How PDF unlocking works

Some PDFs are encrypted and require a password to open.
Unlocking requires the correct password.
After successful decryption, some tools can create a new copy without the password if supported.
Not all PDF encryption types are supported by browser libraries.
Unlocking does not mean bypassing access controls without permission.
The original PDF should be kept before saving any modified copy.

User password vs owner permissions explained

A user password is required to open the PDF.
Owner permissions may restrict printing, copying, editing, or page changes.
Removing restrictions should only be done when authorized.
Some PDFs have both user password and owner permission restrictions.
PDF libraries differ in what they can read, modify, or save.
A new unlocked copy may not preserve every advanced feature.

Encryption, passwords, and authorization notes

Encrypted PDFs protect access to content.
The correct password is required.
This tool does not guess passwords.
Forgotten passwords cannot be recovered by this tool.
Only unlock files you own or have permission to modify.
Sensitive PDFs should be handled on trusted devices.
Keep original files before saving modified copies.

Privacy and local processing notes

This implementation checks PDFs locally in the browser using PDF.js. No account is required, and this page does not upload your PDF or password. Passwords should never be logged or stored. Avoid selecting sensitive PDFs unless you trust the device and browser, and keep the original PDF before saving any modified copy.
