免费 WebP 转换器
本地转换 WebP、JPG 和 PNG，适合网页图片、发布和交付前处理。
先在本地互转 WEBP、JPG、PNG，再上传、写文档或交付。
关于这个工具：免费 WebP 转换器
Convert images to or from WebP locally in the browser for smaller web assets and compatible downloads. 无需上传——全部处理都在你的浏览器本地完成，兼顾隐私与速度。
常见用法
- 想让网页图片更小，优先导出 WEBP。
- 旧应用或平台不支持 WebP 时，可以导出 JPG 或 PNG。
把图片转成 WebP 格式
在肉眼观感相同时，WebP 通常比 JPEG 小 25% 到 35%，而且支持 JPEG 没有的透明通道。让页面变快又不显得变差，靠的就是它。
把 WebP 用对
- 1
先调质量，再量体积
在几个质量档位上和原图比体积。最佳点通常比大家以为的更低。
- 2
除非确实需要，否则别做兜底图
现在主流浏览器都读 WebP。为几乎不存在的旧浏览器多存一份 JPEG，等于把存储翻倍。
- 3
透明图也用它
WebP 带 alpha 通道，体积只有 PNG 的一小部分，这正是它在网页图形上取代 PNG 的原因。
WebP 常见问题
- WebP 兼容性够吗？
- 在现行主流浏览器上完全够。「WebP 不兼容」这种说法已经是十年前的事了。
- 要透明用 WebP 还是 PNG？
- 给网页用 WebP，因为它小得多；需要精确像素或对方工具读不了 WebP 时才用 PNG。
- 转换要消耗积分吗？
- 不用。转换在浏览器本地完成，完全免费，也不消耗任何积分。
