LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed. It belongs to the LZ77 family of byte-oriented compression schemes.

The algorithm gives a slightly worse compression ratio than the LZO algorithm – which in turn is worse than algorithms like gzip. However, compression speeds are similar to LZO and several times faster than gzip while decompression speeds can be significantly faster than LZO.
