AVIF delivers roughly 50% smaller files than JPG at equivalent visual quality — the most dramatic compression improvement available today. For image-heavy websites, switching from JPG to AVIF can halve bandwidth costs and dramatically improve loading times, especially on mobile networks.
JPG (Joint Photographic Experts Group, introduced in 1992) uses DCT-based lossy (baseline, progressive, or lossless) compression. AVIF (AV1 Image File Format, introduced in 2019) uses AV1 intra-frame (lossy and lossless) compression. AVIF adds transparency support that JPG lacks, which is valuable for logos, icons, and overlay graphics. AVIF supports animation, unlike JPG. However, converting a static image will not create animation. JPG browser support: Universal. AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+).
The quality impact depends on the specific settings used during conversion. AVIF preserves full quality with lossless compression.
A 3 MB JPG photo at quality 85 typically converts to ~1.2-1.5 MB as AVIF at equivalent visual quality — a 50% reduction. For an e-commerce site with thousands of product images, this translates to terabytes of bandwidth savings per month.
AVIF encoding is significantly slower than JPG or WebP. Pre-generate AVIF images at build time rather than on-the-fly. Use the HTML <picture> element with AVIF as first source, WebP as second, and JPG as final fallback: this covers all browsers while delivering the smallest possible file to each.
