Quick Answer
This free online 10 minute timer counts down from 10 minutes with a repeating alarm and starts the moment the page opens. Timing uses your device's real clock, so the countdown stays exact even in a background tab. A ten-minute countdown fits short workouts, guided meditation, a pre-meeting prep block, or giving the kids ten more minutes at the park. Pause, resume, or extend any time — free, no sign-up.

Frequently Asked Questions
How do I set a timer for 10 minutes?
Just open this page — the 10 minute timer starts counting down immediately, no configuration needed. If you've paused or reset it, press Resume or Reset to begin the full 10-minute countdown again.
Will the alarm ring if I switch tabs?
Yes. The countdown is computed from real clock timestamps rather than counted ticks, so browser tab throttling cannot make it inaccurate — the digits snap to the true remaining time when you return. The alarm sound will play as long as you have clicked anywhere on the page at least once, because browsers require one user interaction before allowing audio.
Can I pause the timer and resume later?
Yes. Pause freezes the exact remaining milliseconds; Resume recalculates the end time from that remainder, so nothing is lost or drifted. You can also press +1 min at any point to extend the countdown, or Reset to start the full duration over.
What is a 10-minute timer used for?
A ten-minute countdown fits short workouts, guided meditation, a pre-meeting prep block, or giving the kids ten more minutes at the park.

Completely free with no sign-up, no ads on the timer itself, and no limits. Everything runs locally in your browser — the countdown and alarm keep working even after you go offline.
