ISM to BMP 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 BMP files?

The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.
