PageUtil is a set of free online utilities for DNS, HTTP, text, encoding, and everyday calculations. Ben Fidge, a freelance developer based in Thailand, publishes the site. There is no company behind it, no team page, and no review program.
The tools are free. You do not need an account.
Most tools run in the browser. Passwords, tokens, and pasted text stay on the device. DNS lookup leaves the browser: it calls Cloudflare's public DNS-over-HTTPS resolver and does not follow CNAME targets.
A few checks call a Worker on this site. Those are a website status check, this connection's public IP and approximate location, Whois through RDAP, a TLS certificate check, HTTP headers, a redirect trace, and a single TCP port. The Worker does not store those checks and does not log them. Port Check tries one port. It is not a scanner.
