Image Annotation Tool

The image annotation tool helps you overlay visual notes on any image. Whether you need to point out UI elements on a screenshot, circle a bug in a design comp, label parts of a diagram, or highlight an area of interest on a photo, this tool provides all the essential drawing capabilities for everyday image markup tasks.

Choose from arrows, text labels, rectangles, circles, highlights, and straight lines, then drag on the image to place your annotation. Customize the color, stroke width, and font size to match your design or emphasis needs. The undo function lets you step back through changes without starting over, making it easy to refine your annotations until they are just right.

Since all processing happens in your browser, your images never leave your device — making it safe for confidential screenshots, internal documents, and sensitive visuals. The annotated image downloads as a PNG file, ready to paste into reports, share in chat, or embed in documentation. Perfect for creating quick visual guides, marking up design feedback, preparing training materials, and documenting bugs or issues.
