 * Available in 6 programming languages, all with nearly equal functionality: Java, TypeScript/JavaScript, Python, Rust, C++, C
 * Significantly shorter code but more documentation comments compared to competing libraries
 * Supports encoding all 40 versions (sizes) and all 4 error correction levels, as per the QR Code Model 2 standard
-* Output formats: Raw modules/pixels of the QR symbol (all languages), SVG XML string (all languages except C), `BufferedImage` raster bitmap (Java only), HTML5 canvas (TypeScript/JavaScript only)
+* Output format: Raw modules/pixels of the QR symbol
 * Detects finder-like penalty patterns more accurately than other implementations
 * Encodes numeric and special-alphanumeric text in less space than general text
 * Open source code under the permissive MIT License
