What is a Page Size Checker?

A Page Size Checker is an essential SEO and web development tool that measures the total size of a webpage, including all its resources. Page size directly affects loading speed and user experience, which in turn impacts search engine rankings.

Why Should You Check Your Page Size?

How Does the Tool Work?

This tool sends a request to the provided URL and retrieves the size of the main HTML document by reading the Content-Length HTTP header when available. It estimates page size based on this information.

Example response header:
Content-Length: 102400 (which equals 100 KB)

Best Practices to Reduce Page Size

  1. Compress images using tools like WebP or optimized JPEG/PNG formats.
  2. Minify CSS, JavaScript, and HTML files.
  3. Use lazy loading for images and videos.
  4. Leverage browser caching and content delivery networks (CDNs).
  5. Avoid unnecessary plugins and heavy scripts.
