WebP is commonly used for modern websites, product images, and performance-focused pages, while AVIF is a better fit when you want very efficient compression for delivery to modern browsers and apps. Converting WebP can make the image easier to open in older software, although the output may be larger.
Understand the size and quality tradeoff
AVIF can produce small files, but encoding takes longer and support is weaker in older image editors and operating systems.
