Checked

Where Chmod Calculator is better

  • The whole site is the calculator: nine checkboxes, two fields and a short explanation on one page, with nothing else to navigate.
  • The domain is the tool's name, so it's easy to type from memory.
  • It's plain HTML and jQuery and still ships shims for old Internet Explorer, so it works in very old browsers.

Where BrowserUtils is better

  • No third-party ads. Chmod-calculator.com runs two Google AdSense units.
  • One-click presets for common modes (755, 644, 600, 700, 777, 444), each labeled with what it's for.
  • Copy buttons for both the octal and the symbolic value.
  • Related server tools on the same site: a .htpasswd generator, a .htaccess generator and an nginx config generator.
