Mark up screenshots and photos with arrows, boxes, text and blur. Built for quick bug reports and design feedback. Nothing leaves your browser.

All drawing happens on a Canvas in your browser. Your image is never uploaded.

FAQ

Is my image uploaded?

No. Drawing happens directly on a Canvas in your browser tab. The original image and the annotated output never leave your device.

Can I blur out a face or sensitive info?

Yes. Pick the Blur tool, then drag a rectangle over the region. We mosaic-blur the pixels in that area at export time.

Will the export keep the original resolution?

Yes. We draw the annotations on top of your source image at its native resolution and export a PNG at the same dimensions.

Can I undo a mistake?

Yes — the Undo button (or Ctrl/Cmd+Z) removes the most recent annotation. There's no fixed cap; you can keep stepping back.

Why is text fixed in size?

Right now, yes — one comfortable default size. Drag-resizing text is on the roadmap.
