QR Code Generation Libraries: Python, JavaScript, and More


A comprehensive comparison of QR code generation libraries across popular programming languages to help you choose the right tool for your project.


Python Libraries


segno: Standards-compliant, fast, pure-Python. Supports Micro QR, structured append, and multiple output formats (SVG, PNG, EPS, PDF). No pillow dependency for SVG output.


qrcode (python-qrcode): Feature-rich with pillow integration for image manipulation. Good for custom designs with logo overlay and colour customisation. Widely used with extensive documentation.

JavaScript Libraries


qrcode (qrcodejs): Simple browser-based generation. Renders to Canvas or img element. Minimal API surface.


qr-code-styling: Advanced styling with rounded modules, gradients, and logo embedding. Works in browser and Node.js.


qrcode-generator: Lightweight, no dependencies. Good for server-side Node.js generation.


Go Libraries


go-qrcode (skip2): Simple API, outputs PNG. Good for server-side generation in Go microservices.


go-qr (makiuchi-d): Lower-level control, supports custom rendering.


Rust Libraries


qrcode-rs: Pure Rust, fast generation. Outputs to various formats via image crate integration.


Java Libraries


ZXing: The reference implementation for 2D barcode generation and reading. Supports all QR code features including encoding modes and structured append.


Choosing a Library






Need
Recommended






Standards compliance
segno (Python), ZXing (Java)




Custom visual design
qr-code-styling (JS), qrcode (Python)




Server-side performance
go-qrcode (Go), qrcode-rs (Rust)




Browser generation
qr-code-styling (JS)




Micro QR support
segno (Python)






Key Takeaways


    

  • Python: segno for standards compliance, qrcode for design flexibility
    • 

  • JavaScript: qr-code-styling for advanced visual customisation
    • 

  • Go and Rust: high-performance server-side generation
    • 

  • ZXing (Java) is the reference implementation for the QR code specification
    • 

  • Choose based on your needs: compliance, design, performance, or platform
