ISS to BMP Conversion: FAQ

What are ISS files?

The ISS image format is considered rare and obsolete, and such files can only be opened using a limited number of image viewers. ISS files most likely contain bitmap images that were created or edited a long time ago. In case you have received such a file or found one on an old hard-drive, the best way to access its content is conversion to a better known format, such as JPEG or PNG.

What are BMP files?
