letters and forms that will be printed
1 of NContracts and bundles where missing pages matter
Page 1 of NFormal submissions, legal and audit bundles

Bookmarks make a long merged document easy to move around. By default the tool adds a bookmark for each file, named after the file, and keeps the bookmarks your PDFs already had, so a bundle of five reports opens with a clickable outline. You can also add a table of contents page at the start that lists each file with its page number and links straight to it.

Arrange, rotate and remove pages before you merge

You can arrange, rotate and remove pages before you combine PDF files, without opening another tool.

The Files view shows one card per file with its first page, name, page count and size. Drag cards to reorder them, rotate a whole file, duplicate it, remove it, or type a page range such as 1-3, 5 to use only some of its pages. Sort the list by name or date, or reverse it, in one click.

The Pages view shows every page of every file. Drag a page anywhere, even into the middle of another file, rotate it, delete it, duplicate it or insert a blank page after it. Hold Shift or Ctrl to select several pages and rotate or delete them together, and use the size slider to make thumbnails bigger or smaller.

Every change can be undone with Undo or Ctrl+Z and redone with Ctrl+Y, so you can experiment freely before you combine PDF pages into the final file. For one-file jobs, Split PDF, Organize PDF, Rotate PDF and Delete PDF pages each do a single task.

More options for professional documents

This PDF merger also covers the details that matter for professional and official documents.

Bookmarks and a table of contents

Add a bookmark for each file and keep existing ones, and optionally start the merged PDF with a clickable contents page.

File name footer

Print each page's source file name in a small footer, useful for legal and audit bundles where every page must be traceable.

Blank pages for double-sided printing

Add a blank page after any file with an odd number of pages, so each file starts on a fresh sheet when printed on both sides.

Form fields

Fillable forms keep working. If two forms use the same field name, one is renamed so neither overwrites the other. Or flatten every form so the answers are fixed into the page.

Password-protect the result

Lock the merged PDF with a password using AES-256 encryption, the same protection as Protect PDF. This step runs on our server and is marked as an upload.

Common ways people merge PDF files

Here is how people use this tool for the documents they most often need to send.

Job application bundle

Employers often want one PDF with a CV, a cover letter, degree certificates and an identity proof. Add the CV and letter as PDFs and the certificates as photos or scans, drag them into the order the employer asked for, and merge. If the portal has a 1 MB limit, set Under 1 MB in Options to merge PDF under 1MB and upload in one step.

Exam and admission forms

Admission forms usually ask for marksheets, a photo ID and a caste or income certificate, sometimes in a single file under 200 or 500 KB. Photograph each document in good light, add the photos with the filled-in form, and merge with the matching size limit. Page numbers help the office check that nothing is missing.

Invoices and receipts for accounts

At the end of a month, merge every invoice PDF and every photographed receipt into one file for your accountant or for an expense claim. Sorting by date puts them in order automatically, and a bookmark per file lets the reader jump straight to any invoice.

Scanned contracts and agreements

Long agreements are often scanned front and back separately. Add both scans, turn on the double-sided interleave, and the pages come out in the right order. Straighten and clean scanned pages tidies phone scans, and OCR makes the final contract searchable.

Merge PDF on your phone

You can merge PDF files on an Android phone or an iPhone in the browser, with nothing to install. Open this page, tap Select files and pick PDFs from your files, or photos from your gallery, including iPhone HEIC photos.

Drag the cards with your finger to reorder them; press and hold briefly on a page in the Pages view to pick it up. Tap Merge PDF, then Download, and the merged file is saved to your downloads, ready to attach to an email or upload to a portal.

On a phone, Options work just as on a computer, so you can merge PDF and photos, add page numbers and compress to 1 MB without switching apps.

Is it safe? What happens to your files

By default, your files never leave your device: the merge is done by your own browser, and this page makes no upload when you use the standard options.

Some things cannot be done in a browser, so they run on our server: converting Word, Excel, PowerPoint and TIFF files, unlocking a password-protected PDF, compressing, OCR, cleaning scans and adding a password. Each of these is labelled before you use it.

When a file does go to our server, it travels over an encrypted HTTPS connection, is processed straight away and is deleted as soon as you download the result; anything not collected is deleted automatically within 15 minutes. There is no account, and nothing is shared.

Common problems and fixes

A file asks for a password

Type the password in the box on that file's card and press Unlock. The file is unlocked on our server and the rest of your merge is unaffected. You can also use Unlock PDF first.

A file will not open (damaged)

The card says the PDF looks damaged. Try Repair PDF on that file, then add it again; the other files can still be merged meanwhile.

The merged file is too big

Turn on Compress after merging with a size such as Under 1 MB, or use the Compress it here link that appears when a merged file is over 1 MB.

Photos came out sideways

Photos are turned upright automatically. If one is still wrong, rotate it on its card or in the Pages view before merging.

Pages are in the wrong order

Drag them into place in the Files or Pages view, or use Sort, then merge PDF pages again. For scanned fronts and backs, turn on the double-sided interleave option.

Tips for a clean merged PDF

Check the order before you merge PDF pages into one file. The Pages view shows every page at once, which makes a missing or repeated page easy to spot, especially in a bundle built from many photos.

Name the output file clearly. Change merged.pdf in Options to something like Anita-Sharma-application.pdf, so the person receiving it knows what it is; the name is also stored as the document title.

Keep page sizes consistent when it matters. If a bundle mixes A4 documents, Letter documents and odd-sized photos, Make all pages A4 gives it a uniform look for printing, at the cost of links and form fields on resized pages.

Rotate before you merge, not after. Turning a landscape table or a sideways photo in the Pages view takes one click, and the page numbers you add will still be placed the right way up.

Keep the originals. The merged PDF is a new file; your original files stay untouched on your device, so you can always merge them again in a different order. To edit the words inside the merged document, PDF to Word turns it into an editable Word file.
