JPG vs AVIF — Compression Comparison
Here's what you can expect when converting from JPG to AVIF at equivalent visual quality.
| Image Type | Typical JPG Size | AVIF Size | Reduction |
|---|---|---|---|
| Product photo (white background) | 250 KB | 80-120 KB | 50-68% |
| Landscape photograph | 400 KB | 150-200 KB | 50-62% |
| Portrait / headshot | 300 KB | 100-150 KB | 50-67% |
| Screenshot with text | 200 KB | 100-130 KB | 35-50% |
| Infographic / graphic-heavy | 350 KB | 150-200 KB | 43-57% |
| Thumbnail (small image) | 30 KB | 15-20 KB | 33-50% |
Photographic images with smooth gradients see the biggest file size reductions (50-68%). Images with lots of text, sharp edges, or flat colors see smaller but still significant improvements (35-50%).
Why Convert JPG to AVIF?
Page speed directly impacts user experience, conversion rates, and search engine rankings. Google uses Core Web Vitals — including Largest Contentful Paint (LCP) — as ranking factors. Images typically account for 50-70% of a page's total weight, making image optimization one of the highest-impact improvements you can make.
AVIF compression produces files approximately 50% smaller than JPG at the same visual quality. For a website with 20 images averaging 200 KB each (4 MB total), converting to AVIF reduces that to roughly 2 MB — cutting page load time significantly.
The savings compound at scale. An e-commerce site with 10,000 product images saves terabytes of bandwidth monthly by serving AVIF. A blog with image-heavy articles loads noticeably faster. Any website where images are a significant portion of page weight benefits from AVIF conversion.
AVIF is now supported by all major browsers: Chrome (since version 85), Firefox (93), and Safari (16). With over 95% of web users on supported browsers, AVIF is ready for production use with a JPG fallback for the remaining edge cases.
