Arrows & boxes

Point at exactly what matters with a colored arrow or highlight box before sending a screenshot to a coworker.

🔒

Real pixelation

The blur tool permanently replaces pixels with a blocky downsampled version — not a translucent layer someone could remove.

Copy straight back out

Copy the edited image directly to your clipboard and paste it into Slack, email or a doc — no file needed.

Screenshot annotator FAQ

Is the blur actually removed from the file, or just drawn on top?

The blurred region is pixelated — the original pixels are permanently replaced with a downsampled blocky version on the same canvas, not covered by a layer. Once exported, the original detail is gone from the image data itself.

Can I paste a screenshot directly?

Yes — copy a screenshot to your clipboard and press Ctrl/Cmd+V anywhere on this page to load it instantly.

Is my image uploaded anywhere?

No — loading, editing and exporting all happen on an HTML canvas in your browser. Nothing is sent to a server.
