In order to do this, we’re first going to convert the image to a format that’s a little more universal: ISO. We’re going to use dmg2img to convert the DMG to an ISO image. If you already have dmg2img, great. If not, install it using your distribution’s native package management system. Linux doesn’t like to mount compressed DMG images. To get around this little obstacle, we’ll use dmg2img (see below). Option 2: Use dmg2img for compressed images. So you have a DMG image that you can’t mount because it’s compressed. You’ve done “file compressedimage.dmg” and you got “compressedimage.dmg: bzip2 compressed data”. You can open dmg file, convert it to iso file, or burn it to a CD / DVD disc. To convert it to iso file, please follow the steps, Run PowerISO. Choose 'Tools Convert' Menu. PowerISO shows Image Converter dialog. Choose the source DMG file you want to convert. Set the output file format to iso file. Enter the output file path name.
Here are ways that you can convert dmg files toiso files on Mac OSX, Windows and Linux.
Before we start, let’s download a dmg file from the public domain. I found one on Apple’s article about The XMLHttpRequest Object website while I was learning Ajax and that can be downloaded from this link. This is just a 150KB dmg file and will be handy if you want to have something to test with while you’re following this tutorial.
How to convert dmg files toiso files on Mac
Method 1: Using the Mac terminal
1. Open a terminal window from Finder > Applications > Utilities > Terminal.
2. Assuming that you have a disk image called apple.dmg in the current directory, type
hdiutil convert apple.dmg -format UDTO -o apple.iso
3. This will actually create a file called image.iso.cdr in the current directory (even though we asked for the output to be image.iso). This file can be safely renamed to image.iso, copied to a Windows server or machine, and burned with your CD/DVD burner of choice.
Generally, the command hdiutil can be used this way:
hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile.iso
Method 2: Using DMGConverter (freeware)
1. DMGConverter is a disk image (.dmg, .cdr, .iso) creation and conversion tool which is simple and easy to use. It is a very useful tool for the collective processing of more than one file and every folder, and it can deal with all the fundamental processing with the drag & drop of the file/folder. For Mac Only.
How to convert dmg files toiso files on Windows
This is for Windows users who might have downloaded a dgm file and wondering how to extract the content, or not even knowing how and what to do with the dgm file. I’ve been there at a certain stage. the sharewares mentioned are fully functional and allows you to use the “convert dmgtoiso” function even when it’s not registered yet.
Method 1: Using MagicISO (shareware)
1. Download MagicISO, install and run program.
2. Click to open dmg file.
3. Click to open “Properties” dialogs.
4. Uncheck Apple HFS and Apple HFS+
5. Check “ISO 9660″ “Joliet” “UDF”
6. Click OK
7. Click to save as toiso image, or click to burn to CD/DVD without saving.
Method 2: Using UltraISO (shareware)
UltraISO basically does the same thing, but it can save you time from doing step 3 to 6 compared to method 1.
Alternative Solutions: dmg2iso (freeware) and isobuster (shareware)
I’ve heard and read that some people had been able to convert dmg files into iso files using dmg2iso (freeware). I’ve tried dmg2iso, converted my dmg file to iso without problem, but the converted iso file is corrupted and can’t be open by any tools (Daemon Tools, Alcohol, MagicISO, UltraISO and ISOBuster) that I’ve tested. It might work for you, but no guarantees.
ISOBuster is pretty similar to MagicISO and UltraISO. But too bad that the function to “convert dmgtoiso” is restricted and won’t be functional until you buy the software.

ISO disk images
ISO image represents data copy of CD/DVD/Blu-ray optical disc. The name ISO is taken from ISO 9660 file system that originated on CD-ROM discs. ISO images have commonly .iso file extension. This format is supported by various burning applications, optical disc emulators as well as compression utilities.
Many disc utilities and burning applications, like Nero Burning ROM, Alcohol 120%, CDRWIN, PowerISO, MagicISO, Apple Disk Utility use their own proprietary disc image file formats (NRG, MDF, BIN, DAA, UIF, DMG) that can be often opened and burned only in these applications.
However there exist many simple converting tools available on the Internet, which can help you to convert any of these formats to standard ISO image format.
