Official 7-Zip does not support LZ4 natively (only LZMA, LZMA2, PPMd, etc.). To add LZ4, you need a third-party build or use the 7-Zip ZS variant.

If you want, I can:
Looking at raw data points from compression benchmarks, LZ4 produces a compression ratio of roughly . However, its true value comes from the sheer speed: achieving around 422 MB/s for compression and an astonishing 1820 MB/s for decompression. By comparison, other fast algorithms like LZO (2.06 ratio) manage decompression of about 600 MB/s, making LZ4 nearly three times faster on the read side. : The modified builds scale dynamically across modern

Creating a basic LZ4 archive:
Your CPU usage will spike to 100% for a fraction of a second and then drop. The file compresses nearly as fast as copying the file to a second hard drive. : Windows users can install it instantly via
The is the most popular modded version. It acts as a drop-in replacement for the standard 7-Zip GUI. LZ4 Support: Includes LZ4 v1.10.0 .
While the official 7-Zip version is legendary for its LZMA and LZMA2 performance, it does not natively support the algorithm for creating or opening archives. To use LZ4 within the 7-Zip interface, you must use a "modded" or plugin-enhanced version. What is LZ4 and Why Use It?
For a folder containing 1000 small text files (logs or source code), a standard 7-Zip takes 3 seconds to compress. A modded 7-Zip with LZ4 takes . The archive will be larger, but the bottleneck shifts from the CPU to your SSD speed.
LZ4 is a lossless compression algorithm designed with a singular focus: . While LZMA2 might focus on shrinking a file to its absolute minimum size, LZ4 prioritizes how fast you can read and write that data.
