PDF Unlock

PDF Unlock is a free browser tool that removes the password from a PDF you can already open — one file or a whole folder at once, with nothing uploaded.

PDF Unlock removes the password from PDFs you can already open — drop in one file, or a whole folder to unlock in batch, and download the results as <name>_unlocked.pdf. It decrypts with the password you supply and re-saves without it. Your files and your password never leave your computer. Built by Nirav Bhatt at Brain Bound Learning.

Silent screen recording of PDF Unlock: a locked PDF is dropped onto the page, the password that already opens it is typed in, and the unlocked copy downloads as <name>_unlocked.pdf; batch mode then does the same for a whole folder. Every step is written out in About PDF Unlock below.

PDF Unlock — remove a PDF password without uploading the file

PDF Unlock takes a password-protected PDF that you can already open, decrypts it with the password you supply, and saves a copy that no longer asks for one. It is not a password cracker — you have to know the password. What it removes is the chore of typing it every single time, and the owner restrictions (no printing, no copying) that often ride along with it. Everything happens inside your browser: the file and the password never leave your computer, which is the whole point when the PDF in question is a bank statement, a payslip, or a medical report.

What the terms mean

User password (also called the open password)
The password a PDF asks for before it will open at all. This is the one PDF Unlock removes: you type the password that already works, and it saves a copy that no longer asks.
Owner password (also called the permissions password)
A separate password that restricts what you may do with a PDF you can already read — printing it, copying text out of it, extracting pages. Re-saving the file drops these restrictions along with the open password.
Not a password cracker
PDF Unlock never guesses or brute-forces anything. If you cannot open the PDF today, it cannot open it either.
Batch mode
Point it at a folder instead of a file. Every PDF inside is unlocked with one shared password and the results download together as a zip; any file needing a different password is reported as failed and left out.

How it works

  1. Drop in a PDF — or click to pick one from a file dialog.
  2. Hit Unlock and type the password that opens it.
  3. The unlocked copy downloads as <name>_unlocked.pdf. Your original is untouched.
  4. Batch mode: point it at a folder instead. Every PDF inside is unlocked with one password and the results download together as a zip.

What people use it for

Frequently asked questions

Can it crack a PDF password I don't know?

No. It is not a password cracker. You supply the password that already opens the PDF, and it saves a copy that no longer asks for one.

Do my PDFs get uploaded anywhere?

No. The whole thing runs in your browser. Your files and the password you type never leave your computer — there is no server to send them to.

Can it unlock several PDFs at once?

Yes. Batch mode takes a folder and unlocks every PDF inside it, then downloads the results as a single zip. Every PDF in the folder must open with the same password; any file that needs a different one is reported as failed and left out of the zip.

What are the unlocked files called?

Each output keeps its original name with _unlocked added — statement.pdf becomes statement_unlocked.pdf. Your original file is never modified.

Does it remove printing and copying restrictions?

Yes. Re-saving the PDF drops owner restrictions such as no-print or no-copy along with the open password.

Is it free?

Yes — free, with no account and no watermark.

Does it work offline?

Yes. Once the page loads it runs entirely in your browser — no internet connection, no sign-up, and no login. The downloadable single HTML file works completely offline.
