QR Code Generator

QR codes can store a wide variety of data types including URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi network credentials (SSID and password), contact information in vCard format, calendar events, geographic coordinates, and Bitcoin payment addresses. The maximum storage capacity depends on the QR code version and error correction level, ranging from a few dozen characters for numeric-only data to several thousand characters for binary data. For most practical use cases like URLs and contact info, standard QR codes provide more than enough capacity.

Yes, all QR codes generated by this tool are completely free to use with no expiration date, no usage limits, and no watermarks. You can download them as many times as you want and use them for any purpose — personal, commercial, educational, or otherwise. There are no hidden fees, subscription requirements, or premium tiers. The QR codes are yours to use however you see fit, whether for business cards, marketing materials, product labels, or personal projects.

You can download your generated QR code in two formats: PNG (Portable Network Graphics) and SVG (Scalable Vector Graphics). PNG is a raster format ideal for digital use on websites, social media, email signatures, and presentations. SVG is a vector format that can be scaled to any size without losing quality, making it perfect for print production on business cards, posters, banners, and product packaging. Both formats are widely supported by design software and can be easily incorporated into your existing workflows.

Yes, you can customize both the foreground (dark modules) and background colors of your QR code to match your brand identity or design aesthetic. However, it is important to maintain sufficient contrast between the foreground and background colors to ensure reliable scanning. High contrast combinations like black on white work best. Avoid using light colors for the foreground or dark colors for the background, as this can make the QR code difficult or impossible for scanners to read. Always test your customized QR code with multiple scanner apps before printing or distributing it widely.

QR codes have a maximum data capacity that depends on the version (size) and error correction level. A standard QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters at the highest version with the lowest error correction. However, larger data payloads result in denser QR codes with smaller individual modules, which can be harder to scan reliably, especially from a distance or with lower-quality cameras. For best results, keep URLs under 200 characters and use URL shorteners for very long links. This ensures your QR code remains clean, scannable, and visually appealing.
