HTML Size Checker

Check if your page's HTML exceeds Google's 2 MB crawl processing limit. Google can download up to 15 MB but only indexes the first 2 MB of uncompressed HTML.

What is Google's 2 MB HTML Limit?

Google can download files up to 15 MB, but it only processes the first 2 MB of uncompressed HTML for indexing. Content beyond the 2 MB boundary may be ignored entirely — meaning important text, links, and structured data could be invisible to Google's index.

Why JavaScript Makes This Worse

If your site relies on client-side JavaScript to render content, the initial HTML document is often just a shell with <script> tags. Google will first download this HTML, then separately render the JavaScript. But some AI search engines (like Perplexity) don't render JavaScript at all — they only see the raw HTML.

How to Reduce HTML Size

  • 1. Move inline CSS/JS to external files — Large inline styles and scripts bloat the HTML document
  • 2. Paginate long content — Break extremely long articles into multiple pages
  • 3. Remove unnecessary HTML comments — CMS-generated comments can add kilobytes
  • 4. Use server-side rendering — Ensure critical content is in the HTML, not loaded via JS
