Frequently Asked Questions

Is there a file size limit?

Each PDF can be up to 100 MB. You can merge up to 20 PDFs in one go.

Are my files kept private?

Yes. Files are sent over HTTPS, processed immediately, and auto-deleted from our servers within 1 hour. We never share your files.

Will merging reduce PDF quality?

No. Merging is a lossless operation — original resolution, fonts, and formatting of every page are preserved exactly.

Can I merge password-protected PDFs?

Not yet. Password-protected PDFs need to be unlocked first. We plan to add an unlock feature soon.

Why does it take a few seconds?

Your files are uploaded to our server, processed by a PDF engine, then the merged file is sent back. Larger files naturally take a bit longer.
