Privacy & File Limits
Client-Side Privacy: Your encrypted file and the password you enter are processed entirely within your browser session. Neither the document nor the password is ever sent across the network or stored on any server.
Usage Limits: Requires the valid document password. Brute-force password cracking is strictly unsupported. Decrypts standard AES-256, RC4-128, and RC4-40 files up to 50 MB. Note: AES-128 (/AESV2) encryption is not supported by our client engine; an honest error message is displayed rather than producing a corrupt file.
Frequently Asked Questions
Which encryption algorithms are supported by the unlock tool?
Our client-side decryptor supports standard password-authorized AES-256 (Revision 5/6), RC4-128, and RC4-40. Documents protected with legacy AES-128 (/AESV2) encryption are currently unsupported and will display a clear advisory.
Can this tool bypass a password if I have forgotten it?
No. Our tool is an authorized decryptor designed to remove password restrictions when you already know the password. It does not perform illegal brute-force password cracking.
Does unlocking a PDF damage its formatting or links?
No. The decryptor decrypts data streams in memory while preserving document fonts, vector layouts, form fields, and table structures exactly as authored.
Is it safe to unlock confidential documents like payslips?
Yes. Decryption executes 100% client-side in your local browser memory. No passwords or unencrypted files are ever sent over the network.
