Compress or decompress LZ4 (.lz4) files up to 2 GiB in your browser.
Compression
Compression shrinks data by writing repeated patterns once. Each format makes a different trade between speed and size: LZ4 and Snappy favor speed, zstd and Brotli balance speed and ratio, and gzip is the one almost every system can read.
The codec tools compress and decompress single files and streams in gzip, zlib, raw DEFLATE, Brotli, Zstandard, LZ4, bzip2 and Snappy, for files up to 2 GiB in your browser.
For archives, the unzip and TAR tools list and extract the files inside a .zip or a .tar.gz, and the ZIP creator packs up to 5 files into one archive with an optional AES-256 password.
Tools marked Runs in your browser process your files on your own device.
