Convert DMG to ISO

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 18, 2026
QUICK ANSWER
Is it possible to convert DMG to ISO?
Yes - DMG converts to ISO.

On Windows, AnyToISO and DMG2ISO provide a GUI conversion. On macOS, Disk Utility converts the DMG to a DVD/CD master (.cdr) which is ISO-compatible and can be renamed to .iso. The conversion changes the container only - any Mac application inside the ISO still runs only on macOS.

Why convert DMG to ISO?

ISO is a generic disk image format accepted by virtual drive software, disc-burning tools, and bootable USB creators on all platforms. These tools often support ISO but not DMG, so converting makes the image usable without Mac-specific software.

Quality & what to watch

  • Converting the container does not change what runs inside - a Mac application extracted from the ISO still only runs on macOS.
  • Encrypted (AES) DMGs cannot be converted without the password.
  • macOS Disk Utility outputs a .cdr file; renaming it to .iso is safe as the raw format is ISO-compatible.
