Blur a face. Hide a plate.

No. Every patch is rendered on a canvas in your browser. Your photo never touches our servers — we don't run an image pipeline at all. Open DevTools → Network and watch: nothing leaves your device.

Blur looks softest and most editorial; works for faces in casual photos. Pixelate reads as deliberate stylization; popular for kids' faces and license plates. Solid bar is the strongest visual signal that something is being redacted; use it for legal/forensic contexts.

No. Each patch is rendered into the exported pixels — the original data underneath is replaced with the blurred/pixelated/blacked-out result. There's no metadata, no hidden layer. Once exported, the obscured area cannot be recovered.

For faces, a blur strength of 30–50px or pixel blocks of 30–60px is usually unrecognizable. For license plates, go higher — text shapes can be reconstructed from light blurs. When in doubt, increase strength and check from arm's length.

Yes. Click any empty area on the canvas to drop a new patch. Each patch has its own type, strength, position, and size. The side panel lists every patch — click to switch which one you're editing.

JPG at 92% quality and full source resolution. So a 4000×3000 phone photo exports at 4000×3000 with all the patches baked in. The result is a normal JPG that any app can open.

Pixelate at low block sizes (4–8px) and gentle blur (under 10px) can occasionally be reversed by adversaries with the right tools. For sensitive material, use solid black bars or bump strength to 40+.
