QRCoder is a pure C# library for generating QR codes and Micro QR codes with zero external dependencies. It supports multiple output formats (PNG, SVG, PDF, ASCII, Bitmap, PostScript) and includes 23+ payload generators for structured data like WiFi credentials, vCards, and payments.
Use cases
- generate qr code images in c#
- create wifi qr codes from .net
- generate svg qr codes
- encode vcard contact info as qr code
- generate girocode or swiss qrcode payment codes
- create micro qr codes for small labels
- render qr codes as png bitmaps in .net
When to choose
- you need QR code generation in any .NET application without external dependencies
- you need multiple output formats like PNG, SVG, or PDF
- you need structured payload generators (WiFi, vCard, payments)
- you need cross-platform support across .NET Framework, .NET Core, and .NET 5+
When to avoid
- you need to decode or read QR codes rather than generate them
- you need barcode formats other than QR and Micro QR codes
- you are not working in a .NET/C# environment
