I Built a Browser-Only Favicon Generator — Text, Emoji & SVG to ICO/PNG (136 Tests, Zero Dependencies)

Favicons are tiny but they matter. A sharp, recognizable 32×32 icon in a browser tab signals polish. But most favicon tools either require uploads, email sign-ups, or bloated JavaScript frameworks. I wanted something you can open, use in 10 seconds, and close — with nothing sent to a server.

So I built Favicon Generator: a single HTML file that converts text, emoji, or pasted SVG code into PNG files (16×16 through 180×180) and a multi-size .ico. Everything runs in the browser. Zero upload. Zero tracking.
