Remove a password from a PDF you can open
A PDF that asks for a password every time it opens gets old fast. Give the tool the password you already have and it writes out an unlocked copy with the encryption removed. Decryption happens with WebAssembly inside your browser, which means the file and the password are both handled on your device and neither is ever transmitted.
How to remove a password from a PDF
Add the protected PDF
Drop the encrypted file on the page. The tool detects that it's password-protected.
Enter the password
Type the password you use to open it. It's used locally to decrypt the file and is never sent anywhere.
Download the unlocked copy
Press Unlock. A copy with the encryption stripped out is written in your browser and downloaded.
What Unlock PDF can do
Password stays local
Decryption runs in the tab, so the password never touches a network.
Content untouched
Only the encryption is removed — pages, text and images are unchanged.
Permission locks too
Restrictions on printing and copying come off with the encryption.
Free and unlimited
No account, no per-file charge, no size cap.
Unlock PDF — frequently asked questions
Can this open a PDF if I don't know the password?
No. This tool removes protection from a document you can already open — it doesn't crack, guess or bypass anything. Without the password there's nothing it can do.
Is it safe to type my PDF password into a website?
Here, yes, because there is no server to type it into. The page holds the password in memory in your own tab to decrypt the file, and it's gone when you close it. You can verify that by disconnecting from the network and watching the tool still work.
Can I remove restrictions on printing or copying?
Yes. Those permission flags are part of the encryption, so they come off with it when you unlock the document with its owner password.
Do my PDFs get uploaded to a server?
No. Every tool on Notoo Tools runs as JavaScript and WebAssembly inside your browser tab. There is no server that receives your files — you can disconnect from the network after the page loads and the tool keeps working.
Do I need an account or a subscription?
Neither. There's no sign-up, no email, no free-tier limit and no watermark. Bookmark the tool and it opens straight into the work.
