Frequently Asked Questions
What is a QR Code with text/label?
A QR code with text adds a human-readable label or caption directly below the QR image. This helps viewers understand what the code links to before scanning—useful for branding, instructions, or accessibility.
Why add a caption below a QR code?
Captions build trust and increase scan rates. A label like "Scan for WiFi Password" or "Visit Our Menu" tells users exactly what to expect, reducing hesitation and improving engagement.
Does the label affect QR code scanning?
No. The label sits outside the QR code's quiet zone (margin), so it does not interfere with scanning. As long as the QR code itself has sufficient contrast and margin, scanners will read it perfectly.
Can I use custom colors safely?
Yes—provided the contrast ratio between foreground and background is high enough. Dark-on-light combinations work best. Always test your QR code with multiple scanner apps after customizing colors.
What file format do I get when downloading?
You get a high-resolution PNG image that includes both the QR code and your custom label merged into a single file—ready for print, web, or sharing.
How much text can a QR code hold?
A QR code can store up to 4,296 alphanumeric characters or 2,953 bytes of binary data. For URLs and short messages, this is more than sufficient. Longer content will require higher error-correction levels or larger QR sizes.
What are good practices for QR code labels?
Keep labels short and actionable (under 60 characters). Use clear fonts, ensure sufficient spacing from the QR code, and choose colors that complement your brand while maintaining readability.
Can I use this tool for commercial projects?
Absolutely. The QR codes you generate are yours to use freely—in print materials, product packaging, business cards, flyers, menus, signage, and digital media. No attribution required.
