JPEG (Joint Photographic Experts Group) uses lossy compressed encoding and is best for photographs, web images, and social media where smaller file size matters more than perfect quality. AVIF (AV1 Image File Format) uses lossy or lossless encoding and excels at next-gen web images — royalty-free format with better compression than WebP and JPEG. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
AVIF offers 50% better compression than JPG at the same visual quality. Converting to AVIF reduces file sizes significantly while maintaining or improving image clarity — ideal for web performance.
You can adjust the AVIF compression quality from 1-100. Higher values preserve more detail but produce larger files. The default (80) provides a good balance of quality and size.
AVIF is more efficient than JPG, so you often get better quality at smaller file sizes. However, since JPG is lossy, the source quality limits the output. Very low-quality JPGs won't improve by converting.
Chrome, Firefox, Safari 16.4+, and Edge all support AVIF. For older browsers, provide a JPG fallback using the <picture> element.
