About WeChat Article Image Compressor / 关于本工具
WeChat's article editor displays body images at roughly 900 px wide, and the platform limits how large each inserted image can be. Uploading a giant 5 MB photo just makes the article slower to open on mobile data and risks hitting the per-image cap — without looking any better, since it's shown at 900 px anyway. This tool helps you size and compress images for that context: small enough to load instantly on a phone, sharp enough to read at the editor's display width.
公众号编辑器里正文图片大约以 900px 宽显示，平台也限制单张插入图片的大小。上传一张 5MB 的巨图，只会让文章在移动数据下打开更慢、还可能触及单图上限——而画面并不会更好，因为最终就是按 900px 显示。本工具帮你针对这个场景调整尺寸并压缩：小到在手机上秒开，又清晰到在编辑器显示宽度下清楚可读。
Keep articles snappy / 让文章更跟手
An article with a dozen heavy images can feel sluggish; compressing each one keeps the whole piece light and improves the reading experience, which matters for completion and shares. Long screenshots are an exception — for those, stitch first, then compress the single result.
一篇塞了十几张大图的文章会很卡；逐张压缩能让整篇保持轻量、改善阅读体验，这关系到读完率和转发。长截图是例外——先拼接成一张，再压缩这张结果即可。
