Drop an image to make favicons.

PNG · JPG · SVG · WebP · a square image works best · never uploaded

Crest turns one image into a complete favicon set — every PNG size a browser asks for, a real multi-resolution favicon.ico, a web manifest, and the exact HTML tags to paste into your page. A square logo on a transparent or solid background works best. Everything is generated in your browser and nothing is uploaded.

The favicon.ico bundles the 16, 32, and 48px versions in one file, which is what browsers fetch from your site root. The PNGs cover modern browsers, Apple touch icons, and Android/PWA home-screen icons; the manifest ties the 192 and 512px icons together for installable web apps. Put the files at your site root (or adjust the paths in the tags), and remember that browsers cache favicons aggressively — a hard refresh helps you see changes.
