Understanding the technical differences between Google's WebP format and standard JPEG.
| Feature | WebP | JPG / JPEG |
|---|---|---|
| Compatibility | Modern web browsers & select image tools | 100% universal across all devices & software |
| Transparency (Alpha) | Supported (lossy & lossless) | Not supported (fills background with white/black) |
| Compression Ratio | 25–35% smaller than comparable JPG | Standard industry baseline |
| Animation | Supported (Animated WebP) | Static images only |
| Recommended Use | Web asset delivery & modern apps | Photo storage, print, emails & social sharing |
