A QR code with a centered logo is the difference between "generic internet clipart" and "a deliberate part of your brand." It's one of the easiest upgrades you can make to a printed material — and if you do it right, it doesn't cost you any scannability at all.
This guide walks through how to add a logo to a QR code on QuicklyGenerateQR, explains the science behind why it still works, and covers the handful of mistakes that actually break scanning.
Why a QR code survives a logo on top
The idea that covering part of a QR code with a logo should break it is intuitive but wrong. QR codes have a built-in feature called error correction — redundant data baked into the pattern that lets a scanner reconstruct the full message even if part of the code is damaged, smudged, or obstructed.
The ISO/IEC 18004 standard defines four error correction levels:
| Level | Recovery capacity | Typical use |
|---|---|---|
| L | ~7% | Clean print, no obstruction |
| M | ~15% | General use, default for most codes |
| Q | ~25% | Industrial environments |
| H | ~30% | Logo embedded or damaged surfaces |
A level-H code can lose up to 30% of its surface and still decode. A centered logo that occupies 15-20% of the code's total area sits comfortably inside that margin, with safety to spare.
QuicklyGenerateQR handles this automatically. The moment you drop a logo into the generator, the error correction level is bumped to H. You don't need to touch a setting.
The six-step workflow
Open the generator
Head to the free QR code generator and pick whatever QR type you need — URL, vCard, WiFi, or any of the other static types. The logo workflow is identical for all of them.
Keep your payload short
If you're encoding a long URL, consider shortening it. Shorter content produces a simpler pattern, which gives the logo more room to breathe inside the error correction margin. For data over 200 characters, consider a dynamic QR code that encodes a short redirect URL instead.
Upload your logo
SVG is the best format (scales without pixelation). PNG is good for logos with transparency. JPG works but doesn't support transparent backgrounds, so the logo's background color will show.
Position and size it
The generator places the logo in the center by default — the only safe position. Keep the logo under 25% of the code's total area (roughly 20% of width × 20% of height). Bigger than that and you exceed the error correction margin. The default size enforced by the generator is the sweet spot.
Verify color contrast
The logo doesn't need to match the QR code colors, but the code itself still needs high contrast between foreground and background. Dark QR on white background is the safest baseline. See the color customization guide.
Download and test
Export as SVG. Scale to the target size, and scan with two different phones from a realistic distance. This step is non-negotiable — real-world conditions surface edge cases a perfect preview can't show.

Rules for logo files that scan reliably
Use a simple, recognizable shape
Complex logos with fine detail disappear at small code sizes. An icon or monogram works better than a full wordmark. If your logo has text, make sure the letters are bold enough to read at 4 mm tall.
Avoid heavy outlines
Thin outlines blur into the QR modules around them and hurt scanner edge detection. If your logo has an outline, give it either a clean solid border or no border at all — don't leave thin wisps.
Use high contrast inside the logo
A logo with its own dark-on-light or light-on-dark contrast reads more clearly than a logo that matches the QR code colors. A distinct visual boundary between the logo and the QR pattern helps.
Give it a clear edge
Transparent backgrounds are fine; solid backgrounds are fine. What you want to avoid is a logo that bleeds into the QR pattern. A thin white halo around the logo, even just 2-3 pixels, dramatically improves edge detection.
Common mistakes
- Logo too large. Anything over 25% of the code's area pushes past the error correction margin and makes the code unreliable. Resist the urge to make it bigger just because the preview looks nicer.
- Low-contrast logo edges. If the logo's outline blends into the modules around it, the scanner's edge detection fails. Distinct borders are mandatory.
- Not bumping error correction. If you're using a generator that doesn't auto-adjust the error correction level, you're relying on the default Level M, which only tolerates 15% obstruction. QuicklyGenerateQR handles this automatically — but if you're using a different tool, check the setting manually.
- Testing only on a brand-new iPhone. Older phones (3+ years old) have less forgiving cameras. Test on whatever "worst case" device your audience is likely to use.
- Animating the logo in digital contexts. An animated logo inside a QR code is fun in theory and catastrophic in practice — scanners can't lock focus on a moving target.
Error correction is the invisible feature that makes branded QR codes possible. Understand it once, and you'll never print a code that "looks great but doesn't scan" again.
