How to Convert DMG to ISO on Windows/Mac

“Can I create ISO image file out of DMG file on my Windows 10 computer? I have a software DMG file and would like to mount it for Windows computer. But the problem is that I can’t find a proper tool to do this. Can you convert DMG to ISO file on Windows/Mac computer? How to convert DMG to ISO file in detail? Thanks in advance.”

Windows and Mac computers use different types of disk image files. In the macOS environment, Apple uses DMG. On the other hand, Windows uses ISO, which is also compatible with the Linux environment. If you are looking for solutions to convert DMG to ISO file on Mac/Windows computer, this guide would be helpful to you. We will show you different DMG to ISO conversion solutions on different operating systems.

Part 1: What is DMG? Why We Need to Convert DMG to ISO?

What is DMG? Why should we convert DMG to ISO file? DMG is the short form for the term Disk Image file. It refers to a file format that creates a mountable disk image that is used in Mac computers. In simpler terms, it is the digital form of the physical disc. The DMG file stores compressed software installing tools for Mac. Therefore, when you download any Mac program online, the file downloaded is likely to be a DMG file.

A DMG file comprises of a raw block of data that is encrypted in various encryption methods and compressed through multiple compression algorithms as well. If you wish to protect a DMG file, you can always apply a password.


DMG files are usable only on Mac computers and hence not compatible with Windows operating systems. If you would like disk image files in your Windows computer, you must use ISO files, which use the International Organization for Standardization file format. ISO files are perfect at mounting disk image files in any Windows operating system, especially the most recent, Windows 8 and 10.

Some people use them to emulate DVDs, CD or other disk drives virtually. An ISO file also holds the disk images of operating systems such as Linux that you can copy in the USB drive or burn into a disk. It can further send Windows software installation files online. However, a binary package with the MSI installer is used to send the files.

Unlike DMG files, ISO files are compatible with Mac operating systems. On the other hand, the ISO format lacks features like compression algorithms and encryption methods. Meanwhile, ISO is also functional in Mac. Such compatibility makes ISO files, especially for software installation, better than DMG. This means that DMG to ISO conversion is inevitable.
