How to Add a Timer to PowerPoint (2 Easy Methods)

Method 1 — Overlay timer (recommended, works in Slide Show)

An overlay timer is a separate always-on-top window, so it survives full-screen Slide Show mode and you can reuse it for every presentation — including Google Slides and Canva. Unlike embedding a GIF or video into a slide or installing an add-in, SlideTimerApp is a separate overlay window — so it survives full-screen Slide Show, can be moved, resized and reset live, and is reused across every deck and every app. This is the method most speakers and teachers prefer.

1. Download and open SlideTimerApp. Get the free Windows app and run it. It's a ~3 MB portable file with no installation, so a transparent timer window appears the moment you open it.
2. Set your duration. Type the minutes and seconds you need, or tap a quick preset (1, 5, 10 or 15 minutes). You can also set the point where the number starts turning red so you get a visual warning as time runs low.
3. Pin it on top. Click the pin button so the timer stays above every window — including PowerPoint. Drag the timer to the corner you like and drag a corner to resize it; the digits scale with the window.
4. Start your Slide Show. Press F5 (or Slide Show ▸ From Beginning). The timer floats on top of your slides and counts down, then flashes and plays an alarm at zero. Press Space to start/pause and R to reset.

Why this works in full screen: because the timer is its own window — not an object placed inside a slide — PowerPoint can't cover it. The "always on top" setting keeps it above the Slide Show. The same overlay doubles as a general presentation and speech timer for any app you share on screen.

Method 2 — Insert a timer GIF or video into a slide

If you only need a fixed countdown on one slide and don't need to move it, you can embed a timer file:

1. Find a timer file. Get a countdown GIF or MP4 of the exact length you need (e.g. a 5-minute countdown).
2. Insert it. On the slide, go to Insert ▸ Video ▸ This Device (for MP4) or Insert ▸ Pictures (for GIF).
3. Set it to play automatically. For video, open the Playback tab and set Start: Automatically. Resize and position it on the slide.
4. Present. When you reach that slide in Slide Show, the countdown plays.

Limitations: the duration is fixed to the file, it only appears on that one slide, you can't move or reset it mid-talk, and you must re-insert it for every new deck. If you're weighing the trade-offs, our overlay vs GIF vs add-in comparison breaks down each option side by side.

Which method should you use?

Show the timer in Presenter View or on a second monitor

When you present with two screens, PowerPoint shows the slides full-screen on the projector or second monitor and gives you Presenter View (next slide, notes and a small built-in clock) on your laptop. Because SlideTimerApp is an independent window, you decide exactly which screen it lives on — just drag it there.

1. Extend your display. Press Windows + P and choose Extend so the two screens are separate desktops rather than mirrored.
2. Start the Slide Show. PowerPoint sends the slides to the audience screen and opens Presenter View on your laptop.
3. Place the overlay. Drag the SlideTimerApp window to the screen you want. Keep it on your laptop to make it a private cue, or drag it onto the audience screen to show a big visible countdown to the room.
4. Pin it. Make sure the pin (always-on-top) is on so the window stays above the full-screen show on whichever monitor it's on.

Tip: PowerPoint's Presenter View has its own small clock and an elapsed timer, but those are for you alone and can't be shown to the audience. The overlay is the only one of the two you can put on the big screen.

Keyboard shortcuts

You don't need to fiddle with buttons mid-talk. These controls work while the timer is on top of your live Slide Show:

Tip: Space and R also work in a classroom timer setup, so you can start and reset a task timer without looking away from your students.

Troubleshooting: the timer is hidden behind the slideshow

If your timer disappears the moment you press F5, it almost always comes down to one of three things:

1. The pin isn't on. The most common cause. Click the pin / always-on-top button in SlideTimerApp before you start the show. Without it, full-screen PowerPoint draws over the overlay.
2. The overlay is on the wrong screen. On a single-monitor setup the Slide Show fills the whole display; on dual monitors the overlay may be sitting on a screen you can't see. Exit the show with Esc, drag the timer onto your visible screen, then restart.
3. Presenter View vs a single screen. If you're mirroring (not extending), Presenter View can fight with the overlay. Switch to Extend with Windows + P, or turn Presenter View off (Slide Show ▸ untick Use Presenter View).

Still stuck? Alt + Tab back to SlideTimerApp, confirm the pin is lit, and place it where you want — the window will then stay above the show.

Common mistakes to avoid

• Embedding a GIF that can't be paused. A baked-in GIF or video keeps counting even if your Q&A runs long or you skip ahead — there's no pause or reset. An overlay you control live avoids this entirely.
• Forgetting to pin. If you skip the always-on-top toggle, the timer vanishes behind the Slide Show. Pin it before you present.
• Making the timer too small to read. From the back of a room, tiny digits are useless. Drag a corner to enlarge the window until the numbers are legible for your furthest viewer.
• Relying on an add-in you have to install. Add-ins need admin rights and re-installation on every machine. If you're tempted, read whether you actually need a PowerPoint timer add-in first — usually you don't.

Auto-advance slides and per-slide timers

Showing a countdown to your audience is different from making slides move on their own. Here are both, plus how to tie a timer to one specific slide.

Auto-advance every slide on a timer

To make slides advance automatically after a set time, go to the Transitions tab, tick Advance Slide ▸ After, enter the seconds, and click Apply To All. Every slide will now move on after that interval, with no clicking. This is great for a looping lobby deck or a strictly timed pecha-kucha. If you also want the room to see the time remaining, run the overlay on top — the auto-advance handles the slides while SlideTimerApp shows the visible countdown.

How to put a timer on one specific slide

PowerPoint has no native "show a countdown on this slide only" button, so you have two routes:

• Per-slide auto-advance: select just that slide, go to Transitions ▸ Advance Slide ▸ After, set the seconds, and do not click Apply To All. Only that slide advances on the timer. (This moves the slide; it doesn't display a visible number.)
• Visible countdown on that slide: either embed a timer GIF/MP4 sized to that slide (Method 2 above), or simply start the SlideTimerApp overlay when you reach the slide and reset it with R. The overlay is the only option that lets you start, pause and reset the visible count live for that one section.
