FAQ

Can I protect merged PDFs?

Yes. Merge first, then protect the final file with password.

Will password protection keep file quality?

Yes. Protection adds security without reducing PDF quality.

Is this the same as watermarking?

No. Watermark adds visual text/image, while password protection controls access.
