Encrypted PDFs can be annoying when you are the one who locked them. You set a password months ago, and now you just want the file open or editable again. Removing the protection from a document you own is a simple, legitimate job.
ThothBox's Unlock PDF tool lets you remove the password from a PDF you have the password for, directly in your browser. The process runs locally, so the file never leaves your device.
Unlocking a PDF is proper only when you have the right to access it — typically because you created it, or you were given the password by its owner. The tool takes your password and removes the encryption, which is exactly what you would use for your own documents.
It is important to be clear: this tool does not crack or bypass passwords. If you do not know the password, it cannot help, and attempting to unlock documents you do not own would be improper. Only unlock files you are entitled to access.
