What is a URL QR Code?
A URL QR Code is a QR code that contains a web address. When scanned with a smartphone or QR code reader, it automatically opens the associated webpage in the user’s browser.
Can I add my logo to the QR code?
Yes. You can upload a logo that will be placed in the center of the QR code, helping reinforce your brand identity while maintaining scannability when used correctly.
Does adding a logo affect QR code readability?
Potentially, yes. Since the logo covers part of the QR code, very large logos may make scanning more difficult. Using an appropriate error correction level helps compensate for the covered area.
What is Error Correction?
Error correction is a built-in feature of QR codes that allows them to remain readable even if part of the code is damaged, obscured, or covered by a logo.
Which Error Correction level should I choose?
- L (7%): Best for simple QR codes without logos.
- M (15%): Suitable for small logos.
- Q (25%): Recommended for most branded QR codes.
- H (30%): Ideal for larger logos or advanced custom designs.
Can a QR code become unscannable?
Yes. Excessive customization, poor color contrast, oversized logos, or insufficient error correction settings can reduce readability and make a QR code difficult or impossible to scan.
What is the maximum recommended logo size?
As a general guideline, the logo should not exceed 20–25% of the total QR code area. Larger logos may require Error Correction Level H and thorough testing across different devices.
Do all smartphones support QR code scanning?
Most modern smartphones include built-in QR code scanning through the camera app. Older devices may require a dedicated QR code scanning application.
Can I change the URL after generating the QR code?
If the QR code contains a static URL, the destination cannot be changed after generation. To update destinations without creating a new QR code, you would need a dynamic QR code solution.
Why isn’t my QR code scanning correctly?
Common causes include:
- Low color contrast between the QR code and background.
- A logo that is too large.
- Insufficient error correction.
- Very small print sizes.
- Blurry or low-resolution images.
- Physical damage to printed QR codes.
What is the minimum recommended print size?
For most applications, a QR code should be printed at a minimum size of 2 × 2 cm (0.8 × 0.8 inches). Larger sizes may be required when the code is scanned from greater distances.
Should I test my QR code before publishing?
Yes. Always test your QR code on multiple devices and under real-world conditions before using it in marketing materials, packaging, signage, or printed documents.
