Free Countdown Timer for Presentations & Keynotes
Keep your keynote, talk or panel on time with a giant countdown behind you. Project the timer on the main screen, drive it from your laptop with the mini remote, and use mirror mode for teleprompter setups. No signup, no install.
Why Speakers Choose FullScreenCountdown
Giant digits for the back row
Project on the main screen and the digits scale to fill it. Audiences in the back row read the time at a glance without straining.
Mini remote control
Drive the timer from your laptop while the projector shows the big countdown. Open the mini remote window and start, pause, or reset without breaking eye contact.
Mirror mode for teleprompters
If your speaker setup uses a half-silvered mirror for teleprompter reflection, enable Mirror Mode so the digits read correctly when reflected.
Auto-repeat for rehearsals
Practice your timing repeatedly with Auto-Repeat. The timer restarts itself after each run.
Audible alert, customisable
Pick a soft beep or louder alert. The bell rings only for the speaker when the timer hits zero, not before.
Share the URL with your AV team
Hand the timer URL to your AV crew so they can set it up on the venue projector before you arrive.

Frequently Asked Questions — Presentation Timer
Does the timer work on stage?
Yes. Press F to fullscreen. The digits scale to fill any screen — projector, LED wall, or smart TV.
Can I drive the timer from my laptop while it shows on the projector?
Yes. Open the mini remote control window from the Tools menu. It runs as a separate browser window and controls the main timer via localStorage events.
Does the mini remote need internet?
No. It runs entirely on your device using browser localStorage events. No server, no network required.
What is mirror mode?
Mirror mode flips the digits horizontally. It is designed for on-camera teleprompter setups where the timer reflects off a half-silvered mirror so the speaker can read it.
Can I share the timer with my AV team?
Yes. Just copy the URL. Every setting is encoded — duration, theme, autoplay, mirror — so anyone opening the link gets the exact same timer.
Can I run the timer through a confidence monitor?
Yes. Confidence monitors and stage displays are just regular screens. Open the timer fullscreen on the confidence monitor output.
