Page Size Checker
Fetch a bounded HTML response and report transferred body bytes, Content-Length when present, and truncation status.
Uses a protected server check
Run the tool
Only public web targets are accepted. Private and reserved network ranges are blocked.
What this check means
This measures the fetched HTML response body, not the total browser page weight including every asset.
Because website responses can change by time, location, resolver, or server configuration, treat the result as a current observation of the submitted public target.
