Frequently asked questions
Is Unlock PDF free?
Yes, completely free with no sign-up and no watermark.
Can it unlock a PDF if I forgot the password?
No. It only removes a password you already know. It does not guess or crack passwords.
What is a restricted PDF?
Some PDFs open without a password but block printing, copying or editing using an owner password. If you own the document or have permission, the tool can save an unrestricted copy.
Is my file uploaded?
No. Everything runs in your browser using the open-source qpdf engine, so the document and password stay on your device.
Why can't other GrabCast PDF tools open my file?
