Compression tools

Compression reduces the size of data by finding repeated patterns. It is used everywhere: HTTP responses, backups, container images, and file archives. The choice of algorithm is a trade-off between speed and ratio.

GZIP

GZIP Compress

Compress text with GZIP and download the result, entirely in your browser.

GZIP Decompress

About compression tools

GZIP and DEFLATE are the oldest and most widely supported. They are fast enough for HTTP and universally available. Brotli, developed by Google, achieves roughly 20% better compression on web content and is supported by every modern browser.

Zstandard, developed by Facebook, is designed for speed. It compresses and decompresses faster than GZIP while producing smaller output. XZ and LZMA offer the best ratios at the cost of memory and time, and are used for software distribution.

Archives combine compression with a file listing. ZIP and TAR are the standard formats. ZIP is random-access (individual files can be extracted without decompressing everything), while TAR is stream-oriented and is usually paired with GZIP or Zstandard. This site can create and extract both.
