A QR code on a slide is one of the easiest ways to hand your audience something mid-talk: your slides, a feedback form, a sign-up page, a resource list or your contact card. Nobody has to copy down a long web address. PowerPoint doesn't have a built-in "QR code" button, but you don't need one. Make the code as an image, then insert it like any picture. The part that takes a bit of thought is size: a code that looks fine on your laptop can be hard to scan from the back of a room.
The short answer
- Create the QR code for your link and download it as a PNG at a large pixel size.
- Insert it: Insert → Pictures → This Device (on a Mac, Insert → Pictures → Picture from File).
- Make it big. For a projected slide, a code that fills roughly a third to half of the slide height is a sensible starting point.
- Keep a white margin (quiet zone) around it and good contrast with the background.
- Add a hyperlink to the image so people reading the deck or a PDF can click instead of scanning.
- Test it from the back of the room, or on a shared screen, before you present.
Step 1: make the QR code
Use our free generator to create a code for a website address, text, WiFi details or a contact card. A few tips for slides:
- Use a short link where you can. Shorter content means fewer, larger squares in the code, which are easier to scan from a distance. Our explainer on how much data a QR code can hold shows why.
- Choose a large size. Set the size near the top of the range (for example 1,024 px) before downloading. A big image can be scaled down cleanly; a small one stretched up can look soft.
- Stick with dark on light. Black on white is the safest. If you want brand colors, read QR code colors that scan first.
- Static codes don't expire. A code made in our generator points straight to your link. If you think the destination might change, read static vs dynamic QR codes.
Step 2: insert it into PowerPoint
PowerPoint for Windows
- Go to the slide where you want the code.
- Choose Insert → Pictures → This Device.
- Select your downloaded PNG and click Insert.
PowerPoint for Mac
- Choose Insert → Pictures → Picture from File.
- Select the PNG and click Insert.
PowerPoint for the web
- Choose Insert → Pictures → This Device.
- Upload the PNG.
You can also drag the file from your desktop or downloads folder straight onto the slide in most versions. Menu names can differ slightly between versions.
What about add-ins?
The Office add-in store (Insert → Get Add-ins, or Home → Add-ins in some versions) lists third-party QR code add-ins that generate a code inside PowerPoint. They can be handy, but they vary in quality and may require an account. Making the code yourself and inserting a picture works in every version and keeps you in control of the file.
Step 3: size and place it for the room
The common rule of thumb for QR codes is that the code should be about one tenth of the scanning distance wide. Our QR code size for print guide explains it. On a slide, what matters is how big the code ends up on the projected screen.
Worked example. A standard widescreen (16:9) slide is 13.333 inches wide by 7.5 inches tall. Say you make the QR code 3 inches wide on the slide.
- Share of the slide width: 3 ÷ 13.333 ≈ 0.225 (22.5%)
- If the projected image is 3 meters wide: 3 × 0.225 = 0.675 m, about 68 cm across
- Using the 10:1 rule: 0.675 × 10 ≈ 6.75 m comfortable scanning distance
If the projected image were only 1.5 meters wide, the same code would be about 34 cm across, good for roughly 3.4 meters. In a big room or a long hall, make the code larger, or repeat it on a closing slide.
Placement tips:
- Give it its own space. Don't overlap text, photos or background patterns.
- Avoid the very bottom edge if heads in front might block it.
- Keep the slide up long enough. Say "scan this now" and pause; people need a few seconds to open their camera.
- Add a short label under the code, such as "Scan for the slides," plus a short typed link for anyone who can't scan.
Step 4: keep it sharp
- Resize from a corner handle, not a side handle, so the code stays square. In Format Picture → Size, make sure Lock aspect ratio is ticked.
- Turn off image compression. In desktop PowerPoint for Windows, go to File → Options → Advanced and, under Image Size and Quality, tick Do not compress images in file. On a Mac and in the web version, options differ.
- Don't apply artistic effects, shadows or 3D rotation to the code. A small picture border is fine if the white margin stays.
- Mind your slide background. On a dark theme, leave the code on a white square with a generous margin. See our guide to the QR code quiet zone.
Step 5: make it clickable too
Many people will see your deck later, as a shared file or PDF, on the same device they would scan with. A clickable code helps them:
- Select the QR image.
- Choose Insert → Link (or press Ctrl+K, Cmd+K on a Mac).
- Paste the same address the code points to.
The link works in slideshow mode and usually carries over when you export to PDF, so readers can tap instead of scanning their own screen.
Step 6: test before you present
- Scan it on your laptop screen with two different phones, an iPhone and an Android if you can.
- Scan it from the projector, from the back row and from an angle, during your tech check.
- For video calls, share your screen with a colleague and ask them to scan from their monitor. Screen-sharing can reduce quality, so make the code larger and keep the slide up longer.
- For printed handouts, remember that printing several slides per page shrinks the code. Print a test page and scan it.
If it won't scan, our QR code not scanning checklist covers the usual causes: too small, too little contrast, a missing margin or too much data.
Good uses for a QR code on a slide
- Download the slides or a resource list at the end of a talk.
- Feedback or questions with a Google Form QR code.
- Contact details using a vCard QR code.
- Event registration or a sign-up page.
- A live poll or a quiz link in a classroom.
Frequently asked questions
Does PowerPoint have a built-in QR code generator?
Not as a standard ribbon button. The simplest approach is to create the code as an image and insert it; third-party add-ins are also available.
How big should a QR code be in PowerPoint?
For projection, a code that takes up roughly a third to half of the slide height is a good start. Use the 10:1 distance rule with the projected size to check it for your room.
Why is my QR code blurry in PowerPoint?
Usually because a small image was stretched or the file was compressed. Insert a larger PNG, resize from a corner, and turn off image compression.
Can people click a QR code in a PowerPoint PDF?
Yes, if you add a hyperlink to the image before exporting. The link usually carries over to the PDF.
