How to Create an ISO Image

An ISO image is a file containing the exact content of a physical disk, like a DVD, CD, or even a USB drive. It enables easy storage, copying, and installation of software as a single file. This guide will walk you through a few simple and effective ways to create an ISO image.

What is an ISO Image and Why Do You Need It?

An ISO file is essentially a snapshot of a disk’s content packed into one file. It’s useful for backups, software distribution, or creating bootable USB drives. This image can be easily burned to a new disk or used with virtual machines.

Methods to Create an ISO Image

ImgBurn is one of the most popular tools for creating ISO images. This free program allows you to create disk images with just a few clicks. Here’s how to do it:

  • Download and install ImgBurn from the official website.

  • Select the source (the disk you want to create an image from) and specify a path to save the ISO file.
  • Click “Create,” and ImgBurn will start the ISO creation process.

2. Using CDBurnerXP

3. Creating an ISO in macOS with Disk Utility

Mac users can create ISO files using the built-in Disk Utility. This is a simple and fast way to create ISO images without third-party software:

  • Select the disk you want to convert to ISO.
  • In the top menu, choose “File” > “New Image” > “Image from [your disk].”
