gz
What is a .gz file?
application/gzip
GZ is a file compressed with gzip, using the DEFLATE algorithm within a simple single-stream container that stores one compressed file plus a small header and checksum. It compresses a single stream rather than bundling multiple files. It is ubiquitous for compressing logs, tarballs, and HTTP responses.
How to use a .gz file
Use an example GZ to test gzip decompression, streaming inflate, checksum verification, and pipelines that transparently handle gzip-encoded content.

- GZ - Gzip Single FileA single text file compressed with gzip — the container-free codec on its own, for testing decompression and codec detection.
- GZ — Gzipped Float32 GLBThe float32 GLB from this group as a deterministic gzip stream (no embedded filename, mtime 0) — what a CDN actually sends when a viewer advertises `Accept-Encoding: gzip`. It compresses to 29.2% of its source against 55.6% for the quantized twin, which is the point of shipping both: quantisation halves the file on disk and then gives most of that back over the wire.
- GZ — Gzipped Quantized GLBThe quantized GLB from this group as a deterministic gzip stream (no embedded filename, mtime 0) — what a CDN actually sends when a viewer advertises `Accept-Encoding: gzip`. It compresses to 55.6% of its source against 29.2% for the float32 twin, which is the point of shipping both: quantisation halves the file on disk and then gives most of that back over the wire.
- Gzipped sitemap (500 URLs, .xml.gz)A 500-URL sitemap served the way large sites serve them - gzip-compressed as sitemap-large.xml.gz. The gzip header carries mtime 0 and no embedded filename, so the bytes are stable across regenerations. For testing that a crawler decompresses .xml.gz sitemaps before parsing.
