Questions & answers
Is unlocking a PDF free?
Yes. You get 3 free uses a day with no signup or account. If you need more, a $3 day pass or $9/month plan lifts the limit.
Do I need to already know the password?
Yes. This removes a password from a PDF you can already open — it's not a way to crack or guess a password you don't know.
What if I enter the wrong password?
You'll get a clear error instead of a broken file. Double-check the password and try again.
Will the unlocked PDF have a watermark?
No. Stamped never adds a watermark, stamp, or badge to your files — you get back the same PDF, just without the password.
Are my files kept private?
Your file is sent securely for processing and isn't stored afterward. It isn't shared, indexed, or used for anything else.
Does it work on Mac, Windows, and phones?
Yes. Stamped runs entirely in your browser, so there's nothing to install — it works the same on any computer or phone. Files can be up to 25MB.
