How to Annotate a Screenshot on Chromebook
Add arrows, text, and highlights to a screenshot using built-in tools.
Last verified: February 21, 2026
Chromebook opens every screenshot in the built-in Gallery app, which has a basic annotation toolbar accessible via the edit pencil icon. The tools cover pen drawing, text insertion, and cropping, which handles the majority of documentation and communication use cases without additional software. For more advanced annotation — callouts, arrows, numbered steps — opening the screenshot in a Google Slides or Google Drawing tab from the browser provides substantially more formatting options since Chromebook works best in the web app ecosystem.
Quick Steps
Follow in order for the fastest result.
- 1Take a screenshot and click the preview thumbnail. Use the built-in editor to add notes, crop, and highlight areas.
- 2Add callout arrows and text labels to draw clear attention to specific areas.
- 3Save or share the annotated image using the Done / Share button in the editor.
Still Not Working?
Try these if the steps above didn't help.
- If the auto-preview disappears, open the screenshot from your gallery and edit from there.
- Use Paint (Windows) or Preview (macOS) as built-in alternatives if dedicated tools are missing.
- Third-party tools like Greenshot or Skitch offer more annotation options if built-in tools are limited.
Verify the Fix
Confirm everything is fully working before closing this guide.
- Confirm all annotations are visible and legible at 100% zoom on the final image.
- Verify the save did not overwrite the original if you need both versions.
