About Favicon.one
We build fast, privacy-focused tools that help developers and creators get their favicons right the first time.
Our Mission
Favicons seem simple, but getting them right across every browser, device, and platform is surprisingly complex. We built Favicon.one to make this effortless.
Our tool generates every size and format you need, from the classic 16x16 to PWA-ready 512x512, with zero server-side processing. Your images never leave your browser.
Lightning Fast
Process images in seconds, entirely in your browser.
Premium Quality
Crisp, optimized output at every size.
User-Centric
Built by developers, for developers. And it's free.
Multi-Platform
Every format: ICO, PNG, SVG, Apple Touch, manifest.
Built by Creators, for Creators
Favicon.one is an open project. We believe the best tools are simple, fast, and respect your privacy. No accounts, no tracking, no upsells. Just a tool that works.
