Protect PDF
Lock your PDF with a password and decide what people can do with it once it's open.
Drop a PDF to protect
or browse from your device — then choose a password
Password protect a PDF online — strong and simple
Add a password to your PDF to keep contracts, invoices and reports away from prying eyes. Choose a password (or let us suggest a strong one), then decide whether people who open the file can print, copy or edit it. The PDF is encrypted with that password when you download it, and you can keep editing it in the AI Studio first.
Two layers of security
Set an open password, restrict actions, or combine both.
Private by design
Your file and password stay private to you.
Works everywhere
Protected PDFs open correctly in any standard PDF reader.
Frequently asked questions
Files are encrypted with the PDF standard security handler, the same method used by Adobe Acrobat and most PDF software, so protected files open correctly everywhere a password is required.
