✦ Quick Answer

Why convert JPG to AVIF?

AVIF is the newest major image format for the web. Compared to standard JPEG, AVIF cuts file weight by 40% to 50% while maintaining sharp detail, smoother gradients, and higher dynamic range, dramatically boosting your Core Web Vitals (LCP) performance.

Next-Generation Image Optimization with AVIF

The AV1 Image File Format (AVIF) represents the next leap in web media optimization. Created by the Alliance for Open Media (AOMedia)—consisting of Google, Apple, Microsoft, Mozilla, and Netflix—AVIF applies modern AV1 video codec intra-frame compression to still photographs.

Converting your JPG photographs to AVIF allows you to achieve superior compression ratios without the color banding, blocking, or blurriness typical of high-compression JPEGs.
