About Restrict permissions

Sets PDF permission flags with AES-256 encryption. Compliant readers (Acrobat, Chrome, Preview…) honour them, but permissions are not strong protection against determined users — use an open password for confidential files.

How it works

  1. Add your pdf — drag and drop or browse.
  2. Choose your settings.
  3. Click the action button and wait a moment.
  4. Download the result. Nothing was uploaded.

Good to know

  • Permission flags are honoured by compliant readers but can be bypassed by some software; they are not encryption of the content against the reader.
