About Check GZIP Compression
Check GZIP Compression is a no-nonsense utility for engineers and technical marketers. Verify GZIP or Brotli compression and see exactly how much you save. Give it your URL and it returns a metric breakdown — no sign-up, no ceremony.
Point it at any publicly reachable page and it fetches, parses and evaluates what a crawler would actually see — not what your CMS previews. That distinction matters: the gap between the two is where most developer problems hide.
Check GZIP Compression is free to use with no account required. Signing in adds saved history, favourites and higher daily limits, and unlocks the other 311 tools on the platform.
