About PDF Protection


Password-protecting your PDFs is essential for securing sensitive documents. Our tool uses industry-standard AES-256 encryption to ensure your documents remain private.

You can set two types of passwords: a user password (required to open the document) and an owner password (required to change permissions or remove protection).

Permission controls let you restrict specific actions: printing, copying text, editing, and form filling. You can allow some actions while restricting others based on your needs.

The protected PDF remains fully functional in all standard PDF readers. Recipients simply enter the password to access the document according to your permission settings.

For highly sensitive documents, you can enable strong encryption that meets enterprise security standards. The protection is compatible with all major PDF applications.
