- What image should I use for a favicon?
- A square image works best, ideally 512×512 or larger so the small sizes stay crisp. A transparent PNG or an SVG keeps clean edges. Non-square images are centered and fit without cropping.
- What is the .ico file for?
- favicon.ico is the classic icon browsers look for at your site root. This one bundles 16, 32, and 48 px images in a single file so the browser can pick the size it needs.
- Which sizes do I actually need?
- A favicon.ico plus a 32 px PNG covers most browsers, and a 180 px apple-touch-icon handles iOS home screens. The 192 and 512 px sizes are used by Android and web app manifests.
- How do I add the favicon to my site?
- Put the downloaded files at your site root and paste the generated link tags into your page head. The HTML block on this page is ready to copy.
- Is my image uploaded?
- No. The resizing and .ico packaging happen on a canvas in your browser, so the image never leaves your device.
