Sneaky Pixels Smuggles Pixel Art into QR Codes

Field notes

The generator accepts URL, text, Wi‑Fi, vCard, and email payloads, then exposes controls for error-correction levels, reserve headroom, symbol growth, mask optimization, contrast halos, and inversion behavior. Its sprite editor automatically adds a light halo around dark strokes, while the output can be downloaded as PNG or SVG. The page says payloads stay in the browser; only community sprites reach the server, and describes the encoder, decoder, and art-smuggling logic as hand-rolled.
