🧩 打乱图片像素（随机混淆，可用种子还原）Mix Pixels in Image (Scramble & Unscramble)
随机打乱图片的像素：可打乱全部像素、只在小方块内打乱、打乱整行或整列，或像拼图一样打乱方块位置。使用种子数控制随机顺序，同一种子总是得到相同结果，勾选“还原”并输入同一种子即可把打乱后的 PNG 精确恢复成原图，可用来简单地遮挡图片内容。支持批量，图片只在浏览器本地处理。Scramble the pixels of an image: shuffle all pixels, shuffle only within small blocks, shuffle whole rows or columns, or swap square tiles around like a jigsaw. A seed number controls the random order, so the same seed always gives the same result; tick Unscramble and enter the same seed to restore a scrambled PNG to the exact original, which makes it a simple way to hide what a picture shows. Works in bulk, and images are processed locally in your browser.

如何使用「打乱图片像素（随机混淆，可用种子还原）」？How do I use the Mix Pixels in Image (Scramble & Unscramble) tool?
在「打乱图片像素（随机混淆，可用种子还原）」中，选择或拖入文件，按需设置「打乱方式」、「方块大小」、「种子」等选项，然后点击每个结果旁的「下载」按钮即可；有多个文件时也可以点「全部下载（ZIP）」一次打包下载。In the Mix Pixels in Image (Scramble & Unscramble): Choose or drop your files, set "Scramble", "Block size", "Seed", then click the Download button next to each result (with several files, "Download all (ZIP)" saves them together).
怎样把打乱的图片还原？How do I restore a scrambled image?
打开打乱后导出的 PNG，选择与打乱时相同的打乱方式、方块大小和种子，勾选“还原”，即可得到与原图逐像素一致的图片。三项设置中任何一项不同都无法还原。请务必使用 PNG：JPG 等有损格式或被聊天软件压缩过的图片，像素值已经改变，无法精确还原。Open the scrambled PNG, choose the same scramble mode, block size and seed that were used, and tick Unscramble to get back an image identical to the original, pixel for pixel. If any of those three settings differs, it won't restore. Always use PNG: with JPG or other lossy formats, or images recompressed by chat apps, the pixel values have changed and exact restoration isn't possible.
这能用来加密图片吗？Can I use this to encrypt pictures?
它只适合简单遮挡（例如防止图片被一眼看到或被自动识别），不是真正的加密：种子范围有限，打乱整行 / 整列或方块位置时内容仍可能被猜出来。需要保密的图片请使用专门的加密工具。It's fine for casual hiding (so a picture can't be seen at a glance or picked up by automatic scanning), but it isn't real encryption. The seed range is limited, and with row, column or tile scrambling the content may still be guessable. For truly private images, use a proper encryption tool.
几种打乱方式有什么区别？How do the scramble modes differ?
“全部像素”把所有像素随机交换，结果像彩色噪点；“方块内的像素”只在每个小方块内部打乱，远看仍能认出轮廓，方块越小越清晰；“方块位置”像拼图一样整块交换（不足一块的边缘保持原位）；“整行 / 整列”交换整条像素线，得到条纹状效果。所有方式都只移动像素，颜色组成完全不变。All pixels swaps every pixel at random and looks like coloured noise. Pixels within blocks only shuffles inside each small block, so outlines are still recognisable from a distance, more so with smaller blocks. Tile positions swaps whole squares like a jigsaw (partial tiles at the edges stay put). Whole rows / columns swaps entire lines of pixels for a striped look. Every mode only moves pixels, so the colours themselves don't change.
有哪些选项可以调整？What options can I adjust?
「打乱图片像素（随机混淆，可用种子还原）」的设置：「打乱方式」可选 全部像素、方块内的像素、方块位置（拼图）、整行、整列（默认 全部像素）；「方块大小」默认 16，范围 2–1024；「种子」默认 2026，范围 0–999999999；可勾选：「还原（用同一种子反向打乱）」；可选文件：常见图片格式（含 HEIC、HEIF、AVIF、WEBP、BMP、JFIF）。改动任一选项后结果会按新设置重新生成。Settings in the Mix Pixels in Image (Scramble & Unscramble) — "Scramble": All pixels, Pixels within blocks, Tile positions (jigsaw), Whole rows, Whole columns (default All pixels); "Block size" default 16, range 2–1024; "Seed" default 2026, range 0–999999999; tick boxes: "Unscramble (reverse with the same seed)"; files: common image formats (including HEIC, HEIF, AVIF, WEBP, BMP, JFIF). Changing any option regenerates the result with the new setting.
