How do I merge PDF files?

Add two or more PDFs, arrange them in the order you want, then click Merge PDF. Your combined file downloads in seconds.

Is there a limit on how many PDFs I can merge?

You can merge up to 50 PDFs at once, with up to 2 GB per file.

Can I merge password-protected PDFs?

Yes. Enter the password for the protected file when prompted and it is merged like any other.

Can I process very large PDFs?

Yes. Uploads are split into small parts and sent in parallel, so PDFs of 1 GB and more upload reliably and resume after a dropped connection.

Files are sent over an encrypted connection, processed on our servers and deleted automatically within an hour. You can also delete them immediately from the download screen. We never share or read your documents.
