頁面大小分析器
測量任意頁面的HTML大小，並統計其樣式表、指令碼、圖片和iframe的數量。
如何使用本工具
- 1
Paste the full URL of a public page (starting with https://) into the input field.
- 2
Click Analyze to have the server fetch that page's HTML.
- 3
Read the result cards: HTML shows the document size in bytes, and the other cards show how many stylesheet links, external scripts, images, and iframes appear in the markup.
- 4
Try a competitor or a previous version of your own page and compare the numbers.
什麼是頁面大小分析器？
頁面體積直接影響載入時間。網頁的平均體積約為2MB；小於1MB的頁面感覺輕快，而大於3MB的頁面則顯得遲緩。本工具測量HTML的大小並統計外部資源的數量；它不會下載每一個資源（如需完整的瀑布流分析，請使用Lighthouse），但資源數量可以預測總體積。
常見使用場景
Quickly checking whether a landing page's HTML has bloated to an unusually large byte size before a launch.
Counting how many separate stylesheet and external script tags a page loads, to spot bundling or third-party-tag sprawl.
Comparing the resource counts of your page against a competitor's to see who ships a leaner front end.
Auditing how many img tags a content or product page renders when investigating layout shift or lazy-loading issues.
Spotting unexpected iframes (embeds, ad slots, trackers) injected into a page's markup.
Sanity-checking a CMS or build change by diffing the HTML size and tag counts before and after a deploy.
