•Transparency: No

•Animation: No

AVIF (AV1 Image File Format)

AVIF is a next-generation image format based on the AV1 video codec, offering exceptional compression efficiency that outperforms both JPEG and WebP.

•Compression: both lossy and lossless

•Transparency: Yes

•Animation: Yes

•Since: 2019

AV1 Image File Format supports transparency, but since High Efficiency Image Container doesn't include transparency data, your converted image will have a solid background.
