GUN to TIFF 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.
