Unlock PDF
Remove a password you already know, so the file stops asking every time.
This tool runs in your browser. Your document is not uploaded. What happens to your files
How it works
- Choose an encrypted PDF.
- Enter the password you already know.
- Remove protection and download the unlocked copy.
Key benefit
Decryption runs locally and leaves the original file untouched.
Supported files and key limits
Input: PDF. Output: PDF.
The tool cannot recover or bypass an unknown password.
This does not recover a lost password
It removes a password you can already type. If you cannot open the document, nothing here will help. The password is the decryption key, and without it the page contents are ciphertext with nothing to read. A site that promises otherwise is either running a brute-force attack on your file or not doing what it says.
If the document came from an institution such as a court, a bank or an insurer, the fastest route is asking them to send it again without protection.
Why remove a password you know
Bank and payslip PDFs often arrive protected with something derived from your date of birth or account number. That works for email and is awkward afterwards: you cannot search across them, preview them in a file manager, or attach one to a filing without the recipient hitting the same prompt. Merge and Compress also refuse protected files, so unlocking once is often the first step.
What survives the rewrite
Pages, text, images, links, and comments remain. Bookmarks, form-field structure and document properties such as the title, author and subject do not carry over, so keep the protected original when those features matter.
PDFOak builds a new, unprotected document around the pages, and that is what drops the bookmark tree. The title and author were never available to copy, because an encrypted PDF does not let them be read.
Only unlock documents you are entitled to
A password is a statement about who the sender expected to read the file. Removing it from your own bank statement is housekeeping. Removing it from something forwarded to you, or sealed by a court, may not be, and this tool cannot tell the difference. That judgement is yours.
Putting a password back
To protect the unlocked copy again, use Lock PDF, which uses AES-256 when your browser supports it and AES-128 otherwise. Your document and password are not uploaded in either direction.
