    About the Favicon Generator

    Every site needs a favicon. Modern sites need eight favicons for different platforms (browser tab, iOS home-screen, Android home-screen, desktop shortcut, PWA splash). Doing this by hand means opening an image editor 10 times. This tool generates every size from one source in 5 seconds and emits the HTML + manifest.json you paste into your <head>.

    Features

    How it works

    1. Upload your source image (SVG or ≥512px PNG).
    2. Choose background + optional rounded corners.
    3. Click 'Download all' and drop the files at your site root.
    4. Paste the HTML snippet into your &lt;head&gt;.

    Frequently asked questions

    What size should my source image be?

    +

    SVG is best — infinite resolution. If PNG, use 1024×1024 or 512×512 square; anything smaller scales up badly.

    Where do I put the downloaded files?

    +

    At the root of your site (e.g. next to your index.html). The HTML snippet references them from the root path.

    Do I need all 10 sizes?

    +

    Technically no, but modern browsers + iOS + Android all want different sizes and you avoid ugly fallbacks by shipping everything. Total payload is under 20 KB.

    Can I generate .ico files?

    +

    Not yet — modern browsers accept PNG natively, so favicon.ico is optional. The standard favicon-32x32.png served at the root works for most setups.

    Are my images uploaded anywhere?

    +

    No — everything runs in your browser via canvas.
