PNG to ICO Converter

Convert a PNG image into a multi-resolution favicon.ico (16×16, 32×32, 48×48) — the universal favicon format. Free, instant, and processed entirely in your browser.

Why convert PNG to ICO?

PNG is great for favicons thanks to its transparency support, but some legacy systems require ICO format. Converting PNG to ICO gives you maximum compatibility.

Benefits

  • Legacy browser compatibility
  • Single file with multiple sizes embedded
  • Works on Windows, Mac, and Linux
  • Free and instant conversion

How to convert

  1. Upload your PNG file to the Favicon.one generator.
  2. The tool converts and outputs the ICO along with every other format you need, in a single ZIP.
  3. Download and drop the files into your website root.

The generator runs entirely in your browser. Your file is never uploaded to a server. It's converted locally and stays private.
