Online Timer — Free Countdown Timer (1, 5, 10, 15, 30 Min)

Pick a preset (1 minute up to 1 hour) or enter your own hours, minutes, and seconds, then hit Start. The timer counts down with a live progress bar and plays an audible chime when it finishes.

• Pause & resume: pause anytime and pick up right where you left off; Reset returns to the full duration.
• Loop mode: tick the loop checkbox to restart the countdown automatically — handy for interval training, Pomodoro rounds, or kitchen routines.
• Alarm: the finish chime is generated with the Web Audio API, so it works offline with no audio files.
• Private: everything runs in your browser; no uploads, no accounts, nothing stored.

Tip: keep the tab open (or pinned) so your browser doesn't throttle the countdown in the background.
