How does logo embedding work in QR codes?

QR codes include built-in error correction that allows them to be read even when partially damaged. When you add a logo, the tool increases error correction to Level H (30% recovery), meaning up to 30% of the QR code can be obscured and it will still scan correctly. The logo is placed in the center with white padding to ensure maximum readability.

What logo formats are supported?

PNG, JPG, and SVG files up to 2MB. For best results, use a simple logo with high contrast on a transparent or white background. Square or circular logos work best.

How large can the logo be?

We recommend keeping the logo between 15-25% of the QR code's area (adjustable with the size slider). Larger logos obscure more of the code, increasing the risk of scanning failure. The tool defaults to 20%, which is the optimal balance of visibility and reliability.

Will the QR code still scan with a logo?

Yes, as long as the logo is within the recommended size range. The tool automatically uses Level H error correction (30% data recovery) when a logo is present, ensuring reliable scanning even with the logo covering part of the code.

Why do other sites charge for this?

Logo embedding requires higher error correction and careful positioning. Many QR code generators offer this as a premium feature ($7-12/month). Our tool does all processing client-side with no server costs, so we can offer it free.

How Logo Embedding Works

QR codes have a remarkable feature: error correction. At the highest level (Level H), a QR code can recover up to 30% of its data even when that portion is damaged, dirty, or — in this case — covered by a logo.

When you add a logo, the tool automatically switches to Level H error correction and places the logo in the center of the code with white padding. The center is the optimal position because QR code readers start scanning from the three corner finder patterns (the large squares), so the center is the last area needed.

Logo Design Best Practices

Keep it simple. Detailed logos with fine text may be hard to see at small sizes. Icons and simple wordmarks work best.

Use high contrast. Your logo should stand out clearly against the white padding area. Dark logos on white work best.

Go square or circular. Square and circular logos fit naturally in the QR code's center. Wide rectangular logos may need to be cropped.

Stay under 25%. Keep logo size between 15-25% of the QR code area for reliable scanning.

Pro Tips

Always test your QR code before printing.

Scan it with at least 2 different phones (iPhone + Android) before sending anything to print. Different cameras handle low contrast and small sizes differently. A 30-second test can save a $500 print run.

Use error correction level H for challenging environments.

Level H can recover up to 30% of damaged data. This is required when adding a logo and recommended for curved surfaces, low-light environments, or partially obscured codes. For simple URLs on flat surfaces, Level M is fine.

For print, export SVG or use at least 1024px PNG.

SVG is infinitely scalable — perfect for business cards, posters, or packaging of any size. If you must use PNG, use 1024px+ resolution to avoid pixelation when printed large.

Keep your QR code content short.

Shorter URLs produce simpler QR codes with larger modules that are easier to scan. Use a URL shortener for long links. A 20-character URL produces a much more scannable code than a 200-character one.

WiFi QR codes are the most underused feature.

Print your WiFi QR code and tape it to your router, frame it in your guest room, or add it to restaurant table tents. Guests scan once and they’re connected — no more spelling out passwords.

Frequently Asked Questions

Is this QR code generator really free?+

Yes, completely free with no signup, no watermarks, no download limits, and no expiration on generated codes. All features including logo embedding, color customization, SVG export, and batch generation are available at no cost. All processing happens in your browser — we don’t store any of your data.

Do QR codes generated here expire?+

No. QR codes generated with this tool are static codes — the data is encoded directly in the image. They will work forever and don’t depend on any external service. As long as the destination URL is active, the QR code will work.

What is the best format to download my QR code?+

For most uses, PNG is the best choice. For print materials like business cards, posters, or packaging, SVG is ideal because it’s a vector format that scales to any size without losing quality. JPEG is smaller in file size but doesn’t support transparency.

Can I add my company logo to the QR code?+

Yes, you can upload any PNG, JPG, or SVG logo and it will be placed in the center of the QR code. The tool automatically increases the error correction level to H (30%) when a logo is added, ensuring the code remains scannable even with the logo covering part of it. We recommend keeping the logo under 25% of the QR code’s area.

How do I create a WiFi QR code?+

Click the WiFi tab, enter your network name (SSID), password, and select your encryption type (WPA/WPA2 is the most common). The tool generates a QR code that, when scanned by a smartphone, will prompt the user to connect to your WiFi network automatically. This works on iPhone (iOS 11+) and Android (10+).

What is error correction and which level should I use?+

Error correction allows QR codes to be read even when partially damaged or obscured. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Use Level M for most purposes. Use Level H when adding a logo, printing on curved surfaces, or in environments where the code might get dirty or damaged.

How small can I print a QR code?+

The minimum recommended print size is 2cm × 2cm (about 0.8 × 0.8 inches) for a QR code encoding a short URL. More complex codes with more data need to be larger. Always test by scanning from the intended viewing distance before mass printing.

Is my data safe? Do you store anything?+

All QR code generation happens entirely in your browser using JavaScript. No data is sent to any server. We don’t store, log, or transmit any content you enter — including URLs, WiFi passwords, contact information, or uploaded logos. Close the tab and everything is gone.

What’s the maximum amount of data a QR code can hold?+

A single QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters. However, more data means a more complex (denser) QR code that’s harder to scan. For best results, keep content under 300 characters. For URLs, use a URL shortener if the link is very long.
