Change the Default Properties for Annotations

By modifying an existing annotation and setting its unlocked state as the new default, all future comments of the same type will be added unlocked.

Adobe Acrobat uses the properties of an existing annotation as the baseline for future comments if instructed to do so. If the default somehow became 'locked', you simply need to reverse the process using a single unlocked annotation.

1
Unlock an existing annotation

Right-click any locked annotation in your PDF, select 'Properties', navigate to the bottom of the dialog box, uncheck the 'Locked' checkbox, and click 'OK'.

2
Set the unlocked state as default

Right-click the same annotation you just unlocked, and choose 'Make Current Properties Default' from the context menu.

3
Verify the change

Add a new annotation of the same type to the document to confirm that it is now unlocked by default and can be edited freely.

Annotation Types: Default properties in Acrobat apply to specific annotation types. If you use highlights, sticky notes, and text boxes, you will need to repeat this process for each type.

Frequently Asked Questions

Why did Acrobat start locking my annotations by default?

This usually happens if you or another user accidentally clicked 'Make Current Properties Default' on an annotation that was previously locked. Acrobat then applies this locked state to all subsequent annotations of that specific type.

Can I unlock multiple annotations at the same time?

Yes. Open the Comments pane on the right side of the screen, hold down the Ctrl key (or Cmd on Mac) to select multiple comments, right-click the selection, choose 'Properties', and uncheck the 'Locked' box to unlock them all simultaneously.

Does changing the default property affect previously locked annotations?

No, changing the default properties only applies to new annotations you create from that point forward. Existing locked annotations must be unlocked manually.
