The only reason that someone would want to convert bin images to iso format is if the cue file of the bin image is missing.

Both formats, that is the iso and bin/cue format, are disk images that can be burned with virtually any CD or DVD burner and burning software.

The problem with bin formats is that they rely on cue files that tell the burning software how to burn the CD or DVD image to disc. If the cue file is missing the applications cannot find those information and refuse to burn the disc image.

WinBin2Iso is a tiny 43 Kilobyte application that can convert bin images without cue file to iso images which can be burned normally. Another option is Bin2Iso which has a size of only 12 Kilobyte and provides the same functionality.

Both applications convert the bin file to an iso file quickly. It usually does not take longer than a few minute to convert a full DVD image from bin to iso.
