Unlock PDF - 100% Free Online Tool
Have a password-protected PDF you need to open and use freely? Our Unlock PDF tool removes the password restriction from encrypted PDF files — provided you supply the correct password. Once unlocked, the output PDF can be opened, printed, and edited in any PDF reader without being prompted for a password again. This is the legitimate solution for accessing your own documents when the password was forgotten or inherited with old files.
The tool supports both user passwords (required to open the file) and owner passwords (required to print or modify). Please only use this tool on files you own or have explicit authorisation to unlock. Attempting to unlock files you do not have the right to access may be illegal in your jurisdiction.
Key features: Removes user and owner password restrictions • Requires the correct current password • Output opens in any PDF reader • Supports PDFs up to 100MB • 256-bit SSL during upload • Files deleted within 1 hour

Frequently Asked Questions About Unlock PDF
Everything you need to know about our Unlock PDF tool
Yes, completely free. Our Unlock PDF tool has no hidden costs, no watermarks, and no registration requirement. You can process as many files as you need, each up to 100MB, at no charge. We believe professional PDF tools should be accessible to everyone — students, freelancers, and businesses alike.
Your files are fully protected. All uploads and downloads use 256-bit SSL/TLS encryption during transfer. Processing happens on our isolated Hetzner server infrastructure in Germany — your file is never shared, analysed for commercial purposes, or stored longer than necessary. Every uploaded and processed file is automatically and permanently deleted within one hour of processing.
Supported file types: This tool accepts PDF files up to 100MB each. For files larger than 100MB, use our Compress PDF tool first.
Portable Document Format
Yes — works on any device. The interface is fully responsive and tested on desktop, tablet, and mobile. Touch-friendly upload areas, drag-and-drop support on desktop, and mobile-optimised buttons mean you get the same experience whether you are on a MacBook, an iPad, or an Android phone. No app download is ever required — open your browser and go.
Yes — the correct password is required. This tool is designed for legitimate use: accessing your own password-protected files when the password is known. Enter the password in the provided field and the tool removes the restriction, producing an unlocked copy. If you have forgotten the password entirely and do not have the original, the tool cannot help — encrypted PDFs cannot be unlocked without the correct password without specialised (and typically illegal) brute-force methods.
