What encryption does the PDF password protection use?

We use strong encryption compatible with all major PDF readers including Adobe Acrobat. Your documents are securely protected with industry-standard algorithms.

Can I remove the password later?

Yes. Use our free Unlock PDF tool with the original password to create an unlocked copy, then set a new password if desired.

Is my password stored on your servers?

No. All encryption happens 100% in your browser. Your password and files are never uploaded or stored on any server.

How strong should my PDF password be?

We recommend at least 8 characters combining uppercase, lowercase, numbers, and symbols. Longer, more complex passwords provide stronger protection.

What happens if I forget my PDF password?

Please save your password securely. Once a PDF is encrypted, the password cannot be recovered or reset by any tool, including ours.
