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.
Convert JPG to AVIF when maximizing web performance, reducing storage costs, working with HDR content, or targeting modern Chrome and Safari users. AVIF supports wide color gamuts, high dynamic range, and transparency — features JPG simply cannot match.
As of 2024, AVIF is supported by Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Coverage is growing rapidly. For maximum compatibility, use AVIF with a JPG fallback via the HTML
Drag your JPG file into ImgSwift or click to select. Batch conversion of multiple JPGs is supported.
Choose AVIF as the output format. A quality of 70–80% in AVIF typically matches 90%+ JPG visually while being half the file size.
Save the AVIF file. Use it directly on your website with a JPG fallback for older browsers.
Yes, significantly. AVIF achieves 40–50% smaller files than JPG at equivalent quality. It also supports HDR, wide color gamut, and lossless compression — 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 JPEG fallback using the HTML
At a quality setting of 70–80, AVIF typically looks sharper than JPG at 90 while being much smaller. The compression algorithm is fundamentally more efficient than JPG.
AVIF is generally 20–30% smaller than WebP at the same quality. The trade-off is slower encoding time — AVIF takes more CPU to compress, but for web delivery the smaller size usually wins.
