- What can I encode in a QR code?
- URLs, plain text, WiFi credentials (SSID and password), phone numbers, email addresses, vCards, and any other text-based data can be encoded into a QR code.
- What size QR code should I use?
- For digital screens, 400px is fine. For print use, generate at least 600px to ensure it scans reliably at small printed sizes. Larger QR codes with less data are easier to scan.
- Are the QR codes free to use commercially?
- Yes. All QR codes are generated in your browser using open-source libraries and are completely free to use for any purpose, including commercial use.
