SUL to BPG Conversion: FAQ

What are SUL files?

SUL is an old and obsolete image format file associated with GFA RayTrace — a program designed for Atari ST computers. The software was released in the late 1980s and allowed users to operate with 3D objects in an incipient stage, usually implying a lot of time for required calculations. SUL files are now considered rare, so opening them probably requires conversion.

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.
