JPG vs WebP Format Guide
JPEG has been the web's standard photographic format for over 30 years, but its compression technology (DCT with Huffman coding) has not evolved significantly since its creation. While JPG quality remains acceptable, modern alternatives can achieve the same visual quality at smaller file sizes.
WebP, developed by Google, uses more advanced compression algorithms derived from the VP8 video codec. For lossy images, WebP produces files 25-35% smaller than JPEG at equivalent visual quality. WebP also supports transparency and animation — features JPEG lacks entirely.
Converting JPG to WebP is a best practice for web performance optimization. Smaller image files mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores — all of which directly impact SEO rankings and user experience.

Best Practices & Use Cases
Best Practices

- Serve WebP with a JPG fallback for the small percentage of browsers that don't support WebP
- Use WebP for all new web content — Google PageSpeed Insights specifically recommends next-gen formats
- Test visual quality at different compression levels, as WebP handles some image types differently than JPG
Common Use Cases
