FAQ
What type of encryption is used?
PDFGem uses AES-128 encryption, the same standard used by Adobe Acrobat and other professional PDF tools.
What's the difference between user and owner password?
The user password is required to open the PDF. The owner password controls permissions like printing, copying, and editing.
Can I restrict printing or copying?
Yes. You can individually control whether the recipient can print, modify, copy text, or add annotations to the PDF.
Is my password stored anywhere?
No. Your password is used only during encryption in your browser and is never sent to any server.
Can the protection be removed later?
Yes. Anyone with the correct password can unlock the PDF using PDFGem's Unlock PDF tool or any PDF reader.
