About OhMyIcon

OhMyIcon is a free, browser-based generator for favicons and mobile app icons. Every size, every format, every meta tag — produced locally in your browser. Your source images never leave your device.

Who runs it

OhMyIcon is operated by an independent web developer based in South Korea. The site was built to scratch a personal itch: existing favicon generators upload your image to a third-party server, force a sign-up, or omit half the sizes you actually need. I wanted one tool that produced the full set, ran locally, and explained why every file in the ZIP exists.

How it works

The .ico encoder is a hand-written ~80-line module that builds the binary container directly from PNGs in JavaScript. Image resizing happens on a Canvas. ZIP packaging uses JSZip. Nothing is uploaded.

How it's funded

The site shows ads served by Google AdSense. Ads are clearly labeled and never inserted in places that interfere with the tool itself. Revenue covers the domain registration and a small amount of time spent maintaining the code.
