Frequently Asked Questions

How secure is the encryption?
We use AES-128 encryption, which is an industry-standard encryption algorithm. This is the same level of security used by many professional PDF tools and provides strong protection for your documents.
Is my PDF uploaded to a server?
No. Your PDF file never leaves your device. All processing happens entirely in your browser using JavaScript. We don't have any servers that handle your documents - your privacy is guaranteed.
What if I forget my password?
Since all processing happens locally and we never see your password, there is no way to recover it. Make sure to remember your password or store it securely in a password manager.
Can I remove the password later?
Yes! If you know the password, you can use our Unlock PDF tool to remove password protection from your document.
