Why Convert JPEG to AVIF?
AVIF is the most efficient image format available today, developed by the Alliance for Open Media (Google, Apple, Microsoft, Netflix). It delivers dramatically smaller files than JPEG:
| Image Type | JPEG Size | AVIF Size | Savings |
|---|---|---|---|
| 12MP photo | 3.5MB | 1.2MB | 66% smaller |
| Product image | 500KB | 150KB | 70% smaller |
| Blog header | 200KB | 60KB | 70% smaller |
| Thumbnail | 50KB | 15KB | 70% smaller |
Competitors like quicktoolify.com claims "up to 90% size reduction." webby.tools reports "AVIF is typically 40-60% smaller than JPG at equivalent visual quality" with support in "Chrome 85+, Firefox 93+, Safari 16+, Edge 121+." pngtoavif.com calls AVIF "the next-generation image format revolutionizing web performance."
