Redact screenshots and photos entirely in your browser — the sensitive file is never uploaded. Draw a box over what should disappear; the redaction kernel (Kāra → WebAssembly) runs on your machine. Downloading re-encodes the image, which also strips EXIF/GPS metadata.
⚠ Blur and pixelate only degrade pixels — determined recovery attacks on weak mosaics exist. For text (keys, names, numbers) use the solid bar, which destroys the data.
Where's the upload? There isn't one — watch the Network tab stay
empty. Each redaction calls the Kāra process(op, w, h, x, y, rw, rh, s)
export; the result becomes the working image, so redactions accumulate.
