Frequently Asked Questions
How strong is the encryption?
The file is encrypted with AES-256, the strongest standard encryption in the PDF specification, which all modern PDF readers support. In practice, protection depends on your password, so use a long one that's hard to guess.
What if I forget the password?
It can't be recovered. The password isn't stored anywhere, including by us. Keep it in a password manager, and keep an unprotected copy of the original if you might need it.
Are the permission restrictions enforceable?
Print, copy, and edit restrictions are honored by standard readers like Adobe Acrobat and browser viewers, but some third-party tools ignore them. Only the open password actually prevents access to the content.
Is my password sent anywhere?
No. Encryption happens in your browser, and neither the PDF nor the password is uploaded.
