WebP vs AVIF in 2026: Which Image Format Should You Use?

In real-world tests with photographic images:

• At equivalent visual quality, AVIF files are typically 20–30% smaller than WebP.
• WebP shines at fast encoding — important for real-time image processing tools like PhotoResizer.us.
• AVIF excels with smooth gradients and skin tones, producing fewer banding artefacts.
• Both significantly outperform JPEG for photographic content.

• You need maximum browser compatibility.
• Your workflow requires fast encoding/decoding.
• You're serving images through a CDN that supports WebP natively.
• You're converting from JPEG and need a drop-in replacement.

• Maximum file size reduction is your priority.
• Your audience uses modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+).
• You're working with high-quality photography or HDR content.
• Encoding speed isn't critical (batch processing overnight).

Modern HTML gives you the <picture> element to serve the best format per browser:

<picture>
  <source srcset="image.avif" type="image/avif">
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="Description">
</picture>

This serves AVIF to browsers that support it, WebP as a fallback, and JPEG as the universal fallback.
