Dmg Img
DMGExtractor is a Java-based application for extracting and converting Mac OS X dmg (Disk Image) file content into widely used image file formats, such as, BIN, ISO, and IMG. According to the developer, it is capable of manipulating CUDIFDiskImage based disk images while all other AES-128 encrypted disk images can also be handled. A dmg file extension is used for default disk image format in Mac OS X (macOS) that replaced the older IMG format. It is used much like ISO images on Windows platform. It is used much like ISO images on Windows platform.
What is DMG file
A DMG File stands for Disk Image file and it is a file format which is used to create mountable disks on the Macintosh operating system. The DMG File format contains data in the form of blocks which are often secured using encryption methods or are compressed using compression algorithms. DMG files are used for installing tools and softwares into the Mac OS operating system. The file is downloaded from the internet from the software manufacturer’s website and upon mounting the DMG file, a virtual disk is generated from where the user can either copy the application to the applications folder or run an installation script depending on the type of installation.
The newer disk image file was used in place of the original IMG or image file which was used in earlier versions of mac that are classic mac operating systems. Disk Image Files are only meant to be used in Mac based systems and not on the Windows operating systems. However, using some image softwares like Daemon tools on windows, we can mount disk images of DMG type on windows too. Some tools can also convert DMG Files to windows-recognizable image files like .ISO files.
Benefits of DMG Disk Image format
- DMG Images are read only which ensures that the files inside the installer are not altered with. This makes the software supplied inside the dmg secure from viruses as no one can alter the file after it is created.
- Instead of sending more than one file over the internet, the creators have to send a single dmg disk image which contains all the required installation files of the software that can be simply dragged and dropped into the applications folder of Mac to install them.
- DMG files can be customized according to the manufacturer’s wish so that the installers look pleasing when people download the files for installing software.
- Disk images can be mounted on a computer just like a physical cd. This is a good thing as people can save a copy of the DMG file as a backup which can be used later to restore the previous state of the files.
What is ISO File
An ISO file stands for International Organization for Standardization file format which specified ISO as the standard file format for disk image files in Windows. It is a file which can be used to mount disk image files in Windows operating systems. It can be used to emulate a CD, DVD or any other disk drive in Windows virtually.
It is generally used to hold disk images of operating systems like linux which can be burned into a disk or a USB drive. It is also used to send installation files of Windows softwares through the internet but they are usually sent through a binary package with an executable or an msi installer.
Basically ISO files are an image of something so you could have an image of a computer software package that would be all the files that existed on that computer software in one finite image. You can also burn that image file to a CD because these are optical images.
How to Convert DMG File to ISO
The ISO file format can be used on the Macintosh operating systems, however, almost all of the software packages for Mac is downloaded from the internet as a DMG Disk Image file. Although the DMG file format has some features which are not available in the ISO format like file encryption methods and compression algorithms, DMG files cannot be used anywhere else instead of a Mac. This is why we may need to convert DMG FIles to the ISO File format.

To convert dmg to iso file on Windows, you should install third party softwares like PowerISO. It is a disk image burning software that can be used to convert DMG File to ISO on Windows. You can also directly burn DMG Files to a CD/DVD using this software.
Before downloading PowerISO, check the system requirements that is required to install and run Power ISO.
System Requirements
- Any one of the following Windows Operating systems: Windows 98 / Windows Me/ Windows NT 4.0 / Windows 2000 / Windows XP / Windows 2003 / Windows Vista / Window 7 / Windows 8 / Windows 10 operating system or above.
- PowerISO can be used in both 32-bit and 64-bit versions of windows.
- Processor: Intel Pentium with 166 MHz clock speed or better.
- 64 Megabytes of RAM.
- A minimum of 128 Gigabytes of storage space is required to install and run PowerISO.
Steps to download PowerISO on Windows
- Visit the official website of the PowerISO.
- Go to the download section of the website
- Select the version 32 bit / 64 bit according to your computer.
