How to Extract TAR.LZ4 Files on Mac

UnFox extracts TAR.LZ4 archives on Mac by automatically decompressing the LZ4 layer and extracting the TAR contents in a single operation. TAR.LZ4 combines the TAR archiving format with LZ4 compression for extremely fast decompression speeds. macOS does not include native support for this compound format.

What Is a TAR.LZ4 File?

TAR.LZ4 files combine TAR archiving with LZ4 compression. TAR bundles multiple files into a single archive, and LZ4 compresses that bundle for reduced file size with minimal decompression overhead. The .tar.lz4 extension indicates this two layer format. LZ4 decompression runs at speeds exceeding 4 GB per second on modern hardware, making TAR.LZ4 one of the fastest compound archive formats to extract. These files appear in high performance computing, game development, and backup workflows.

How Do You Extract a TAR.LZ4 Archive on Mac?

Drag the .tar.lz4 file onto UnFox. The app detects the LZ4 compression header, decompresses the data, then parses and extracts the TAR contents. Both steps happen in a single seamless operation. UnFox displays a progress bar and the extracted file tree. No separate decompression step is required, and no Terminal commands are needed.

TAR.LZ4 is one of nine TAR variants UnFox supports, alongside TAR.GZ, TAR.BZ2, TAR.XZ, TAR.ZSTD, and more. all supported TAR variants and compression formats for Mac.

UnFox installs from the Mac App Store and handles TAR.LZ4 extraction without configuration. download UnFox free for Mac from the App Store.

Frequently Asked Questions

macOS does not support TAR.LZ4 natively. Archive Utility cannot decompress LZ4 data. UnFox or a command line tool like lz4 (via Homebrew) is required.
LZ4 decompresses significantly faster than gzip, making TAR.LZ4 archives faster to extract than TAR.GZ. The trade off is that TAR.LZ4 files are typically larger.
