Jiehunxiao: Reverse an Image-Scrambling Curve

jiehunxiao.net Visit website

Editorial interest 79/100 Selection signal · not a rating of the site

A browser-based tool that reorders pixels to reverse images scrambled with the Xiaofanqie method and related curve-based algorithms.

Landing page captured for the 2026-11-01 issue.

For: People with intact images scrambled by Xiaofanqie or similar methods
Worth noticing: It caps processing at 8 million pixels and 4,096 pixels per side, and handles only the first frame of GIFs.

Field notes

The page describes a workflow that uses an image’s original dimensions to determine its pixel mapping, with a comparison control and download step after processing. It lists several format-specific caveats: lossy JPG and WebP may retain positional alignment while changing colors, and GIF processing covers only the first frame. The site also cautions that pixel shuffling offers no cryptographic protection and recommends actual encryption for sensitive files.