- Click on download PowerISO 64 /32 bit
Now, an installer file will be downloaded on your computer, open the file and do the required steps to install PowerISO on your computer.
To convert DMG to ISO, first open the PowerISO application on Windows and then select the tools option from the top ribbon.
From the dropdown list, select the option labeled as convert. Now you will see a dialog box titled convert image file. You can use this to convert image files from one file format to another. In our case, we have to convert it from dmg file format to iso file format so we will set it up accordingly.
Now, we have to select a source image which will be your dmg file you want to convert. After that, select the destination image file and name it as the name of the iso file you want at the end. Below that, there is a drop down menu where you have to select the output file format, select iso file format there.
After that, there are image file settings options where you can password protect the images but since we are converting dmg file to iso, iso doesn’t have password protection options so that section is greyed out.
Now, select OK to start the conversion process. Wait for a few minutes for the conversion to complete. When the conversion is complete, you should get a message which says “Converting image file completes successfully”. If there is an error, check whether the input dmg file is corrupted or not. If there are no errors, go to the location of the output file you specified earlier, you should have an iso output file of the name you have given.
A DMG disk image file is Apple's container format for capturing entire drives or disks, similar to ISO for other platforms like Windows. It consists of data blocks that represent a physical disc. If you're on a Windows machine, you're limited in what you can do with DMG files. That's why you need third-party utilities to create a bootable DVD from DMG on Windows. This article explains two different methods to burn DMG files to amake bootable macOS installation DVD in Windows.
Method 1: How to Create Bootable DVD from DMG (Command Prompt)
This approach utilizes a tool called DMG2IMG, which converts DMG file into ISO, the universally more compatible archive format. This ISO file is then burned using a command line execution in Command Prompt. You don't really need any experience with disk images or command line work, but it will certainly help should something go wrong. If you're not comfortable with any of this, you can skip to Method 2, which showcases a powerful but user-friendly tool that does it all for you. But first, let's see how the Command Prompt method of creating a bootable DVD from DMG works.
Note: The older version of DMG2IMG is called DMG2ISO. Although the download is available in the link provided in Step 1 below, it is recommended that you use DMG2IMG instead. The utility has the ability to convert DMG into both ISO and IMG, based on your needs.
Step 1. Install DMG2IMG on a Windows PC after downloading the zipped win32 binary from this website. Unzip the file and run the .exe to install the program. You can also download DMG2ISO, but DMG2IMG is the recommended software to use.
Step 2. Open Command Prompt on your PC and execute the following command to convert your DMG into ISO. Be sure to change the file names as appropriate, and include the whole file path from the main directory:
dmg2img.exe c:downloadsexample.dmg c:downloadsexampleconverted.iso
Step 3. Now that your ISO file is ready, you can use the Windows ISO burning utility or a free application like FreeISOBurner to create a bootable DVD.
This DVD can be used to install macOS in virtual Windows environments with tools like Virtualbox. You can't use ISO files to install software in Mac, so if this is intended for a computer running Mac OS X or macOS, you will need to convert it back to DMG before you can install the program in question. If you're not confident that you can carry out the steps properly, then continue to Method 2.
Method 2: How to Make a Bootable DVD for Mac on Windows (DMGGeeker)
Conversion processes aren't always accurate and success rate is low for the first method. Many DVD are not able to be used to install macOS due to boot errors. Although DMG2IMG is a great tool, you may find that your resulting ISO file is corrupted and therefore useless. That means doing it all over again. Instead, you can try using DMGGeeker, which allows you to directly burn DMG to a DVD in Windows without having to convert the file. Such a disk can be used to boot a Mac computer.
DMGGeeker is an emerging star in the world of disk image file management software. It allows you to edit, add files to, delete content from, rename and do a lot more with DMG files on Windows without any conversion necessary. If you've been searching for the ideal DMG handling tool for Windows, your search has just ended. Let's see how the process works for creating a bootable media from DMG in Windows. It works with all recent versions of Windows.
Step 1Prepare for Installation
You can download it from the official site here. And then install DMGGeeker on a Windows PC.
