QR Code Generator

This QR code generator accepts a payload and encodes it into a scannable symbol that conforms to the QR standard. It supports common payload types such as URLs, plain text, email addresses, phone numbers, and SMS messages, making it suitable for developers embedding codes in apps, marketers tagging products, or educators distributing quick links. The tool validates inputs, configures output size, and applies a chosen error correction level to balance capacity and resilience. Conceptually, encoding involves selecting an appropriate version, determining the encoding mode (byte or alphanumeric), converting the payload to a bitstream, applying Reed-Solomon error correction, and rendering the final image. Output formats include PNG data URIs and SVG vectors, enabling high-quality prints or web use. Core features ensure deterministic results across sizes, with capacity checks to prevent unusable codes. The tool is designed for repeatable generation in automated workflows, content production, and educational demonstrations. Unique value lies in clear guidance on encoding rules, strict validation, and consistent rendering without brand-specific customization. Use cases span product packaging, event tickets, printed handouts, and digital documents that require reliable, machine-readable links.
