AVIF to IFF Conversion: FAQ

What are AVIF files?

AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer.
