The conversion of the file DMG to IMG will allow you to edit a file using other software than before. The conversion DMG to IMG is particularly helpful in cases where you want to give certain features to the data in the DMG file, and all the programs that support the DMG format do not have the possibility to introduce the desired changes.
Just download one of the programs from the list and install it on your computer. After starting the program, select DMG file that you want to convert. Then select the target format (in this case IMG) and follow the instructions. Save the converted IMG file in the selected location. From this moment you can open the IMG file with all the programs that you will find here.
