About JPG
JPG (JPEG) is the most widely supported image format in the world. It uses lossy compression tuned for photographs, producing small files that look great for real-world scenes. It doesn't support transparency, so transparent areas are filled with a background color when converting to JPG.
About AVIF
AVIF is the newest mainstream image format, based on the AV1 video codec. It achieves the smallest file sizes of any widely supported format at comparable quality and supports transparency, animation and HDR. Browser support is now broad, but many apps and platforms still can't read or export it.
