Quick Summary & Decision Matrix
Choosing between WebP, PNG, and JPG often creates confusion because each format was engineered for different eras and use cases:
- WebP: The modern web standard. Delivers 25% to 35% smaller files than JPG for photos and 35% to 52% smaller files than PNG for transparent graphics, with native support across all modern browsers.
- PNG: The lossless workhorse. Best for master logo files, graphic editing, icons, and diagrams where crisp edges and pixel perfection must be preserved across repeated saves.
- JPG / JPEG: The universal photo standard. Best for photographic images when compatibility with older photo viewers, desktop office applications, or legacy operating systems is mandatory.
