GUN to AVIF Conversion: FAQ

What are GUN files?

GUN is an image file format associated with Gunpaint, a currently obsolete drawing software program initially designed for Commodore 64 computers. This brand was highly popular in the 1980s and 1990s, being one of the first types of personal computers to become widely used by home users. The GUN format might also have been compatible with other models of 8-bit Commodore computers, such as the Commodore 16, 128 or SX-64. Images created with Gunpaint are most likely difficult to open using regular image viewers, so converting them is the best option.

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.
