QR Maker

The QR Maker encodes data into a QR matrix using standard QR code logic and exposes a simple set of inputs for data and presentation. It supports common payloads such as URLs, plain text, contact data, and small payloads that fit within a chosen version and error correction level. Conceptually, data is converted into a grid of modules that can be rendered as SVG or raster PNG, ensuring compatibility across platforms. The tool targets developers integrating QR generation into apps, marketers creating campaign assets, and teams delivering scannable materials in print or online. Unique value lies in its combination of precise encoding controls (version, ECC, margin) with straightforward outputs that fit into automation workflows. Core features include: adjustable size, selectable ECC level, optional logo embedding, and two output formats (SVG and PNG). Use cases include embedding a product page URL on packaging, placing a QR code on an event ticket, or generating a batch of codes for a marketing campaign. This tool avoids UI discussions and focuses on domain logic, correctness, and integration pathways. The approach balances accuracy with simplicity, enabling quick generation while preserving scan reliability across devices.
