How to convert an IMG file to ISO using Mac OS X Disk Utility

Mon, 2011-08-22 00:14

If you are ever in a situation where you have an img (disk image) file, but you want it to be an ISO file so you can mount it rather than burn it, then we have something in common. I stumbled on a quick and easy process using the free Mac OS X Disk Utility (free if you have a Mac) and have created a quick video to demonstrate the steps. Check it out...

Update: Thanks to an anonymous commenter, the much simpler way to achieve the same results is to rename the file extension from img to iso. I just tested this and it appears to work. Who would have thought?

I can't believe this actually works, but after testing it out, it looks like it does. Thanks for the even faster process.

I am curious if there are any drawbacks of doing this though, since ISO files have the ISO9660 file system and IMG files are just a raw dump of files - http://en.wikipedia.org/wiki/ISO_image

Hi Adam, I can confirm you

Hi Adam, I can confirm you that by simply changing the file extension from .IMG to .ISO it works great. I've been using this simple method for a couple of years.

not necessarily

This method won't work with legacy archived images. I've tried it and all the other suggestions mentioned on the web I can find.
