What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores data in a grid of black and white squares. Originally designed for tracking automotive parts in manufacturing, QR codes are now used everywhere: restaurant menus, event tickets, business cards, payment systems, WiFi login, and marketing campaigns. They can encode URLs, plain text, email addresses, phone numbers, WiFi credentials, and more. Any smartphone camera can scan a QR code instantly.
Error correction levels
QR codes include built-in error correction using Reed-Solomon coding, allowing them to be read even when partially damaged or obscured. There are four levels: L (7% recovery), M (15%), Q (25%), and H (30%). Higher error correction means more data redundancy (and a denser code), but better reliability when the code is printed on curved surfaces, partially covered, or displayed at small sizes. For most use cases, level M provides a good balance between density and reliability.
Customizing QR codes for branding
While traditional QR codes are black and white, you can customize foreground and background colors to match your brand identity. The key constraint is maintaining sufficient contrast between the foreground modules and background for reliable scanning. Dark foreground on light background works best. This generator lets you choose from preset color schemes or define custom colors, and download the result as a high-resolution PNG or scalable SVG for print materials.
Frequently Asked Questions
What can I encode in a QR code?
You can encode URLs, plain text, email addresses (mailto:), phone numbers (tel:), WiFi credentials (WIFI:T:WPA;S:NetworkName;P:Password;;), vCards, and more. The maximum capacity depends on the error correction level and data type.
Which download format should I use?
Use PNG for digital displays, social media, and quick sharing. Use SVG for print materials, as SVG scales to any size without losing quality. SVG files are also smaller and can be further customized in design tools.
Can I use custom colors?
Yes. Choose from preset color schemes or pick custom foreground and background colors. Ensure there is enough contrast between the two colors for reliable scanning. Dark foreground on light background is recommended.
