工具介绍
九宫格发图的关键是每张的构图都能独立成立，切之前先想清楚主体落在哪一格。这里把原图按 2×2、3×3 或 4×4 等分，切完每张都能单独看和单独下。 A grid post works when each square holds up on its own, so decide where the subject lands before slicing. This splits the image evenly into 2×2, 3×3 or 4×4 and lets you inspect and download each piece separately.
切分在本地画布上完成，原图不会上传；透明背景会照原样保留，导出统一是 PNG，避免再压一次损失画质。 Slicing runs on a local canvas and the source never uploads; transparency is preserved and every tile is PNG so nothing is recompressed.

常见问题
能切成 5×5 吗？Can it split 5×5?
不能，只提供 2、3、4 三档，社交平台的九宫格以 3×3 为主。No — only 2, 3 and 4 are offered; social grids mostly use 3×3.
为什么每张尺寸差 1 像素？Why do tiles differ by a pixel?
原图宽高不能被整除时，边缘按像素取整分配，属正常现象。When the width or height does not divide evenly, edges absorb the rounding — that is expected.
下载全部没反应？Why does download all do nothing?
浏览器会拦截连续多文件下载，允许本站「下载多个文件」后重试，或逐张点。Browsers block bursts of downloads; allow multiple downloads for this site, or click each tile.
会压缩画质吗？Does it lose quality?
不会，切片直接由原图裁剪后导出 PNG，不做二次有损压缩。No — tiles are cropped straight from the source and exported as PNG with no lossy step.
