About Online Timer


Online Timer counts down a custom duration in the browser. You can pause or resume it, choose an alert, and use quick presets for common durations.

  • Enter hours, minutes, and seconds or choose a quick preset.
  • Select a sound, browser notification, or no alert.
  • Start the timer, then pause, resume, or reset it as needed.

Examples
