Converting a physical DVD into an ISO image file allows you to create an exact digital replica of your disc for backup, archival, or playback without a physical drive. Because operating systems like Windows and macOS do not offer a direct, one-click native button to create an ISO straight from a DVD, you generally need to use lightweight software.
Below is the step-by-step guide to converting a DVD to an ISO across different operating systems. Method 1: Using Windows (Free Software)
The most reliable and completely free utility for Windows is ImgBurn or AnyBurn. Insert your DVD into your computer’s optical drive.
Download and launch a trusted free utility like AnyBurn or ImgBurn.
Select the tool mode: Click on “Copy disc to image file” (or “Create image file from disc”).
Choose your source drive from the drop-down menu where your DVD is located.
Set the output destination: Click the folder icon, choose where to save the file, name your file, and ensure the file type is set to Standard ISO Image (*.iso).
Start the conversion: Click “Create Now” or “Read”. The process typically takes 5 to 15 minutes depending on your drive speed and the DVD size. Method 2: Using macOS (Native + Terminal)
Mac users can accomplish this using the built-in Disk Utility app combined with a quick Terminal command to change the file format.
Insert the DVD into your Mac-compatible external optical drive.
Open Disk Utility via Spotlight or by navigating to Applications > Utilities.
Select the DVD volume name from the left-hand sidebar (choose the inner volume name, not the hardware drive name).
Create a master image: Go to the top menu bar, click File > New Image > Image from [Your DVD Name].
Configure settings: Choose your save location, set the format dropdown to “CD/DVD master”, and leave encryption as “none”. Click Save.
Convert .cdr to .iso: Once finished, you will have a .cdr file. Open the Terminal app, type the following command, and hit Return:
hdiutil makehybrid -iso -joliet -o /path/to/destination.iso /path/to/source.cdr Use code with caution. Method 3: Using Linux (Command Line)
