About Favicon Generator

Modern websites need favicons in multiple sizes: 16×16 and 32×32 for browser tabs, 48×48 for Windows shortcuts, 180×180 for Apple Touch icons, and 192×192 + 512×512 for PWA manifests. This tool generates all of them from a single upload and packages them in a ZIP file with the correct filenames. It also generates the HTML snippet you need to add to your <head>. Everything runs in your browser.

Frequently Asked Questions

What sizes do I need for favicons?

A complete favicon set includes: 16×16 and 32×32 for browser tabs, 48×48 for Windows, 180×180 for Apple Touch (iOS home screen), and 192×192 + 512×512 for Progressive Web Apps (PWA).

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and the Canvas API. Your files never leave your device — there is no server, no upload, no cloud processing.

What's in the ZIP download?

The ZIP contains all PNG sizes (favicon-16x16.png, favicon-32x32.png, favicon-48x48.png, apple-touch-icon.png, android-chrome-192x192.png, android-chrome-512x512.png) plus a favicon.ico file containing all three small sizes.

What image should I upload?

Upload a square image at least 512×512 pixels. PNG with a transparent background works best. Simple designs with bold shapes work better than photographs because favicons are very small.
