Page Size Checker

Check your page size in seconds
Paste a URL and we'll tell you if the page is under Googlebot's 2MB HTML limit.

How this Page Size Checker works

  1. Paste a page URL.
  2. We load the page with Cloudflare Browser Rendering.
  3. We count HTML bytes and compare against Google's 2MB limit.
  4. You get a clear result: Pass, Warning, or Over Limit.

This checker focuses on Googlebot's web-search HTML guidance. PDF and broader crawler limits are separate.

Frequently asked questions

What does this tool check?
It loads the page in Cloudflare Browser Rendering, gets the final HTML, and measures its uncompressed byte size.
Why do you use a 2MB limit?
Google says Googlebot uses the first 2MB of supported web-search files. Content after that can be ignored for indexing.
What about 64MB and 15MB?
Google also documents 64MB for PDFs and 15MB as a broader crawler/fetcher default. This checker focuses on the 2MB web-search HTML case.
Will this always match raw server HTML size?
Not always. JavaScript can change the final HTML. Use this as a practical SEO check, not a perfect crawler simulator.
