关于现代化 WebP 格式与图片优化
WebP 是由 Google 推出的一种支持有损与无损压缩的高现代图像格式。在与同等视觉质量的 JPEG 相比，WebP 可以减少约 25%~34% 的文件大小；相比 PNG 则可缩小约 26% 的体积，同时还能完美保留 Alpha 透明通道。
为什么不用担心服务器保存您的照片？
绝大多数商业压缩网站要求把照片上传到它们的后端转码，这带来了个人隐私与敏感凭证泄露的风险。JXDU 图片工具基于本地 HTML5 Canvas 与 FileReader 技术，所有压缩与转码操作都在您的设备内存中瞬时完成，连离线断网状态下也能使用。

Why You Never Have to Worry About Server Storage
Most commercial compression websites require uploading your private photos to remote servers for transcoding, introducing significant privacy risks.
