Learn what Brotli compression is, why it matters for text resources, and how to check a public website for Brotli support.
How to Check Brotli Compression on a Website
Brotli is a compression algorithm that can reduce the size of many text-based web resources before they are sent to a browser. It can be useful for HTML, CSS, and JavaScript, but the important question is whether the live endpoint actually returns Brotli for the request you care about.
How to run a check
- Copy a public HTTPS URL.
- Open Bagiqo's Brotli Checker.
- Enter the URL and review the result.
- Compare a representative page with important text assets when needed.
Why Brotli may not appear
The server or CDN may not have it enabled, the response may be excluded, or a proxy may alter delivery. A response that is already compressed may also use another approach. These are possibilities to investigate, not conclusions from one result.
Investigate responsibly
Start with the delivery layer serving the tested hostname. Review its documentation, identify the response type, make one controlled change, and test the same URL again. Compression does not replace good asset choices or a complete performance review.
