About DMG files

A .DMG file is an Apple Disk Image natively used by macOS to distribute software and store compressed files. When opened on a Mac, it acts exactly like a physical disk using the Apple DiskImageMounter.

The biggest disadvantage of .DMG files is their operating system restriction. They are formatted with Apple-specific file systems (like HFS+ or APFS) and often use proprietary compression like zlib or LZFSE. Windows and Linux systems cannot open them natively. Installing heavy, paid third-party software like TransMac just to extract a single file is an annoying bottleneck for non-Mac users.

To access these files on Windows or Linux, you must convert the .DMG to a universal disk image format like ISO. If you only need the internal contents, extracting them to a standard ZIP archive is the most pragmatic choice. Drop your file here to analyze and convert it securely right in your browser - free, online, and without installing software.

Convert.Guru analyzes your DMG file, detects the exact format, and lets you read the text inside.
