PDF Encryption
Encrypt PDF Online - Set an Open Password and Control Print, Copy, and Edit Permissions
What is PDF encryption?
PDF encryption lets you set an open password for a PDF and use PDF permissions to control printing, copying content, editing, form filling, and adding comments. Processing is completed locally in your browser, and neither the PDF nor the password is uploaded to a server.
What can PDF encryption do?
You can protect a PDF with an open password and configure permissions for printing, copying, and editing. Advanced permissions can also control form filling and adding comments.
What is the difference between an open password and PDF permissions?
An open password controls whether a user can open the PDF. Permission settings control certain actions after the file has been opened, such as printing, copying, editing, filling forms, or adding comments. Both can be configured at the same time.
How do I password-protect a PDF?
Select a PDF file, enter and confirm a password, then choose whether printing, copying, editing, and other advanced permissions should be allowed. Click Encrypt PDF to create the protected PDF.
Is PDF encryption secure?
The password is used locally in your browser to generate the encrypted PDF. It is not sent to a server, included in the URL, or uploaded. The encrypted file is generated and downloaded directly by your browser.
Will an encrypted PDF be larger?
Encryption changes the internal structure of a PDF, so the output file size may differ slightly from the original. A small increase in size is normal.
What if I forget the PDF password?
This tool does not store your password and does not provide password-cracking functionality. If you forget the open password, contact the file owner or retrieve it from a legitimate password record.
What is the difference between PDF encryption and decryption?
PDF encryption adds an open password and permission restrictions to a PDF. PDF decryption removes a password and permission restrictions when you already know the current password. If you need to remove an existing PDF password, use the PDF decryption tool.
Are the PDF and password uploaded to a server?
No. Both the PDF and password are processed locally in your browser. They are not uploaded to a server or written to server logs.
