What @profullstack/favicon-generator is
@profullstack/favicon-generator is a free command-line and programmatic package for generating PNG icon sets from SVG or PNG sources. It creates Apple Touch Icons from 57×57 through 180×180 and PWA icons from 192×192 through 512×512. Optional 16×16 and 32×32 favicon files can be produced or disabled. The CLI includes interactive operation plus controls for quality, compression, output directory, and silent mode. Developers can call the ESM functions `generateIcons` and `generateCustomIcons`, while configuration covers PNG quality, compression, favicon sizes, and custom sizes. Installation works with pnpm, npm, or yarn, including global CLI installation. Node.js 20 or later and ESM support are required. JPG input is not supported. Non-square or undersized PNG sources trigger warnings, then continue with upscaling and padding. The MIT-licensed repository directs questions and issues to GitHub.
