Paste a screenshot, point at things with arrows, boxes, text, and step numbers — and pixelate or black out the parts nobody else should see. Then copy it or download it, done.
Most screenshots need two things before they're ready to share: something that says "look here", and something that hides what others shouldn't see. This tool does both. Paste a screenshot straight from your clipboard, add arrows, boxes, highlights, text, and numbered steps to walk someone through a screen — and pixelate or black out the email addresses, API keys, account numbers, faces, and order IDs that have no business going to Slack, a bug report, or a public post. Then copy the result back to your clipboard or download a PNG.
Ctrl+Z / Ctrl+Y.The pixelate and blackout tools don't just draw on top of your image in a way that can be peeled back — the exported PNG is a flat image in which the hidden region simply does not contain the original pixels. This matters: people have leaked secrets by "hiding" them with a semi-transparent marker in other apps, or by cropping in formats that kept the full image. A word of practical advice that most tools won't give you: for genuinely sensitive text, prefer Blackout over Pixelate. A solid bar destroys the information completely, while heavy pixelation of known fonts has, in research settings, been partially reversed. Pixelate is great for de-emphasizing names in a casual screenshot; Blackout is for the API key.
Think about what's in the average screenshot you redact: it's sensitive by definition — that's why you're redacting it. Uploading it to a random "photo editor" site so their server can blur it is exactly backwards. This tool runs entirely on your device: the image goes from your clipboard to your screen, every edit happens in your browser's memory, and the only copy that ever exists is the one you choose to save. Nothing is uploaded, logged, or retained — close the tab and it's gone.
Paste the screenshot with Ctrl+V, pick the arrow, box, highlight, or text tool, and mark it up. Numbered step badges place themselves in sequence, which turns any screenshot into instructions.
Use the redaction tools: pixelation or a blackout bar, both baked permanently into the exported pixels rather than layered on top, so the API key or account number cannot be recovered from the file.
Yes, Ctrl+V drops it straight onto the canvas, and when finished you can copy the result back to the clipboard just as fast: screenshot to annotated screenshot without touching a file.

No. Everything happens in your browser, which is rather the point when the screenshot shows your dashboard, inbox, or codebase.
