Page Size Checker

0 out of 0 stars

The Page Size Checker downloads the HTML of the given URL and reports its size in kilobytes or megabytes. This helps you understand the initial weight of the page being loaded. While it doesn’t account for external resources like images and scripts (which also matter), a large HTML file alone can slow down rendering, especially on mobile devices. Use this tool to monitor code bloat, remove excessive markup, and keep pages lightweight. For a full analysis including all resources, try our more advanced SEO audit.
