A QR (Quick Response) code is a two-dimensional barcode that can store text, URLs, contact information, and other data. QR codes can be scanned with smartphone cameras or QR reader apps to instantly access the encoded information without typing. Encode UUIDs for asset tracking.

What can I encode in a QR code?

You can encode plain text, URLs/website links, email addresses, phone numbers, WiFi credentials, contact information (vCards), SMS messages, geographic coordinates, and more. The data limit is approximately 4,296 alphanumeric characters, though smaller codes scan more reliably. Validate your URLs before encoding.

Can I customize the QR code appearance?

Yes, you can customize the size, foreground (dark) and background (light) colors of your QR code. However, ensure sufficient contrast between colors for reliable scanning. Black on white provides the best scanning reliability. Use our Color Converter to pick colors.

Are the QR codes created here free to use?

Yes, absolutely! All QR codes generated are free to use for any purpose - personal or commercial. The codes are created locally in your browser and are not tracked, stored, or watermarked. You own the generated QR codes completely.
