Protect PDF From Editing
This page is preset to switch off editing and comments, so people who open the file can read it, and print or copy if you allow it, but not change it in standard PDF readers. To lock PDF from editing you also set a password that's needed to open the file; share it only with the people who should read it.

How to stop others from editing your PDF
- 1Select the PDF.

Good to know
- Keep an unprotected copy for yourself. To make changes later, edit the original and protect it again.
- Turn off Allow copying too if you don't want text copied out and pasted into another document.
- Standard PDF readers respect these locks, but not every tool does. For an official record, flatten the PDF first, then protect it.
- Don't send the password in the same message as the file.
Frequently asked questions
Can people still open and read the PDF?
Yes, with the open password you set. Once it's open, editing and commenting are blocked in PDF readers that respect permissions.
Can I lock editing without an open password?
Not with this tool. It always sets an open password together with the permissions.
Do you keep my file or password?
No. The file is uploaded encrypted, processed and deleted right away, and nothing is stored on our servers.
