Frequently asked questions
Common problems and fixes
- The password is not asked when I reopen the file
Why: your PDF viewer remembered the password for the session, or you are opening the original rather than the protected copy.
Fix: test the newly downloaded file in a different viewer or an incognito window — the encryption is real and applied on download.
- I forgot the password I set
Why: the file is genuinely encrypted — there is no backdoor and no recovery key.
Fix: no tool can recover it honestly; keep document passwords in a password manager from the start.
- Some apps ignore the restrictions I set
Why: permission restrictions are honoured by compliant readers but are not cryptographically enforced against all software.
Fix: for real confidentiality use full encryption (open password), not permission flags alone.
