TL;DR: Upload a PDF, set an owner password and choose permissions (print, copy, modify) — download the locked copy.
Set PDF permissions online — control who can print, copy, edit, or annotate your PDF documents. Apply granular access controls with owner password protection.
Every PrivaTools tool — including PDF Permissions — is genuinely free with no premium tier, no per-day limit, and no watermark on the output. Files are deleted from the server within seconds of your download completing. Source code: github.com/taiyeba-dg/privatools.
User password = required to OPEN. Owner password = required to override permissions (print, edit). Use Protect PDF for both; this tool sets only the owner password + permission flags.
It's enforced by readers as a courtesy — Adobe Acrobat respects it strictly, some open-source readers ignore it. For real security, encrypt with a user password.
Only if allow_copy is true. If false, the reader disables text selection. Note: screenshots still work (no PDF protection can prevent that).
