Arrow, text label, semi-transparent highlighter, and rectangle highlight box. Each tool's color and size can be freely adjusted.

Can I undo a mistake?

Can I change the font size and color?

Yes, both font size and text color are adjustable. The font family uses the system default.

Is the original image quality preserved?

Image Annotation Tips & Use Cases

Development & QA — Bug Reports

Mark up a screenshot with a red arrow and text label pointing to the bug location. Annotated images attached to Jira, GitHub Issues, or Slack dramatically reduce the back-and-forth needed to reproduce an issue.

Design Collaboration — Review Feedback

Draw arrows and add comments on specific design elements to give precise feedback — no more vague references like 'the button on the left.' Color-code by feedback type: green for approved, red for changes needed, blue for questions.

Tutorials & Documentation — Step-by-Step Guides

Add numbered arrows to software screenshots to guide readers to the exact click targets. Use the highlighter to emphasize important UI elements and improve readability in how-to guides.
