Florian Kastner writes: “JPG was developed to compress photos with lossy compression, which greatly reduced file sizes–a decisive advantage in the early days of the internet when storage space and bandwidth were still scarce resources. With the enormous progress in computer and software technology, the possibilities for image compression have also developed further. Today, modern image formats offer far better compression without compromising image quality. For many photographers, designers, and website operators, it’s becoming increasingly unattractive to rely on the outdated JPG format.” AVIF, JPEG XL, WebP, and HEIC/HEIF are likely to take its place.
