Favicon.one
What it is
Favicon.one is a free web tool that converts uploaded images into favicon packages for websites. It accepts PNG, JPG, SVG, GIF, WebP, BMP, and ICO files, with uploads limited to 10MB. A generated package includes ICO and PNG icons, an Apple touch icon, Android Chrome icons, and a web manifest. The site provides HTML snippets and framework guidance for Next.js, plain HTML, Vue/Nuxt, Gatsby, and SvelteKit. Linked companion tools handle text-to-favicon and emoji-to-favicon conversion, favicon checking, and favicon downloading; the emoji tool says its graphics come from the open-source Twemoji project. The service requires no registration and has no subscription. Its terms state that uploaded images are processed temporarily and automatically deleted from servers within 24 hours, while users retain ownership of uploads and generated favicons. Usage may be limited if servers are overloaded, and maintenance downtime may occur. The site invites questions to support and credits Assistsoft as the maker.
