GUN to BPG 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 BPG files?

BPG is a new and promising image format, which currently provides the most advanced technology in image compression. Released in 2014 by software developer Fabrice Bellard, the BPG format has been shown to include the best quality/size ratio, when compared to other popular formats such as JPG or PNG. The number of image viewers that can open BPG files is currently limited, but is expected to grow in the near future. For easier access, conversion can be done to and from the BPG format.
