Frequently Asked Questions
What can I encode in a QR code?
Any text up to about 3,000 characters can be encoded in a QR code. Common uses include URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages (smsto:), Wi-Fi credentials (WIFI:), vCard contacts, and calendar events.
What is error correction level?
Error correction allows a QR code to be read even when it's partially damaged or obscured. Level L (7%) is smallest but least robust. Level M (15%) is the standard choice. Level Q (25%) suits codes that might be partially covered. Level H (30%) is best for printed codes that may get dirty or damaged.
What size should I use?
256px is fine for digital use (websites, emails, presentations). Use 512px or 1024px for print to ensure the QR code remains sharp at the final printed size.
Can I use custom colors?
Yes. Use the foreground and background color pickers to choose any colors. Ensure sufficient contrast between the two colors — dark foreground on light background is easiest for scanners to read. Avoid low-contrast or inverted color schemes.
About QR Code Generator
The QR Code Generator creates scannable QR codes from any text or URL, directly in your browser. QR codes have become indispensable in marketing, hospitality, retail, and everyday digital communication — from restaurant menus and product packaging to business cards and event tickets. This tool lets you create professional-quality QR codes in seconds, with full control over size, error tolerance, and colors.
The generator uses the qrcode library to produce pixel-perfect QR codes using the ISO 18004 standard, ensuring compatibility with all modern smartphone QR readers including the built-in camera apps on iOS and Android. The QR code preview updates in real time as you type, giving you instant visual feedback before downloading.
Error correction is one of the most important settings for physical QR codes. When a QR code is printed on packaging, displayed outdoors, or embossed on a surface, it may be partially obscured or damaged. Higher error correction levels allow the code to be successfully scanned even when up to 30% of its surface is unreadable. For digital-only uses (screens), Level L or M provides the smallest, fastest-scanning code.
Custom colors open creative possibilities for branded QR codes. Adding your brand colors to a QR code reinforces visual identity and makes it look intentional rather than generic. The key rule is maintaining high contrast — the scanner needs to clearly distinguish the dark modules from the light background. Test your colored QR code with multiple devices before mass printing.
