How to Protect PDF with Password
- Step 1: Upload the PDF you want to protect
- Step 2: Set an owner password (required) — this controls all permissions
- Step 3: Optionally set a user password — required to open the file
- Step 4: Configure permissions: allow or restrict printing, copying, and editing
- Step 5: Click 'Protect PDF' to encrypt and download the secured file
💡 Pro tip: The owner password protects the permissions themselves. Without it, no one can change the security settings. The user password is what recipients need to open the file.
