- Its page warns that the method has no key and cannot protect sensitive information; it recommends opaque redaction instead.
Field notes
The page lays out a two-step permutation: pixels follow a Gilbert curve, then shift by a fixed offset calculated from image dimensions. Its interface includes file selection, paste, a sample image, and controls for scrambling, reversing, and downloading. The site recommends staying below 8 million pixels because browser memory can be a limit, and notes that semi-transparent edges may differ by ±1 after a round trip.
