Convert JPG to AVIF online free. Reduce image file size by up to 50% vs JPG with superior quality. Next-gen format for modern websites. No upload.
AVIF is the next-generation image format developed by the Alliance for Open Media. It achieves file sizes up to 50% smaller than JPG at equivalent or better visual quality, outperforming even WebP in most tests. Switching to AVIF can dramatically improve page load speed and Google Core Web Vitals scores.
Drop your JPG or JPEG file into IMGVO. AVIF encoding runs entirely in your browser.
Default is quality 70 — visually excellent and dramatically smaller than JPG. Adjust to 80–90 for maximum quality.
Save the AVIF file and use it in your website with a <picture> element and JPG or WebP fallback.
| File size (same quality) | Baseline | 40–50% smaller |
| Visual quality | Good | Superior |
| Browser support | 100% | ~90% (Chrome, Firefox, Safari 16+) |
| HDR / wide color | ❌ No | ✅ Yes |
Yes, significantly. AVIF achieves 40–50% smaller files than JPG at equivalent quality. It also supports HDR, wide color gamut, and alpha transparency — none of which JPG supports.
Most modern browsers do. Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+ all support AVIF. For broad compatibility, pair AVIF with a WebP or JPG fallback using the <picture> element.
At a quality setting of 70–80, AVIF typically looks sharper than JPG at 90 while being much smaller. The compression algorithm is simply more efficient.
AVIF is generally 20–30% smaller than WebP at the same quality. The trade-off is slower encoding time — AVIF takes more CPU than WebP, though IMGVO handles this in the background.
