WebP vs AVIF vs JPG: Which Image Format is Right for You?
By Web Optimizer June 12, 2026 6 min read
Optimizing web pages requires a solid understanding of image formats. Let's compare the three heavyweights: JPG, WebP, and AVIF.
JPEG (Joint Photographic Experts Group)
The standard since the 90s. It supports high compatibility but does not support transparency or modern compression efficiency.
WebP
Developed by Google. It supports transparency, lossy/lossless modes, and yields files 25% smaller than JPG. WebP is now widely supported in almost all browsers.
AVIF
The new benchmark. It offers superior compression over WebP and supports HDR. However, it takes longer to encode and lacks universal software support.
Comparison Table
| Feature | JPG | WebP | AVIF |
|---|---|---|---|
| Relative Size | 100% | ~75% | ~45% |
| Transparency | No | Yes | Yes |
| Compatibility | 99.9% | 97% | 85% |
