Frequently asked questions
What kind of password protection does this add?
A real, standard PDF encryption password — the same kind Adobe Acrobat and other PDF readers recognize. The file itself is encrypted, not just locked by an app.
What is the difference between the open password and the permissions password?
The open password is required just to view the file. The permissions password additionally controls whether the file can be printed, copied from, or edited once opened — readers that respect PDF permissions will restrict those actions unless someone enters this password.
Can I remove a password without knowing it?
No. Removing protection requires the correct password, exactly like opening the file normally — this tool cannot bypass or crack a forgotten password.
Is my file uploaded to a server?
No. Your PDF and password are processed entirely inside your browser — nothing is sent anywhere, including the password itself.
Is it free, with no limits?
Yes. No account, no watermark, and no limit on how many files you can process.
