Why Convert JPG to AVIF?
AVIF (AV1 Image File Format) achieves 40–60% smaller file sizes than JPEG at comparable visual quality. For photo-heavy websites, switching from JPG to AVIF can dramatically cut bandwidth usage and improve Core Web Vitals scores. AVIF is supported by Chrome, Firefox, Edge, Opera and Safari 16+.
JPG vs AVIF — File Size Comparison
| Scenario | JPEG | AVIF (est.) |
|---|---|---|
| Portrait photo (2MP) | ~800 KB | ~350–500 KB |
| Product image (1MP) | ~300 KB | ~120–180 KB |
| Thumbnail (100×100) | ~8 KB | ~3–5 KB |
Tips
For photographic images, quality 65–80% in AVIF is roughly equivalent to JPEG quality 85–95. Start at 75% and reduce if the file size is still too large for your needs. AVIF quality settings are not directly comparable to JPEG quality numbers.
