With PDF Converter, you can set user permissions to restrict what others can do to your file. For example, you could share your file with a colleague or friend to check and review - allowing access to the document to view it, but not allow modification of the file itself.
Easily set user restrictions by opening your PDF file, then clicking "Set Permissions" under the Security tab in PDF Converter.
Check the "Apply restrictions to document" checkbox to access the permissions menu.
Now you can choose which permissions you would like to allow or disallow on your file.
Once you're happy with your choices, set and confirm a password, click Apply, and save your file.
Now, whenever a user attempts to perform a restricted action, they'll need to provide the Document Owner's password.
Remove User Permissions from a PDF
If you'd like to remove user restrictions which you have set before, simply click the Set Permissions button and provide your password for the permissions of the file. Then, uncheck the "Apply restrictions to document" checkbox, click Apply, then save your file.
