Starting with WordPress 6.5, support for AVIF has been added – a modern image format that offers significant improvements in quality and compression compared to previous formats such as JPEG, PNG, and even WebP. AVIF images can be up to 50% smaller than JPEG while maintaining the same quality. AVIF images also support a wide color range (including HDR) and provide sharper images than JPEG, especially in areas with high detail. Therefore, switching to AVIF format for your images will likely improve your site’s performance and visitor experience. And do modern browsers support it? Yes, almost all of them.
