Convert your images to the modern AVIF format directly in your browser. AVIF (AV1 Image File Format) offers up to 50% better compression than JPEG and 20% better than WebP — same visual quality at significantly smaller file sizes. Perfect for web developers optimizing page load speed. All conversion happens client-side — your images never leave your device.
AVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG, PNG, and even WebP. A typical JPEG image can be reduced by 50-70% when converted to AVIF with no visible quality loss. This means faster page loads and lower bandwidth costs.
Simply drag your PNG files into the converter, set your desired quality (65 is recommended for web), and click Convert. The tool processes everything in your browser using WebAssembly — no upload needed. Download the resulting .avif files individually or as a ZIP.
