What is Unlock PDF?
Unlock PDF removes password encryption from a PDF, given a password that already opens it. It's the reverse of Protect PDF: instead of adding a password, it strips one away so the file can be opened, edited or shared freely afterward. It supports AES-256, AES-128 and legacy RC4 encrypted PDFs, decrypted entirely on your device.
How to use Unlock PDF
- Choose a password-protected PDF, or drag and drop it into the tool.
- Enter its password.
- Click Unlock PDF and download the file without a password.
Features
- Supports AES-256, AES-128 and legacy RC4-encrypted PDFs.
- Works with either the open password or the owner/permissions password.
- Keeps pages, text, images and formatting exactly as they were.
- 100% client-side — your PDF and password never leave your browser.
Frequently Asked Questions
Is my PDF or password uploaded to a server?
No. Unlock PDF decrypts your file entirely in your browser. Neither the PDF nor the password you enter is ever sent to our servers.
Do I need to know the password?
Yes. This tool removes password protection from a PDF you can already open — it can't guess, crack or recover a password you don't know. Enter either the document's open password or its permissions (owner) password.
What encryption does this support?
AES-256 and AES-128 (the PDF 2.0 and PDF 1.6+ standards), as well as legacy RC4 encryption. If a PDF uses an unusual or non-standard security handler, this tool will tell you rather than produce a broken file.
Will the unlocked PDF look any different?
No. Unlock PDF only removes the encryption and password requirement — the pages, text, images and formatting are left exactly as they were.
Can this add a password instead of removing one?
No, this tool only removes an existing password. To add password protection to a PDF, use Protect PDF.
