About GenFavicon

David Kim
Frontend Developer · Built GenFavicon in 2026

I'm David. I build and maintain websites — mostly WordPress, some static, a few React projects. One thing every single site needs is a favicon. And every time I needed one, I found myself on a generator site from 2015 that hadn't been updated since the Obama administration, or a "free" tool that wanted my email before giving me the file.

"A favicon is 256 bytes. The fact that I need to upload my client's logo to a server just to resize it to 16×16 pixels is absurd. So I built GenFavicon."

How It Works

Everything runs in your browser using the Canvas API. Upload an image — PNG, JPG, SVG, WebP — and your browser renders it at all six standard favicon sizes simultaneously. Nothing is uploaded to a server because there is no server. You can disconnect your internet and the tool keeps working. Try it.

Why Free

I manage dozens of client websites. I use this tool myself. Charging for a favicon generator would be like charging for a ruler — it's a basic tool that should be free. The site runs on Cloudflare Pages (essentially free) and is supported by non-intrusive ads.
