Annotate Images for Tutorials & Feedback

A plain screenshot often isn't enough to explain a problem or demonstrate a feature.Annotating images with arrows, shapes, and text adds clarity and context. Whether you're creating a user guide, reporting a software bug, or just sharing a meme, our tool makes it easy to get your point across.

Essential Markup Tools

We provide everything you need to communicate clearly:

  • Arrows: Direct attention to specific buttons, errors, or details in your screenshot.
  • Boxes & Circles: Frame important areas without obscuring the content inside.
  • Highlighter: Add a transparent layer (like a yellow marker) to emphasize text or data.
  • Text Labels: Add step-by-step instructions or explanatory notes directly on the image.

Why Add Text & Arrows?

Visual communication is faster and more effective:

  • Bug Reports: Show developers exactly where the error is.
  • Tutorials: Guide users through a complex interface step-by-step.
  • Feedback: Mark up design mockups with specific changes.
