Good to know

  • Your files are processed in your browser and never uploaded to our servers.
  • Add an optional password to encrypt the merged PDF; a single file works too if you only want to protect it.
  • Password-protected source files are detected and you're asked for the password before merging.

Frequently asked questions

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

There is no fixed limit. Because merging happens on your device, the practical limit depends on your browser's memory; dozens of typical documents work fine.

Will merging reduce the quality of my PDF?

No. Pages are copied as they are, so text stays selectable and images keep their original quality.

Can I merge password-protected PDFs?

Yes, if you know the password. Enter it when prompted and the file is unlocked locally before merging.
