An ISO image file contains everything that can be burnt into an optical disc, including the optical disc file system. Windows users with Windows 7 or later can easily mount ISO files in a virtual disk drive on their computers and access the content inside. You can get ISO files from CDs, DVDs, and Blu-ray. ISO files can store video, audio, image, data, and software. There are two common file extensions you might encounter, which are .img and .iso. According to Wikipedia, ISO files have a smaller size compared to raw disc files, for they store only the user data from each sector on an optical disc. But the quality of the file remains the same as the file from the original optical disc. This is important when storing your 4K video or lossless music. To get rid of the uneasiness of sharing ISO files, continue reading to see how to convert ISO to MKV losslessly.
