MAC files can also be found under the PNTG extension on Mac computers and they are frequently used for clip art or monochrome graphics.

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.
