QR Code Generator

This tool encodes input data into a QR Code image suitable for scanning by standard readers. It accepts plain text, URLs, and vCard payloads, and outputs either a PNG raster image or an SVG vector, allowing easy integration into documents or web pages. Conceptually, the encoder follows official QR specifications, mapping data to a modular grid, selecting a compatible version and error correction level, and rendering modules as dark and light squares within a centered area. The result is a compact, machine readable representation that remains legible across devices. Beneficiaries include developers embedding QR creation in apps, marketers generating campaign codes, educators sharing links, and event organizers distributing attendee data. The tool differentiates itself by offering explicit control over version selection, error correction, and margins, plus no expiration on generated codes, enabling reproducible results and long term use. Core features include input validation, automatic version estimation, configurable ECC, border margins, multi format output, and deterministic rendering for consistent results across runs. Typical use cases include encoding a product URL for packaging, a vCard for contact sharing, or a plain text note for quick reference. The tool supports safe defaults and advanced options for precise requirements, ensuring scannability while enabling customization for different media.
