Frequently Asked Questions (FAQ)
Is my PDF uploaded to a server during password encryption?
No, all encryption happens locally on your computer or mobile device using Web Crypto and client-side processing. Your document is never transmitted online.
What encryption standard is used?
Our tool applies standard PDF encryption algorithm (AES 256-bit / RC4 128-bit) to ensure unauthorized users cannot open or view your file contents.
What happens if I forget the password?
Because encryption is computed locally and we never store your passwords or files, we cannot recover forgotten passwords. Make sure to record your password securely.
