When you hand off feedback on a design, words alone are slow: "the button near the top, no, the other one." Annotating the image directly — an arrow to the exact element, a box around the spacing issue, a note explaining the change — removes the ambiguity. A good image annotator turns a screenshot into clear, specific feedback in seconds.
This free tool runs entirely in your browser. Upload a mockup, a Figma export, or any screenshot and add arrows, rectangles, freehand pen strokes, and text labels in any color. Everything stays on your device — nothing is uploaded — and you can download the marked-up PNG to drop into Slack, a ticket, or an email. It is made for designers and reviewers who explain their work and want the feedback to be unmistakable.
Annotating a saved image is perfect for asynchronous feedback. But when you are presenting live — sharing your screen while you talk through a design — you want to draw on what is actually moving on screen, not a snapshot. That calls for a live, on-screen drawing overlay.
