PDF Security: passwords and viewer permissions
Use PDF Security when you need to save a PDF with an owner password, optional open password, and permission settings for common viewer actions. The tool copies the PDF pages into a new secured file and downloads it as secured.pdf.
Example workflow
Upload a draft PDF, enter an owner password, choose whether viewers can print or copy content, and download the secured PDF. Open the result in the PDF viewers your audience uses to confirm the permissions behave as expected.
Limits to check
- Owner password: Required before the page can apply the permission settings.
- Viewer behavior: PDF permissions are interpreted by the app that opens the file and should be tested before sharing.
- Not redaction: This tool does not remove sensitive text, images, or hidden PDF objects from the document.
