How to Move, Resize, and Snap Comment Drawings in Acrobat PDF
Question details
The user is unable to effectively move, resize, or snap comment drawings such as ovals and rectangles in Adobe Acrobat.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to reposition or resize PDF shape annotations, particularly after the drawing has been locked and then unlocked.
- Observed behavior
- The drawing object becomes unresponsive, difficult to move with the mouse, or fails to snap to the document's grid.
Ensure that your drawing object is currently unlocked and that the Select tool is active before attempting to move it.
Use Arrow Keys and Enable Grid Snapping
Selecting the object and using keyboard arrows provides precise movement and forces the object to snap to the grid.
In some cases, mouse dragging may become unresponsive due to selection glitches. Using the arrow keys bypasses this issue and allows for accurate alignment when grid snapping is active.
Click on the 'Select' tool (the arrow icon) in the Acrobat toolbar, then click directly on the oval or rectangle comment drawing to highlight it.
Press the Up, Down, Left, or Right arrow keys on your keyboard to move the object incrementally.
To force the object to align perfectly, go to 'View', hover over 'Show/Hide', select 'Rulers & Grids', and click 'Grid'. Moving the object with your keyboard will now snap it to the nearest gridline.
Verify Lock Status and Update Adobe Acrobat
Ensure the drawing is not locked in its properties and update the software to fix known bugs with unlocking annotations.

Frequently Asked Questions
Why is my PDF comment drawing stuck and unable to be moved?
The drawing might be locked in its properties, or you may have encountered a software bug that occurs after unlocking an object. Ensure the 'Locked' property is unchecked by right-clicking the object. If it remains stuck, try moving it with your keyboard's arrow keys.
How do I snap an object to the grid in a PDF?
First, enable the document grid by going to View > Show/Hide > Rulers & Grids > Grid. Once the grid is visible, selecting the object and moving it with your keyboard's arrow keys will automatically snap it to the nearest gridline.
Do locked PDF annotations become permanently immovable?
No, locking an annotation is simply meant to prevent accidental changes. Once you right-click the object, open Properties, and uncheck 'Locked', it should regain its mobility. If it does not, updating your PDF software usually resolves the glitch.
