如何使用「长图切割（切成多张 / 朋友圈九图）」？How do I use the Long Image Splitter?
选择一张长图，选择切割方式：发小红书选 3:4，手机全屏看选 9:16，也可以指定张数或每张高度。勾选“智能避开文字”，预览里红线就是切割位置，确认后点“下载全部（ZIP）”。Choose a long image and a split mode: 3:4 for Xiaohongshu, 9:16 for full-screen phones, or set a count or height. Keep “Avoid cutting text” on; red lines show the cuts. Then download all as ZIP.
怎么避免把文字切成两半？How do I avoid cutting through text?
勾选“智能避开文字（在空白处切）”，工具会在每条切割线附近寻找空白行下刀，每张高度会略有不同，但文字不会被切断。Tick “Avoid cutting text”; each cut moves to the nearest blank row, so heights vary slightly but no line is split.
和“图片切割（九宫格）”有什么区别？How is this different from the grid splitter?
九宫格切割是把一张图切成 3×3 等网格，适合拼成大图展示；长图切割是从上到下切成几段，适合把长截图拆成多张按顺序浏览。The grid splitter cuts an image into equal tiles (e.g. 3×3); this tool cuts a tall image top-to-bottom into pages read in order.
切出来的图片清晰吗？Are the pieces sharp?
切割不缩放图片，每张都保持原图的分辨率。导出 PNG 是无损的；JPG 默认高画质，文件更小。Cutting does not rescale, so every piece keeps the original resolution. PNG is lossless; JPG uses high quality for smaller files.
