如何免费压缩图片
选择一张或多张照片，拖动质量滑块，cutbg 会立即把它们重新编码成更小的文件，并实时显示压缩前后的体积。放入整批图片，然后全部打包成 zip 下载。
我的图片会被上传吗？
不会。压缩完全通过 Web Worker 在你的浏览器中运行，所以文件永远不会离开你的设备，也无需等待上传。

常见问题
- How much smaller can it make my image?
- Usually 40–80% smaller with no visible quality loss. Drag the quality slider to trade file size for fidelity.
- Does it support JPG, PNG and WebP?
- Yes, all three. The quality slider has the biggest effect on JPG and WebP; PNG shrinks mainly by resizing.
- Is compression private?
- Yes — it runs in your browser using a web worker, so your file is never uploaded.
