Unlock and Delete via Highlight Properties

The 'Locked' option on a PDF highlight is designed to prevent accidental changes. It is not a permanent restriction, provided the document itself allows commenting and editing.
Right-click on the locked highlight in your PDF document and select 'Properties' from the drop-down context menu.
In the Properties dialog box, locate and clear the 'Locked' checkbox at the bottom, then click 'OK' or apply the change.
Once unlocked, click the highlight to select it and press the 'Delete' key on your keyboard, or modify the annotation as needed.

Frequently Asked Questions
Why is the 'Properties' option grayed out when I right-click a highlight?
This usually indicates the entire PDF document is restricted or password-protected against editing and commenting. You must enter the permissions password to unlock the document before you can alter annotations.
Does locking a highlight prevent other users from unlocking it?
No, locking an annotation merely prevents accidental edits during reading. Anyone using standard PDF editing software can right-click and unlock it, unless the PDF itself is encrypted with an editing password.
Can I lock or unlock multiple highlights at once?
Yes, in many advanced PDF editors, you can hold the Ctrl (or Cmd on Mac) key to select multiple highlights, right-click to access Properties, and toggle the 'Locked' status for all selected annotations simultaneously.
