页面大小分析器
测量任意页面的HTML大小，并统计其样式表、脚本、图片和iframe的数量。
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.
什么是页面大小分析器？
页面体积直接影响加载时间。网页的平均体积约为2MB；小于1MB的页面感觉轻快，而大于3MB的页面则显得迟缓。本工具测量HTML的大小并统计外部资源的数量；它不会下载每一个资源（如需完整的瀑布流分析，请使用Lighthouse），但资源数量可以预测总体积。
常见使用场景
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.
