Merge PDFs
Combine several PDFs into one, in whatever order you choose.

Frequently asked questions
Is it safe to merge confidential PDFs here?
Yes. The merging happens in your browser and the files never leave your device.
Is there a file size limit?
There is no upload limit because nothing is uploaded. Very large files depend on your device’s memory.
Can I merge password-protected PDFs?
Encrypted PDFs need to be unlocked first. Remove the password in your PDF reader, then merge them.
