Image annotator
Open a picture, click a tool, and mark it up. Perfect for screenshots, instructions and feedback. The picture never leaves your device.
How to use
- Choose a picture (or press “Try a sample picture”).
- Pick a tool such as Arrow, Box or Text, then click or drag on the picture. Click an item to change its colour or move it.
- Press Download PNG. Your picture keeps its original size.

Everything happens in your browser: the picture is never uploaded. You can undo and redo any step, move and resize items with the round handles, change colours, and add numbered circles for step-by-step guides.
The optional AI command tab lets a chatbot place labels, arrows and boxes for you from a description. It can only add marks on top of your picture — it cannot see or change the picture itself.
Very large pictures are scaled down to at most 4096 pixels on the long side so the page stays responsive.
Frequently asked questions
Is my picture uploaded anywhere?
No. It is processed entirely in your browser and disappears when you close the page.
Can I add numbered steps?
Yes. Choose the Number tool and click where each step belongs; the numbers count up automatically.
Does the AI tab edit my photo?
No. It only places arrows, boxes and text on top. The original picture is untouched.
