Nero is, without a doubt, one of the best burning software out there for Windows. While there are plenty of free alternatives to Nero, none of them offer all the features and options of Nero in a single application.
We all use Nero Burning ROM to burn discs, copy and backup disc images. By default, when you create an image backup of your CD or DVD, Nero Burning ROM saves the image in .NRG format. As many of the free CD/DVD burning software don’t support NRG file system, you have to convert the NRG image to the standard ISO file format before burning the ISO file to a CD/DVD.
Though there is an option present in the Nero Burning ROM to save a CD/DVD image in ISO format, most users end up saving in Nero image format as NRG is the default format. If you have one or more NRG disc images and want to convert them to the standard ISO format, you can now use a free tool named NRG2ISO for the job.
NRG2ISO, as the name suggests, is a simple tool for XP, Vista and Windows 7 to convert NRG files to ISO. The tool does its pretty well and does very fast too! In our test, it took approximately nine minutes to convert a 690 MB NRG disc image to ISO. Just input the NRG file that you want to covert by hitting the browse button on the right and then navigating to your NRG file location.
Once done, click Convert button to start converting your NRG file to ISO format. You can use free tools such as BurnAware or the native ISO burning feature present in Windows 7 to burn the ISO file to an optical disc. If you need a free tool to handle ISO files, we recommend you ISO Workshop, a free tool to convert ISO files and also to backup discs.
