Countdown Timer

Countdown Timer - Free Online Timer with Alarm

Use our free Countdown Timer for cooking, studying, workouts, or any timed activity. Set custom durations or use quick presets from 1 to 60 minutes.

Set your desired duration using the hours, minutes, and seconds inputs, or click one of the quick preset buttons for common intervals like 5, 10, 15, or 30 minutes. Hit the start button to begin the countdown with a clear visual display showing remaining time. The timer runs in your browser tab with no server connection needed. Pause and resume anytime, or reset to your original duration instantly. When time expires, you'll receive both a visual alert and audio notification to ensure you don't miss the deadline.

Cooks time recipe steps precisely, from marinating meat for 30 minutes to baking cookies for exactly 12 minutes. Students use the Pomodoro-style intervals for focused study blocks followed by scheduled break periods. Fitness enthusiasts track rest intervals between workout sets or run timed HIIT training sessions. Presenters rehearse speeches within strict time limits to ensure they fit allocated conference slots without running over.

Keep the browser tab visible or at least unmuted to hear the alarm when time expires—many browsers pause background tab timers. Add a 30-second buffer to critical timings like cooking to account for your reaction time when the alarm sounds. Use multiple browser windows with different timers for complex workflows requiring overlapping time tracking. For long durations over an hour, verify your computer won't go to sleep and pause the countdown. Write down your timer settings before closing the browser if you need to recreate the same interval later.

All processing happens directly in your browser. Your files never leave your device — no server uploads, no cloud storage, no data retention. The tool works offline once loaded, requires no registration, and is completely free with no usage limits.
