Is my screenshot uploaded anywhere?

No. Everything happens in your browser — nothing is uploaded, nothing is stored. Your screenshots never leave your device.

Is the redaction permanent?

Yes. When you download the image, the blurred or blocked pixels are permanently changed in the file. The original content cannot be recovered from the exported image.

Can I undo my changes?

Yes. You can undo up to 10 actions using Ctrl+Z (or Cmd+Z on Mac). You can also redo undone actions with Ctrl+Y.

Does it work offline?

Yes. Once the page loads, the entire tool works with your network disconnected. Try it — turn off your wi-fi and it still works.

What formats are supported?

Input: PNG, JPG, WebP. Output: PNG (lossless), JPG, and WebP. The exported image maintains the original resolution.
