100% client-side — your image never leaves your device

Favicon generator,
without the upload.

Turn an image or SVG into favicon.ico and app icons — right in your browser. Drag, drop, done.

How it works

  1. 1

    Drop an image

    Use a square PNG, JPG, WEBP or SVG for the sharpest result — decoded locally, no upload.

  2. 2

    Tune it

    Pick a background (transparent or a color) and set your app name for the web manifest.

  3. 3

    Download the package

    Get a zip with favicon.ico, app icons, site.webmanifest, and the <head> snippet to paste in.

Frequently asked questions

Is my image uploaded to a server?+

No. The icons are rendered and packaged entirely in your browser. Your image never leaves your device.

What's in the download?+

A zip with favicon.ico (16/32/48), apple-touch-icon.png (180), icon-192.png, icon-512.png, a site.webmanifest, and a snippet.html containing the <link> tags for your page's <head>.

What image should I use?+

A square image works best. SVGs are re-rendered crisply at every size; raster images are scaled down. Add a background color if your image is transparent and you want a solid icon.

Is it free?+

Yes — free, no signup, no watermarks.
