DMG (Disk iMaGe) is Apple's proprietary disk image format used primarily for distributing macOS applications and software installers. A DMG file is a mountable disk image that appears as a virtual drive when opened on macOS, typically containing a drag-to-install application bundle. DMG files can contain HFS+, APFS, or FAT32 formatted filesystems, and support optional zlib or bzip2 compression to reduce download sizes.

DMG images support several security and integrity features including optional AES-128 or AES-256 encryption, cryptographic checksums for verifying integrity, and code signing. macOS software distribution typically uses compressed DMG files (UDCO or UDBZ format) which mount as read-only volumes. The format also supports internet-enabled DMGs that automatically open their contents upon download.

DMG files are natively supported on macOS — double-clicking mounts the image as a virtual disk. On Linux, the dmg2img and hfsplus tools can extract DMG contents. On Windows, 7-Zip can extract some DMG files. The format is entirely macOS-centric and has no native support on Windows or Linux without third-party tools.

DMG is a macOS-specific format that other platforms cannot natively open. Converting DMG to ZIP or 7Z extracts the application files inside and makes them accessible across platforms, though macOS application bundles (.app) require macOS to run. LetsConvert handles DMG conversion to standard archive formats for content examination and cross-platform access.
