Merge PDF files
Combine several PDFs into a single file, in the order you choose. Your files never leave your computer.
Choose the PDFs you want to combine
or drop them here · you can pick several at once
Processed in this browser: your file is never uploaded to any server. Turn on airplane mode once the page has loaded and it keeps working. Check it yourself
How to use it
- Choose the PDFs (you can select them all at once).
- Put them in order by dragging, or with the arrows.
- Tap “Merge and download”.
Good to know
- Pages are copied as they are: text stays selectable and links keep working.
- Fillable forms may lose their fields when combined with other files. If that matters, fill them in and save them first.
- If a file carries a certificate-based digital signature, merging it makes that signature invalid: any change to a signed PDF does.
- Password-protected files can’t be merged until they open freely: unlock them first with Unlock PDF.
- Want to reorder or delete pages afterwards? Use Organize PDF.
- Does the merged file have to stay under a size limit, or are you mixing photos with PDFs? Prepare for upload merges, fits each page to the sheet and keeps it under the limit.
Questions
Is there a limit on files or pages?
We don’t set one. The only limit is your device’s memory: on a desktop computer, merging hundreds of pages takes a few seconds.
Can I combine images and PDFs?
Turn the images into a PDF with JPG to PDF first, then merge that file with the others.
Is it really free, with no watermark?
Yes. There’s no account, no daily cap and no watermark. It runs in your browser, so there’s no server time for us to charge you for.
