Locate the Eraser Tool in the Comment Menu

Open Comment Tools

Open your PDF document in Acrobat Reader Mobile and tap the pencil icon (usually located at the bottom right) to access the 'Comment' or 'Edit' menu.

2
Select the Draw Tool

Choose the 'Draw' option, typically represented by a pen icon, from the available bottom toolbar.

3
Activate the Eraser

Look for the Eraser icon next to the pen color and thickness settings. Tap it to activate the eraser mode.

4
Erase Annotations

Swipe your finger directly over the drawn lines or annotations on the screen that you wish to remove.

Frequently Asked Questions

Why can't I erase the original text in my PDF using the drawing eraser?

The drawing eraser tool is specifically designed to remove freehand annotations, shapes, or markings added via the comment tools. To delete or modify the original text embedded in the PDF, you need to use a dedicated 'Edit PDF' text editing feature.

Is the eraser tool available in the free version of Acrobat Reader Mobile?

Yes, basic commenting tools, including the freehand drawing pen and the eraser, are generally available to all free users without requiring a premium subscription.

How do I instantly undo a drawing mistake without switching to the eraser?

You can quickly tap the curved 'Undo' arrow icon typically located at the top menu bar of the app. This will revert your last drawing stroke immediately, which is often faster than manually switching to the eraser tool.
