Favicon Generator FAQ – Common Questions Answered

Quick Answer

What favicon sizes should I generate? Modern sites need at minimum: 16x16, 32x32, and 180x180 (Apple Touch Icon). The generator creates all standard sizes automatically from your source image.

Frequently Asked Questions

What input file should I use?

Use a square PNG or SVG at 512x512 pixels or larger for best results. The tool scales down from your source to create all required sizes.

What sizes are generated?

Standard output includes 16x16, 32x32, 48x48, 64x64, 128x128, and 180x180 (Apple Touch Icon). The package also includes an ICO file combining multiple sizes.

What is the ICO file for?

The ICO format is used by Windows and older browsers. Modern sites primarily use PNG favicons, but including an ICO file ensures compatibility with all environments.

How do I add the favicon to my website?

Place favicon.ico in your site root and add to your HTML head: link rel icon href /favicon.ico. For Apple Touch Icon, add link rel apple-touch-icon href /apple-touch-icon.png.

Can I use a transparent background?

Yes -- PNG favicons support transparency. Use a transparent PNG source to get transparent favicons. ICO files also support transparency in most browsers.

Will the favicon work in all browsers?

Yes -- the ICO file ensures compatibility with Internet Explorer. Modern browsers use the PNG versions which are included in the download package.

Troubleshooting

Favicon not showing in browser tab

Clear your browser cache and hard refresh (Ctrl+Shift+R). Browsers aggressively cache favicons. It may take a few minutes after deployment to update.

Favicon looks blurry

Use a higher-resolution source image (at least 512x512 pixels). The generator downscales from your source, so a larger input means sharper results at all sizes.

ICO file not recognized by server

Ensure you are serving the ICO file with the correct MIME type (image/x-icon). Some servers need explicit configuration for .ico files in their MIME type list.
