Sample ZSTD files for testing decompression — free, CC0

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. Related formats: GZIP, BZIP2, XZ and TAR.
