How to merge PDF files into one

  1. 1

    Add your files

    Click Choose PDFs or drop the documents onto the page. You can select several files at once and add more later.

  2. 2

    Set the order

    Use the arrows next to a file name to move it up or down, and remove any file you do not need. The pages of the merged document follow the list exactly.

  3. 3

    Click Merge PDFs

    The pages are copied into a new document without being turned into images, so the text can still be selected and searched.

  4. 4

    Check and download

    The tool opens the finished file and compares the page count, page sizes and text with the originals. Only then does the Download PDF button appear, and the file is named after the first document in the list.

What goes into the merged file

Everything on the pages comes across: text, images, vector graphics and fonts. Bookmarks, form fields, digital signatures, attachments and custom page numbers belong to the source document as a whole, so they are not carried over. If a file contains any of these, you see a notice next to its name before merging.

When merging PDFs into one file helps

An accountant wants a month of invoices in one attachment, a job or university application form may accept only one file, and an office wants a form together with all its supporting documents. Instead of sending a dozen separate files, merge them into one document with the pages in the order the reader expects.

Want to merge a PDF with a JPG, a phone photo or a Word file? Save them as PDF first: turn JPG photos into PDF with JPG to PDF, iPhone HEIC photos and other formats with Images to PDF, and save a Word document as PDF directly in Word.

Mixed page sizes and the size of the result

Each page keeps its own size and rotation. If you merge an A4 or Letter document with a photo-shaped scan or a landscape presentation, the result contains pages of different sizes, exactly as in the originals. Turn an upside-down scan the right way up first with Rotate PDF.

The merged file is roughly as large as all the source files together. With many scans you can easily go over an email attachment limit, which is 25 MB for a personal Gmail account. If that happens, shrink the result with Compress PDF, where you can choose a target size such as 5 MB.

Privacy

Merging happens in a browser tab on your device. The files never reach a server, so you can safely merge contracts, bank statements or medical records. Your originals stay unchanged, and nothing is left behind once you close the tab.

FAQ

Are my PDF files uploaded to a server?
No. Everything happens in your browser tab: the files are read, merged and checked on your device. Their contents are never sent to a server, and nothing is kept once you close the tab.

How many files can I merge at once?
There is no fixed limit, so you can merge two files or fifty. The real limit is your browser's memory, not the tool: ordinary documents of a few hundred pages work even on a phone, but merge scans of hundreds of MB in smaller batches and then merge the results.

Can I merge password-protected PDFs?
Not directly. The tool rejects any encrypted file, including one that opens without a password and only blocks printing or copying. Remove the protection with Unlock PDF first, and after merging you can protect the finished document again with Password protect PDF.

Can I merge a Word document or photos with a PDF?
This tool merges PDF files only. Turn JPG, PNG or HEIC photos and TIFF scans into PDF with Images to PDF first, and save Word documents as PDF directly in Word. Then merge all the files here in one go.

Will the text stay searchable?
Yes, if it was searchable in the source files. Pages are copied together with their fonts and are not turned into images, so you can still select and search text across the whole merged document, and screen readers can still read it.

How do I know nothing is missing from the merged file?
Before you download it, the tool opens the finished file and compares it with the source files: page count, page dimensions and selectable text. If anything does not match, the result is not offered for download and your source files stay untouched.

Are bookmarks and form fields kept?
No. Bookmarks, form fields, digital signatures, attachments and custom page numbers belong to the source document as a whole, so they are not carried into the merged file. The page content stays complete, and if a file contains any of these, the tool shows a notice next to its name before merging.

What will the merged file be called?
The result is named after the first file in the list with -merged at the end, for example contract-merged.pdf. The title, author and other document properties of the source files are not carried over, so add them in a PDF editor if you need them.

Is merging free and without a watermark?
Yes. The tool is free, needs no sign-up, adds no watermark and has no usage limit. There is no paid version with extra features either, so everything you see on the page is available to everyone.

Does it work on a phone?
Yes, in current versions of Chrome, Firefox and Edge and in Safari 16.4 or later, on Android and on iPhone. Older browsers show a message instead of the tool. Large scans are faster on a computer because it has more memory.

How do I merge two PDF files into one?
Add the first and the second file, check their order with the arrows and click Merge PDFs. For this common case there is a separate page, Merge two PDFs, where you can see straight away which file will come first in the result.
