DMG to TAR Converter
Processing entirely on your device — large files may take a moment.
DMG is macOS's disk image: a UDIF container that can hold an HFS+/APFS filesystem, compression and even encryption. Every Mac app download ships as one. TAR preserves the exact file tree and permissions that Linux tooling expects.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the DMG format
DMG is Apple's Universal Disk Image Format: a UDIF wrapper that can carry an HFS+ or APFS filesystem, ADC/LZFSE/ZLIB compression blocks, and optional AES encryption. It is the distribution vehicle of every macOS application — double-click, drag, done.
The format is officially undocumented, which makes cross-platform extraction historically painful; 7-Zip's decoder handles the common compressed variants, letting any OS pull the payload out and repackage it as a plain ZIP or TAR.
+ Strengths
- ✓Native macOS distribution standard
- ✓Supports compression and encryption
- ✓7-Zip reads the common variants in-browser
! Limitations
- −Unofficial format — exotic variants may fail
- −Encrypted DMGs need a password
- −APFS volumes are partial-support
About the TAR format
TAR (tape archive) is Unix's fifty-year-old answer to bundling: it concatenates files with headers into a single stream, preserving POSIX permissions, ownership and symlinks — but compressing nothing. It is the container half of the classic .tar.gz pairing and the native format of Linux source trees and backups.
Being pure bundling, TAR pairs with a compressor: gzip (the classic), bzip2, zstd. Alone, a TAR is the same size as its contents. Windows 10+ ships bsdtar, so even Windows can unpack it now — permissions aside, where NTFS has no room to be faithful.
+ Strengths
- ✓Preserves Unix permissions and symlinks
- ✓Streamable: works over pipes and tapes
- ✓The standard of Linux distribution and backup
! Limitations
- −No compression by itself
- −No built-in encryption
- −Permissions meaningless on Windows filesystems
Why convert DMG to TAR?
There is a concrete reason this conversion exists: Unofficial format — exotic variants may fail TAR sidesteps that — Preserves Unix permissions and symlinks If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this DMG to TAR converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for DMG to TAR?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the DMG file.
Are the files inside my DMG archive modified?
No. Contents are unpacked in memory and repacked into TAR byte-for-byte — the conversion changes the container, never the files inside it.
