How to Add a QR Code to a Presentation
The end of a talk is the moment people act. A large, well-placed QR code turns that moment into downloads, bookings, and survey responses. You can do all of this free at liveqr.codes — no signup needed for a static code, and a one-time $1.99 upgrade unlocks unlimited dynamic codes with scan analytics.
Steps
- Pick one destination — One code, one action: the slide deck, a booking calendar, or a feedback form. Multiple codes on a slide split attention and reduce scans.
- Generate a high-resolution code — Download the SVG or a PNG at least 1000px wide so it stays crisp when projected.
- Insert and size it on the slide — Place it in a corner or centre of the closing slide at roughly 20% of slide height. Keep a white box behind it if the theme is dark.
- Leave it on screen long enough — Hold the slide for at least 20 seconds and say out loud what scanning does.
- Test from the back of the room — Project the slide and scan from the furthest seat. If it fails, enlarge the code rather than moving people closer.
Pro tips
- Never place a QR code over a photo or gradient background
- Repeat the code on the opening slide for latecomers
- Use a dynamic code so one deck can serve different events
Frequently asked questions
What size should a QR code be on a slide?
About one fifth of slide height. Projected codes need to be far larger than screen codes.
Can people scan a QR code from a screen?
Yes, as long as contrast is strong and the display is not overly glossy or dimmed.
Should I use one code or several?
One. A single clear action converts far better than a slide full of competing codes.
