How to Add a Logo to a QR Code for Free

A plain black-and-white QR code works just fine, but it looks like something from a shipping label. Adding your logo in the center makes it seem intentional — a brand asset rather than a utilitarian sticker. The great part is that including a logo doesn't need any fancy paid tools or professional design skills. Plus, as long as you do it right, the QR code will still scan just fine.

Why Adding a Logo Is Safe — Error Correction Explained

QR codes handle wear and tear pretty well. They've got four error correction levels — L, M, Q, and H — that allow parts of the code to be messed up or damaged. Yet, they still scan just fine because of this.

Error correction level H — what it means and why it matters when using a logo

Level H (High) allows up to 30% of the QR code's data modules to be obscured and it will still decode. When you place a logo in the center, you're intentionally covering part of the pattern — and error correction is what compensates for it. For a deeper explanation of how QR error correction works, see our how-it-works page.

Uploading a logo on genqrfree.com sets the generator to error correction level H automatically. No setup required! But level H creates a denser QR code, meaning more modules fit into each inch. That's why logos need a bigger print size compared to simpler QR codes—especially for tiny prints.

Step-by-Step: Add a Logo to Your QR Code

Step 1: Generate your QR code Go to genqrfree.com, select your QR type (URL, WiFi, vCard, etc.), and enter your data. The QR preview appears on the right.

Step 2: Open the Logo panel In the customization panel, click Logo. A logo upload area appears.

Step 3: Upload your logo Click Upload Logo and select your file. PNG with a transparent background gives the cleanest result. JPG works but will show a white square behind the logo. The logo is placed automatically in the center of the QR.

Step 4: Adjust the logo size Slide the size control to adjust how much of the QR code your logo covers. Stay below 25% of the QR width; the generator will warn you if it's too big.

Step 5: Check the preview and download The live preview updates immediately. Scan the preview on screen before downloading — if it scans correctly on screen, it will scan correctly in print. Click Download PNG or Download SVG.

Logo Preparation Tips

The quality of your logo file directly affects how the final QR looks. A few minutes spent here saves a lot of back-and-forth:

• Use PNG with a transparent background — this lets the logo sit cleanly inside the QR without a white box behind it
• Keep the logo under 20–25% of the QR code's total width — beyond that, error correction can't compensate and scannability drops
• Square or circle logos work best — wide rectangular logos need to be shrunk so much they become unreadable at print sizes
• High contrast with the QR foreground color — if your QR is dark indigo and your logo is dark navy, it'll disappear; use a logo version that stands out
• Test scan after uploading — scan the live preview from your phone before downloading; this takes 10 seconds and confirms everything is working

For use in printed materials, also check the print QR code guide for size and resolution requirements. When you're ready to print the branded QR on posters or flyers, that guide covers file formats, quiet zones, and placement rules.

How Much of the QR Can the Logo Cover?

The safe ceiling is 25% of the total QR area — meaning the logo's width should be no more than about 1/4 of the QR's full width.

Why 25%, not 30%? Error correction level H lets for 30%, but that's for random, spread-out damage, not a solid opaque block right in the center. The logo takes up contiguous modules there, making it tougher for decoders to fix. So, sticking with 20-25% actually provides the real-world safety buffer we need.

Practical size rule:

• QR at 500px → logo max ~125px wide
• QR at 1000px → logo max ~250px wide
• QR at 2000px → logo max ~500px wide

If your logo is wider than tall, like a horizontal wordmark, you'll either have to make it super small or crop it to show only the icon. The icon alone, minus the text, works better for QR codes.

Color Combinations That Work

The logo doesn't need to match the QR color. In fact, contrast between the logo and the QR pattern makes both more readable:

What doesn't work: a dark logo on a dark QR, or a light logo on a light QR. The logo needs to be visually distinct from the QR modules around it, not camouflaged.

For vCard QR codes on business cards, the logo in the center is particularly effective — it reinforces the brand at exactly the moment someone is saving your contact details. See the full guide on business card QR code with your logo for card-specific sizing and placement tips.

Frequently Asked Questions

Will adding a logo make the QR code harder to scan? You're good to go as long as your logo stays under 25% of the QR code's width and the generator uses error correction level H. In reality, a properly sized logo doesn't affect scan speed or reliability. Problems only show up when logos are too big, contrast is too low, or the QR code is printed too small. Just make sure to test-scan the preview before downloading.

What file formats work for the logo upload? PNGs are better than JPGs for QR codes because they support transparency. That way, your logo sits right on top of the code without a white box. With JPGs, the logo's background stays as a white square that shows up on non-white QR codes. So, if you can't use a PNG, go to a site like remove.bg or Canva to take the background off before making the QR code.

Can I use any size logo? The file can be any size; the generator will adjust it to fit. The key detail is the logo's proportion—it shouldn't cover more than 20-25% of the QR code's total width in the end. Wide logos, like horizontal wordmarks, usually look better using just the icon or mark. This part then scales more proportionally into the QR center.
