When to use which format

什么时候用哪种格式

JPEG is best for photos — many colors, smooth gradients. PNG is best for screenshots, line art, and anything with sharp edges or transparency. WebP often beats both, at the cost of slightly higher CPU on very old devices. Most modern browsers support all three.

JPEG 最适合照片 —— 颜色丰富、有平滑渐变。PNG 最适合截图、线稿以及任何需要清晰边缘或透明度的图像。WebP 通常在两种场景下都更好，代价是在非常老的设备上 CPU 开销略高。现代浏览器都支持这三种格式。
