Frequently Asked Questions
Is my PDF or password uploaded to a server?
No. The decryption happens entirely in your browser. Your PDF and password never leave your device.
What encryption methods are supported?
AES-256 and RC4 encrypted PDFs are supported, which covers the vast majority of password-protected PDFs.
What if I don't know the password?
This tool requires the correct password to unlock the PDF. It cannot crack or bypass password protection on files you don't have authorization to open.
