在浏览器对比压缩前后的画质与体积，适合准备网页配图和投稿图片。
资源正文、示例和许可证保留原文。代码仅展示，不会在线执行或调用AI。
资源详情
适合图片太大、想减小文件体积但不想安装专业修图软件的人。它做图片压缩与格式转换，不负责生成图片；先保留原图，再导出副本。
使用前准备
- 适用平台
- 浏览器
- 内容更新
- 准备能运行 JavaScript 的现代浏览器和一份不含隐私的测试材料；首次无需安装编程环境。
- 准备一张自己有权使用的图片，先保留原件；普通压缩无需下载源码或模型。
从官方网页直接选图、对比、下载；不需要 npm 或其他安装命令。
常见卡点
- JPEG 不保留透明背景；小字截图过度压缩后可能难以阅读，先对照再下载。
- 官方 README 说明本机处理图片，也列出分析统计；不将本机处理解释为无网络请求。本站未实机压缩测试。
完整正文
【你能完成的小目标】把一张自己的照片压缩成更小的副本，比较清晰度是否仍然够用。
【开始前准备】用现代浏览器打开 https://squoosh.app ，无需先下载 GitHub 源码、Node.js 或模型。准备一张自己有权处理的图片，保留原件。
【第一次尝试】把图片拖进页面，在右侧选择输出格式和质量，拖动对比线检查文字、边缘和人脸。确认体积下降后，再下载结果；网页截图含小字时不要只追求最小体积。
【遇到问题先看这里】透明背景要选择支持透明度的格式，例如 PNG 或 WebP，JPEG 不保留透明度。尺寸和格式要符合最终上传网站的要求。官方 README 说明图片在本机浏览器处理，同时列出分析统计；本机处理不等于网站完全没有网络请求。旧开发分支快照仅供追溯许可，不推荐新手照其开发命令搭环境。

用一张自己的图片练习减小文件体积。这里的目标是“够清楚且更小”，不必追求最小数字。
打开网页并放入图片副本
从上方的官方入口打开 Squoosh，将一张有权处理的图片拖入页面，保留原文件。这个练习不需要下载源码、Node.js 或模型。
调一点质量，再对比
选择输出格式和质量，拖动对比线查看文字、人物和边缘是否明显变糊。需要透明背景时选择支持透明度的格式，例如 PNG 或 WebP。
下载并打开压缩后的图片
将结果下载成新文件，比较原图和新图的文件体积，再打开新图检查细节。若准备上传到某个网站，也核对它要求的尺寸和文件格式。
预期输出
得到一张体积比原图更小、关键文字和画面仍能看清的图片副本；原图继续保留。
2026-10-23 已阅读官方入口、固定提交 README 和完整许可证，按资料编写这个练习；本站未安装、操作或实测上游工具，界面与导出结果请在自己的设备核对。
适合用在哪里
- 准备网页或投稿配图
- 减小普通照片文件体积
注意事项
- JPEG 不支持透明背景，含小字截图过度压缩后可能难以辨认。
- 官方说明图片在浏览器本机处理，同时列出分析统计；不将其理解为网站没有网络请求。
