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, but UnFox is a free archive extractor for Mac that handles it with drag and drop simplicity.

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.

Tip

LZ4 decompresses at over 4 GB per second on modern hardware, making TAR.LZ4 one of the fastest archive formats to extract.

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. TAR.ZSTD offers better compression ratios while maintaining fast extraction, and both formats are compared in extract TAR.ZSTD files on Mac. UnFox lists TAR.LZ4 among the supported archive formats it handles natively on macOS.

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. You can download UnFox for free from the Mac App Store to get started.

How Does TAR.LZ4 Compare to Other TAR Compression Formats?

LZ4 prioritizes decompression speed over compression ratio, which makes TAR.LZ4 ideal for workflows where extraction time matters more than file size. TAR.GZ produces smaller archives but decompresses more slowly. TAR.ZSTD sits between the two, offering better compression than LZ4 with decompression speeds that approach LZ4 on multi core systems. Plain TAR files contain no compression at all, and the base TAR format is explained in extract TAR files on Mac. Users working with many archive types on Mac can use the same UnFox drag and drop workflow for all of them, as described in the general guide on how to unzip files on Mac.

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.
