How does the PDF protector work?
billu.fun's PDF Protector lets you secure your PDF files with a password entirely in your browser. This means your sensitive documents never leave your device and are never uploaded to any server.
To secure a PDF, just drag and drop the file into the area above. Enter the password you wish to use, and click "Protect PDF". The tool will encrypt the file using the password provided, and you can download the secured version immediately.
Because everything happens locally on your machine, this tool is perfectly safe for highly confidential documents, financial statements, and private records.
