What does Favicon Generator do?

Websites and apps need icons in several sizes, and exporting each one by hand is repetitive. This generator produces the common browser and app icon sizes from a single square master image.

Icons are generated locally in the browser, so your source image is never uploaded.

Generate common favicon and app icon sizes at once.
Start from one square master image.
Export locally without a server or sign-up.

Common use cases

Adding a favicon to a new website
Generating app icon sizes
Refreshing a site's icon set
