Annotate a screenshot

Add arrows, text and boxes to a screenshot, and blur out anything sensitive, then export — all locally in your browser. No accounts, no uploads.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

Paste, mark up, paste back

The fastest screenshot workflow skips files entirely: hit PrtScn, paste straight into the editor with Ctrl+V, annotate, then copy the result back to the clipboard for your bug report, chat or doc. No temp files, no upload dialog — screenshots often show internal tools and personal data, and here they never leave the browser tab.

The full markup kit in one place

Arrows and boxes to point at the issue, text for the explanation, highlight for the relevant log line — plus blur and pixelate for names, emails and tokens that shouldn’t travel with the report. Crop off the irrelevant desktop, then export or copy. Undo covers every step.

Frequently asked questions

Is my image uploaded?
No. Every edit is applied on a canvas in your browser; your image is never sent anywhere.
What editing can I do?
Crop, rotate 90° left/right, flip horizontally or vertically, and add text (with font, color and size), arrows, boxes, ellipses and highlights. You can also blur or pixelate regions.
Can I hide sensitive information?
Yes. Use the Blur or Pixelate tools to permanently obscure faces, personal details or private data before sharing.
Can I move and edit things after adding them?
Yes. Switch to Select to move, resize or recolor any annotation; double-click text to edit it. Ctrl+Z / Ctrl+Shift+Z undo and redo, including crops and rotations.
Which formats can I export?
PNG (lossless, keeps transparency) or JPG.
