What it is

Favicon.one is a free web service that converts an uploaded image into a favicon package for modern websites. The upload form accepts PNG, JPG, SVG, GIF, WebP, BMP, and ICO files up to 10MB. Generated output includes ICO and PNG icons, an Apple touch icon, Android Chrome icons, and a web manifest. The site supplies HTML snippets and setup guidance for Next.js, plain HTML, Vue/Nuxt, Gatsby, and SvelteKit. Companion tools cover text-based favicons, emoji favicons, checking, and downloading; the emoji tool uses graphics from the open-source Twemoji project. No account or subscription is required.
