Favium review
A flexible open-source option for favicon bundles, manifests, and app icons.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Favium is an open-source favicon generator for developers working in browser and command-line environments. It creates favicon bundles from canvas, image, or text sources, with outputs that include multi-size ICO files, custom-size PNG icons, HTML link snippets, and web manifest metadata. The project is available through an npm package, a browser-oriented API, and the Favium CLI, making it suited to developers who want repeatable icon generation in web projects or scripts.
Its strongest differentiator is the breadth of its output workflow. The Canvas-first browser API supports in-browser generation, while the CLI can work from local files, directories, or remote URLs. Text-based lettermarks provide an option when a source image is not available. Presets cover web, PWA, Apple, and Android icon bundles, while custom sizes allow a more tailored output. This combination gives Favium a practical role in projects that need more than a single favicon file, particularly when HTML and manifest metadata should be generated alongside the icons.
Favium keeps its scope focused on technical asset generation rather than visual design or broader image editing. Teams seeking a graphical, design-led workflow may prefer a tool built around visual editing, while developers who want scriptable generation can make better use of the CLI, API, and npm package. The open-source model and free availability also fit projects that want a locally controlled utility without a paid-tier structure. Pick Favium for browser and automation workflows involving favicons, manifests, and platform icon sets; look elsewhere if the priority is collaborative design work or a general-purpose image editor.
