ISM to BPG Conversion: FAQ

What are ISM files?

ISM files are associated with Image System and they most likely contain a bitmap image that was created a long time ago. A similar image format associated with Image System is ISH, which contains high-resolution images, while ISM contains multicolor images. Opening both formats might pose difficulties when using a regular image viewer, so converting them to more accessible formats is probably the best solution for easier opening and transferring.

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.
