About DMG and 7Z

.dmgApple Disk Image

application/x-apple-diskimage

DMG is the standard disk image format used by macOS for software distribution. When opened, it mounts as a virtual drive containing application installers. DMG files support compression, encryption, and integrity verification.

.7z7-Zip Archive

application/x-7z-compressed

7Z is an open-source archive format using the LZMA and LZMA2 compression algorithms. It often achieves significantly smaller file sizes than ZIP or RAR. 7Z supports encryption, large files, and solid compression, making it popular for backups and software distribution.

Conversion Notes

Archive conversion re-compresses the contained files using the target format's algorithm. DMG and 7Z may use different compression methods — lossless in both cases for general archives — so the output file size will differ. Encrypted archives require the original password to extract before re-packaging. File timestamps and directory structure are preserved.
