You set a password on a PDF months ago and now you just want quick access without typing it in every time. Or a document you own came with a password you know but find annoying to re-enter. Either way, removing a password you already have is a two-minute job.
Why PDFs End Up Password-Protected
- You protected the document yourself with PDFslime's Protect tool or another app, and no longer need the password.
- A colleague or client sent you a password-protected file along with the password, and you'd rather work with an unlocked copy.
- You're consolidating several protected files (invoices, statements) and need them unlocked before you can merge or split them.
How to Remove the Password

The one you already know

Get your unlocked PDF

- Drag and drop the locked PDF onto the page.
- Type in the password used to open the document.
- Click Unlock — the password is verified and stripped.
- Download the unlocked copy.
The entire process happens on your device — the PDF and password never leave your browser.
Only for Documents You Own
This tool removes a password when you already know it. It's designed for documents you own or are authorized to modify — not for gaining access to someone else's protected files. PDFslime doesn't offer password guessing or cracking; if you don't know the password, you'll need to get it from whoever set it.
Avoiding This in the Future
- Save passwords in a manager — Bitwarden, 1Password, or your browser's built-in manager.
- Keep an unprotected backup in a secure folder for documents you control.
- Use a memorable passphrase next time, like "blue-elephant-jupiter-7", instead of a hard-to-recall string.
