How to Convert DMG to ISO on Mac, Windows and Linux?

If you’re a Mac user, you may have come across DMG files and wondered what they are and how to open them. DMG files are disk images, which are a type of file that contains everything on a disk or drive. In other words, a DMG file is a snapshot of a drive or disk.

What’s ISO and DMG file?

An ISO file is a disk image of an optical disc, often a CD or DVD. They can be created using disc-authoring software, or by using the CD or DVD drive’s “disk copy” or “burn image” feature. ISO files can be used for storing backups of optical discs, or for distributing large files that would not fit on a single disc.

A DMG file is a container file used on Apple computers. DMG files can be used to store disk images, which are used by some software programs to deliver software over the Internet. They can also be used to store backup images of a computer’s hard drive.

Why You Need to Convert DMG to ISO?

There are a few reasons why someone might want to convert a DMG file to an ISO file.

1.The first reason is that ISO files can be easily mounted in Windows, while DMG files cannot.

2. One reason is that ISO files are a universal standard, so they can be opened on any computer, regardless of the operating system.

3. ISO files are typically smaller in size than DMG files, so they take up less space on a hard drive or other storage device.

4. ISO files can be easily mounted in a virtual drive, which can be convenient if you want to access the contents of the DMG file without having to actually convert it to another format. For example, you can burn an ISO file to a blank CD or DVD and it will be readable on any computer, whereas a DMG file can only be read by a computer that has the HFS+ file system.

5. ISO files are a lot easier to work with. For example, if you want to extract the contents of a DMG file, you have to use a special program like 7-Zip, whereas you can just open an ISO file in any zip file extractor.

One way is to use the built-in DiskImageMounter tool to first mount the DMG file, and then use the command prompt to convert it to an ISO. Another way is to use a third-party tool like PowerISO or DMG2IMG to directly convert the DMG file to an ISO file.

Here’s a step-by-step guide on how to convert DMG to ISO on Windows 10 using DiskImageMounter:

Step 3: Once the DMG file is mounted, you should see it appear as a new drive letter in File Explorer.

Step 4: Now open the command prompt and type the following command:

“C:UsersusernameAppDataLocalMicrosoftWindowsIMAPI2”

Replace “username” with your actual username.

Step 5: In the IMAPI2 window, go to the “Advanced” tab and select the “Enable CD Recording on this drive” option.

Step 6: Now go back to the command prompt and type the following command:

“hdiutil makehybrid -iso -joliet -o outputfile.iso inputfile.dmg”

Replace “outputfile.iso” with the name of the ISO file that you want to create, and replace “inputfile.dmg” with the name of the DMG file that you want to convert.

Step 7: Once the ISO file is created, you can burn it to a blank CD or DVD using your favorite CD/DVD burning software.
