Gzip / Brotli壓縮測試工具
檢查某個URL是否以壓縮方式（gzip或brotli）提供回應。
如何使用本工具
- 1
Paste the full URL you want to check, including the https:// scheme.
- 2
Submit the form to have our server request that URL.
- 3
Read the result card: it shows the Content-Encoding value (such as gzip or br) and whether compression was detected.
- 4
Adjust your server configuration if the card reports no compression, then re-run the check.
什麼是Gzip / Brotli壓縮測試工具？
對於文字內容（HTML、CSS、JS、JSON），壓縮可將傳輸體積減小60%到80%。Brotli（於2015年推出）的表現優於gzip；現代伺服器同時支援兩者，並會根據Accept-Encoding請求標頭選擇最優方案。本工具會檢查你的伺服器是否設定正確。
常見使用場景
Confirm that a newly deployed Nginx or Apache config is actually emitting gzip or brotli on your homepage.
Verify a CDN such as Cloudflare or Fastly is compressing HTML responses at the edge.
Spot-check an API endpoint that returns large JSON to see whether it is being compressed in transit.
Diagnose a slow page by ruling compression in or out before digging into other performance causes.
Check whether a specific path (not just the root) is served compressed when rules differ per route.
Demonstrate to a client or teammate, with a shareable result, that their pages are or are not compressed.
