Pick a tool – arrow, line, box, ellipse, highlighter, pen, text, numbered step, blur or callout – choose a colour and size and draw on the picture. Select marks to move, resize or delete them, use undo if needed, then save the image as PNG or JPG or copy it to the clipboard.
About the Image Annotator
The Img Stop Image Annotator is a quick mark-up editor for screenshots and photos. Point things out with arrows, frame them with boxes and ellipses, highlight text, number the steps of a guide with markers that count up by themselves, and add text labels or speech-bubble callouts.
Passwords, e-mail addresses and faces can be hidden with a pixelate, blur or black-bar box. Every mark stays editable – move it, drag its handles, change its colour or size – until you save. Everything happens in your browser, so confidential screenshots are never uploaded.
