You don’t see it that often but the IMG format is widely used to distribute image files. For instance, Microsoft Office downloads are generally in IMG format.
While Windows 11 and 10 support the IMG file format natively, older versions of Windows, like 7 and 8, do not. Additionally, many popular applications like VirtualBox don’t support the IMG file format.
The good thing is that you can convert IMG to ISO with just a few clicks. Once you convert the IMG file to ISO file format, you can mount and open it in almost any application you want, including VirtualBox.
So, without further ado, follow these steps to convert IMG to ISO in Windows.

IMG vs. ISO file format
Both IMG and ISO file formats are used for disc images to create CDs or DVDs.
So, are IMG and ISO the same?
Though they are identical or near identical and serve the same purpose, there is one main difference between IMG and ISO. i.e., the way they store the data.
An IMG file is a raw image file that contains a copy of the data on a disc. It is not a standardized format, so the exact structure of the file may vary depending on the program used to create it.
On the other hand, ISO is an international standard file format for disc images. ISO files use the ISO-9660 file system, a standard format for data stored on CDs and DVDs. ISO files can be opened and used on a wide range of software and devices and can be used to create a new disc with the same data.
