QR Code Generator

QR codes (Quick Response codes) are two-dimensional barcodes that can store text, URLs, contact information, Wi-Fi credentials, and more. They are scanned instantly by any smartphone camera, making them one of the fastest ways to share information in the physical world. Common uses include linking to websites from printed materials, sharing Wi-Fi passwords with guests without typing, adding contact details to business cards, and enabling mobile payments. QR codes can hold up to about 4,000 characters of text, which is enough for most practical applications.

Select a preset to match your use case. The URL/Text preset works for any plain text or web address. The Wi-Fi preset generates a special format that lets phones connect to your network automatically when scanned. The vCard preset creates a digital contact card, and the Email preset generates a mailto link. Customize the foreground and background colors to match your branding, and choose a size appropriate for your medium. Download the result as PNG for digital use or SVG for print materials that need to scale to any size.

Always maintain high contrast between the foreground and background colors. Dark modules on a light background work best for scanner compatibility. Test your QR code with multiple devices before printing to ensure it scans reliably. For print materials, use SVG format so the code stays sharp at any size. Keep the encoded data as short as possible because more data means a denser code that is harder to scan from a distance. If linking to a URL, consider using a short link service to minimize the data payload.
