If you’ve recently switched from a Mac computer to a Windows PC, you may have found that some of your old files are no longer compatible. DMG files, in particular, can only be opened on a Mac computer. However, there is a solution – converting DMG to ISO. 

In this guide, we’ll walk you through the step-by-step process on how to convert DMG files to ISO in Windows 11/10. So, whether you need to access an old file or simply want to make your files more accessible across multiple platforms, this guide will come in handy!

What are DMG and ISO

DMG is a file format used in Mac computers that creates a mountable disk image and stores compressed software installing tools. DMG files are encrypted and compressed and can be password-protected. They are not compatible with Windows operating systems. 

ISO, on the other hand, is an International Organization for Standardization file format that can be used to mount disk image files in any Windows operating system and is compatible with Mac operating systems as well. ISO files lack features like compression algorithms and encryption methods, but they can hold disk images of operating systems and can send Windows software installation files online. Since ISO files are compatible with Mac and Windows, it’s often recommendable to convert DMG into ISO.

How to convert DMG to ISO on Your Windows PC

There are two basically methods to convert DMG to ISO which are as follows:

1. Convert DMG to ISO using GUI-based converter software
