What is Page Size Checker?
A page size checker fetches a webpage and measures the raw HTML document size in kilobytes and the server response time in milliseconds. Large HTML pages slow down both user loading and Googlebot crawling — Google has a crawl budget for each site, and oversized pages consume it faster. Our tool also counts images to identify pages that may need lazy loading.
