How to Convert a Toast File to ISO

Converting a Toast (.toast) file to an ISO (.iso) file can be done relatively easily. Toast files are disk image files created by Roxio Toast, a popular disc burning software for Mac. You can convert Toast files to ISO format using a few different methods:

Method 1: Rename the File Extension (Easiest)

Since Toast files are essentially ISO files with a different extension, you can often simply rename the file:

  1. Locate the Toast File: Find the .toast file on your computer.
  2. Rename the File Extension:
    • Right-click on the file and select Rename.
    • Change the extension from .toast to .iso. For example, filename.toast should be changed to filename.iso.
    • If you receive a warning about changing file extensions, confirm the change.
  3. Test the File: Try mounting or opening the renamed file to ensure it works correctly as an ISO file.

Method 2: Use Disk Utility on Mac

If renaming the extension doesn’t work, or if you prefer a more robust method, you can use Disk Utility on a Mac:

  1. Open Disk Utility: You can find it in Applications > Utilities.
  2. Mount the Toast File:
    • In Disk Utility, go to File > Open Disk Image and open your .toast file. It will mount on your desktop.
  3. Create an ISO File:
    • Select the mounted disk image in Disk Utility.
    • Go to File > New Image > Image from [Your Disk Name].
    • In the dialog box, choose “DVD/CD master” as the format and save. This will create a .cdr file.
  4. Change the File Extension:
    • Locate the .cdr file in Finder.
    • Rename the file extension from .cdr to .iso.
  5. Test the ISO File: As before, ensure the new ISO file works correctly.

Method 3: Use Conversion Software

You can also use third-party software to convert Toast files to ISO. There are several tools available that can perform this conversion:

  1. Download a Conversion Tool: Look for a software tool that supports converting .toast to .iso. Examples include AnyToISO (for Mac and Windows) or PowerISO (for Windows).
  2. Install and Open the Software: Follow the installation process and open the software.
  3. Convert the File:
  4. Save and Test the ISO File: Save the new ISO file and test it to ensure it operates correctly.


  • File Compatibility: Check whether the software you intend to use (e.g., a virtual drive or burning software) supports ISO files or if it specifically requires Toast format.
  • Data Verification: After conversion, it’s a good practice to verify that all data has been correctly transferred and is accessible.
  • Legal Considerations: Ensure that you legally own the content you are converting and that it complies with copyright laws.

By following these methods, you should be able to convert a Toast file to an ISO file on both Mac and Windows operating systems.
