The Compression Analyzer by SeoPro.Tools lets you instantly verify whether HTTP compression (GZIP or Brotli) is active on any URL. Uncompressed responses can be 70–90% larger than necessary, slowing page loads and hurting your Core Web Vitals score.
Using the Compression Analyzer is straightforward. Enter any webpage or asset URL, click Analyze, and within seconds you get a clear report showing the compression method detected, the original versus compressed file size, and the percentage of savings achieved.
The tool is ideal for SEO professionals, web developers, and site owners who want to diagnose performance issues, audit third-party resources, or verify that server configuration changes have taken effect. No installation needed — run unlimited checks directly in your browser with SeoPro.Tools.
