What is QR Code Generator?
A QR code is a two-dimensional matrix code that directly stores a URL, text or structured payload for compatible phones and scanners.
Main use case: Create and download a static QR code with controlled content, colors, quiet zone, size and error correction.
Common use cases
- Links and documents
- Share an HTTPS page, form, menu or documentation.
- Wi-Fi access
- Encode SSID, security and password in a structured Wi-Fi payload.
- Contact card
- Share a vCard 3.0 with name, phone, email, organization and website.
- Mobile action
- Prepare an email, phone call or SMS after scanning.
Common mistakes
- Unnecessarily long content
- More bytes increase the QR version, module count and required physical size.
- Removed quiet zone
- Tight cropping removes the clear area scanners use to isolate the symbol.
- Low contrast
- A dark background or pale foreground reduces scan reliability.
- Untested final asset
- Test the QR code at its real display or print size.
