About this tool
The AVIF Converter converts images to the AV1 Image File Format — the most efficient modern image codec, delivering 30–50% smaller files than JPEG at the same visual quality. Upload any image and get a web-optimized AVIF in seconds.
AVIF is now supported in all major browsers, making it the best choice for hero images and photo-heavy pages where every kilobyte counts toward load time and Core Web Vitals scores.
