- Scenario
- Editing a PDF or adding notes using the freehand drawing tool on a mobile device.

Ensure your Acrobat Reader Mobile app is updated to the latest version via the Google Play Store or Apple App Store, as interface layouts and tool placements frequently change between updates.
Locate the Eraser Tool in the Comment Menu
The eraser tool is typically nested alongside the drawing tools in the comment section. Follow these steps to access it.
In many mobile PDF readers, the eraser is not a standalone primary tool but is instead grouped with the pen and highlighting options within the specific annotation or drawing toolbar.
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.
Choose the 'Draw' option, typically represented by a pen icon, from the available bottom toolbar.
Look for the Eraser icon next to the pen color and thickness settings. Tap it to activate the eraser mode.
Swipe your finger directly over the drawn lines or annotations on the screen that you wish to remove.

Troubleshoot Missing Toolbar Icons
If the eraser icon is completely missing from the interface, it may be due to an application glitch or version bug.
Edit PDFs Easily with WPS Office for Mobile
If you are struggling to find annotation tools in your current PDF reader, switch to WPS Office. It offers a highly intuitive mobile interface where drawing, highlighting, and erasing tools are neatly organized and just one tap away.
- 1. Download WPS Office: Install WPS Office from the Google Play Store or Apple App Store and open the application.
- 2. Open PDF and Access Tools: Open your PDF file, tap the 'Tools' menu at the bottom of the screen, and select 'Annotation'.
- 3. Use the Eraser Tool: Select the 'Pen' tool to draw. Whenever you need to remove a mistake, tap the prominently displayed 'Eraser' icon right next to it.
- 4. Save Changes: Tap 'Done' in the top corner to securely save your cleanly annotated PDF document.

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.
