What is Image Favicon?

Favicon Generator turns a single source image into a complete bundle of favicons at all the sizes modern browsers and operating systems need (16, 32, 48, 64, 128, 180, 192, 512 px), plus the .ico container for legacy browsers.

How to use Image Favicon

  1. Drop a square image (PNG works best, ideally 512×512 or larger).
  2. Click "Generate Favicons".
  3. Inspect the bundle preview.
  4. Download the ZIP containing every size and an HTML snippet to paste into your <head>.
