You can lock text in Adobe Acrobat by setting a permissions password so that other users cannot make unauthorised changes to a PDF. Acrobat offers several setting options that allow you to determine the type of changes other users can make to a document. You can allow no changes at all; insertions, deletions and page rotations; form filling and digital signatures; comments, form filling and digital signatures; or everything but page extracting. An additional option allows you to enable or disable the ability to copy text, images and other data from the PDF.
- Skill level:
Open the PDF document in Acrobat.
Click on the “Advanced” menu, choose “Security” and select “Encrypt with Password.” Click the “Yes” button in the pop-up window.
Place a check mark in the box next to “Restrict editing and printing of the document.” Type a password in the “Change Permissions Password” box.
Set the “Changes Allowed” pull-down menu to your desired level. Use the check box to indicate whether you want to “Disable copying of text, images and other content.”
Click “OK” to apply the changes to the PDF.
