# Sample ZSTD files for testing decompression, free and CC0 1 ZST test file of 239.3 KB. A direct URL, the file's SHA-256 and CC0, so curl and CI can fetch it with no signup and no keys. The page: . Zstandard is the modern compression stream: close to gzip's ratio at far higher speed, which is why it has spread quickly through storage systems, package managers and log pipelines. Like gzip it is a stream, not an archive; there is no entry list to enumerate. `zst/lorem-1mb.txt.zst` compresses exactly 1,000,000 bytes of Lorem Ipsum, so the ratio you measure is the one ordinary prose gives you rather than a figure distorted by random noise or padding. It is the newest of the four stream formats published here, and therefore the one your dependencies are most likely to lack: a runtime without zstd support fails in a different and usually less helpful way than one that simply cannot open a file. That is worth finding out deliberately rather than in production. Use it to test decompression, content-encoding negotiation and streaming readers.
