How strong is the encryption used to protect my PDF?
We utilize industry-standard 256-bit AES encryption. This is a military-grade security level that makes it practically impossible to brute-force open the document without the correct password.
Frequently Asked Questions About Protect Pdf
Security Features
Will this password prevent people from printing my file?
Yes, by encrypting the file, you are applying an 'Open Password'. Users cannot view, copy text, or print the document without first providing the password.
Do you save my password on your servers?
No, we never store or log your passwords. The encryption happens on the fly, and if you forget the password you used, we have no way to recover the document for you.
Usage & Compatibility
Can I set a password with special characters?
Yes, you can use letters, numbers, and symbols. We highly recommend using a long passphrase with a mix of characters for maximum document security.
Will the protected PDF open in any viewer?
Yes, standard 256-bit AES encryption is supported by Adobe Acrobat, Apple Preview, Chrome, Edge, and all modern PDF readers. They will simply prompt the user for the password.
Can someone easily remove the password using an unlock tool?
Only if they know the password. 'Unlock' tools (including ours) merely strip the encryption *after* you provide the correct password. They do not hack or bypass the security.
