About Annotate Image

Annotation turns a plain screenshot into clear communication. An arrow points to the button someone should click; a box highlights the error message; a line of text spells out the instruction. It's how you write bug reports, build quick tutorials, give design feedback, or explain "tap here, then here" without a paragraph of words. This tool layers arrows, rectangles and text directly onto your image so the meaning is obvious at a glance.

Make annotations readable

Use a color that stands out from the background — red or yellow on a mostly white UI, for instance — and keep arrows short and direct. One or two marks per image read better than a cluttered diagram; if you need to explain a long flow, use several images. Annotate before compressing, so the lines and text stay crisp rather than picking up compression artifacts.
