What it is

Favium generates favicon and app icon files from images, browser canvas content, or text. Its outputs include ICO files, PNGs, HTML snippets, and web manifests. ICO files can bundle 16, 32, 48, and 256 pixel entries, while PNG favicons can be exported at any resolution. In a browser, its canvas API creates favicons from an HTMLCanvasElement without a server. The CLI accepts local files, directories, WebP images, and remote URLs, and can create lettermark icons from text. Presets include default, web-app, apple-android, and custom options, with custom size bundles available. The web-app preset is described as ready for Android, iOS, and browsers; the generated assets are described as compatible with modern browsers, PWAs, and mobile devices. Favium is a free, open-source tool under the MIT license. The site shows installation with npm install favium and CLI use with npx favium-cli@latest, and welcomes contributions, issues, and feedback.
