Clarity, drawn directly on.
Explain visually
Annotate screenshots and images without opening a design app.
Add arrows, lines, rectangles, circles, freehand drawing, text callouts and numbered step markers to product screenshots, tutorials, bug reports and feedback images.
Annotations remain selectable and movable. Change their colour, stroke, opacity or text size, reorder overlapping items, undo and redo edits, or crop the image before export.
Download the final image as PNG, JPG or WebP, or copy it directly to the clipboard. Everything runs locally in your browser.
