中文介绍
把一张大图切成 3×3 九宫格，是发朋友圈、小红书多图笔记的经典玩法——一张照片拆成九块，点开是大图，列表里是九宫格，视觉冲击力强。
可自定义行数列数（最多 10×10），也可先自动裁成正方形再切。所有切片在你浏览器里生成，直接下载，图片不上传。
常见问题
为什么要点开才是完整大图？
平台列表缩略图会按九宫格排列，点开某块即进入原图的对应区域，视觉上是完整画面。切图后每块独立，可单独保存。
能切成别的格数吗？
可以。行列数 1-10 自由调整，比如 2×3、4×4。建议保持正方形裁剪，切片更整齐。
切图会原图上传吗？
不会。整张图在浏览器内存里处理，切片和原图都不上传，刷新即清空。
English
Splitting one image into a 3×3 grid is the classic trick for Moments and Xiaohongshu multi-image posts — one photo becomes nine tiles that look like a grid in the feed but open as a full image.
Custom rows/columns up to 10×10 are supported, and you can crop to a square first. Every tile is generated in your browser and downloaded directly — nothing is uploaded.
FAQ
Why does the full image only show when tapped?
The feed shows the tiles as a grid; tapping a tile opens the corresponding region of the original. Each tile is saved independently.
Can I use a different grid size?
Yes. Rows and columns are adjustable from 1-10, e.g. 2×3 or 4×4. Keeping the square crop makes tiles neater.
Is the original uploaded?
No. The whole image is processed in browser memory; neither the tiles nor the original are uploaded, and a refresh clears everything.
