AVIF vs WebP: Which Format for Your Web Performance Strategy?

In 2026, choosing an image format has become complex. WebP has won the war against JPEG, but AVIF is already knocking at the door. **WebP (The Current Standard)**: Supported by 97% of browsers, it's the safe choice. It reduces image weight by 30% without visible alpha loss. **AVIF (The Powerful Challenger)**: Based on the AV1 video codec, AVIF is the most efficient format in the world. At identical quality, it can be 20% lighter than WebP and 50% lighter than JPEG. It handles color gradients better and avoids 'banding' effects on skies or dark backgrounds. **The Technical Verdict**: For maximum performance, convert your images to AVIF with PulsConv. For users on old browsers, provide an automatic WebP fallback. This combination guarantees the best Google PageSpeed scores possible today.
