About the Page Size Checker
Measure the HTML size, compression and resource counts of a page. This free tool runs instantly in your browser and checks the live page or domain from our server. No account needed.
Why check HTML page size?
Large HTML documents take longer to download and parse, especially on mobile. Keeping HTML small, compressed (gzip or Brotli) and free of unnecessary inline code helps pages load faster and makes them easier for search engines to crawl.
