Along with ISO format, IMG format is also widely used to distribute image files. For instance, Microsoft Office downloads are generally in the IMG format. Though Windows 10 supports IMG file format and even lets you mount the IMG file natively, older versions like Windows 7 have no support for IMG file format. Add to that, most applications won't support the IMG file format. For instance, you cannot mount an IMG file in VirtualBox. The good thing is, you can convert IMG to ISO with just a few clicks.
Once you convert IMG file to ISO file format, you can mount it in almost any application you want, including VirtualBox. So, without further ado, follow these steps to convert IMG to ISO in Windows.
