About Protect PDF
Password-protect and encrypt PDFs so only people with the password can open or edit them. Choose whether to require a password to open the document and/or to restrict printing, copying, or editing. Upload your PDF, set the password and options, and download the protected file.
Protection is applied on our servers; we don’t keep your file after you download. For removing protection from an existing PDF, use Unlock PDF. More PDF tools are available on the home page.
What you can do
- Set open and/or permission passwords
- Restrict printing, copying, editing
- No account needed
- Files deleted after 1 hour
