QR code encoder

This tool encodes a payload into a QR code representation delivered as an SVG. It accepts text, URLs, vCard data, or other short payloads and outputs a scalable vector that can be embedded in print collateral, product packaging, posters, or websites. The output is resolution independent and ideal for high-DPI displays.\n\nEncoding follows the QR Code standard ISO/IEC 18004. The process checks payload length, selects the minimum version compatible with the chosen error correction level, encodes data with Reed-Solomon error correction, applies a masking pattern, and renders a 512x512 module matrix as crisp vector shapes.\n\nThe vector output ensures clean rendering across devices and can be styled via CSS without altering the encoded data. Optional inputs like size_px, margin_modules, and error_correction let designers adapt the code for small labels or large banners while preserving scan reliability.\n\nUse cases include product labels, tickets, event promotions, and digital content gating. The tool emphasizes standards conformance, determinism, and ease of automation: provide payload, adjust options, generate the SVG, and reuse across channels without introducing branding or vendor-specific formats.
