How to merge PDF files

1. Drop two or more PDF files into the box above, or click to choose them. Each file shows a thumbnail of its first page and its page count.
2. Put the files in the right order: drag them, or use the up and down buttons if you prefer the keyboard or you are on a phone.
3. Click “Merge PDF files”, then download merged.pdf.

Why merge PDF files?

Sending one document is easier than sending five. A single PDF is simpler to attach to an email, upload to a form, print or archive, and it keeps contract pages, invoices or scanned sheets together in the order you chose. Merging in your browser also means a private document never has to travel to someone else’s server.

Frequently asked questions

Is this PDF merger free?

Yes. It’s free, with no sign-up, no watermark and no daily limit.

Are my PDF files uploaded?

No. Your files are read and merged in your browser and never leave your device.

Can I change the order of the files?

Yes. Drag a file to a new position, or use its up and down buttons, which also work with the keyboard. The merged PDF follows the order of the list.

What if a PDF is password-protected or damaged?

The tool tells you which file is the problem. Password-protected files cannot be merged: remove the password first, then add the file again.

How many files can I merge?

Up to 20 files of 50 MB each, 150 MB in total. The limits are lower on phones and tablets, to keep your device from running out of memory.

Does merging change the quality?

No. The pages are copied as they are, without being re-compressed.
