How is screenshot annotation different from pro editing?

Quick mode has a minimal, ready-to-use UI focused on arrows/text/blur annotations; when you need pros like layers, masks and filters, switch to pro mode and continue on the same file seamlessly.

Does it work on mobile?

Yes. The UI is touch-adapted for mobile, so you can annotate screenshots right in a phone browser.

Do I need to sign up or pay?

No signup, free to use — annotate, copy and export without logging in.

No — annotation happens locally in your browser; images aren't uploaded.

Screenshot annotation

As simple as Excalidraw: add arrows, boxes, text, highlights and blur in seconds

Start annotating

Screenshot annotation is TutuDD's “quick mode”: built for everyday users — drop in a screenshot or image and add arrows, boxes, text, highlights and mosaic blur in seconds, then copy to the clipboard to paste back into chat or docs. As intuitive as Excalidraw.

Under the hood it shares the same engine as the pro editor: switch to “pro mode” anytime to keep refining with layers, masks and filters on the same file, seamlessly. All editing happens locally in your browser; images aren't uploaded.

Drag to draw — circle key points, point to spots, with double-headed arrows too.

Text / highlight

Click to type, and use the highlighter to mark what matters.
