Why Convert JPG to AVIF?
AVIF uses the AV1 codec for dramatically better compression than JPG or even WebP. A 200KB JPG photo can become a 100KB AVIF with no visible quality difference. For websites, this means faster loads and better Core Web Vitals.
Browser Support Note
AVIF encoding in the browser works in Chrome and Edge. If your browser does not support AVIF output, the tool automatically falls back to WebP.
