What sizes are included in the .ico?

Six square sizes (16, 32, 48, 64, 128 and 256 px) are packed into a single ICO, so browsers and Windows can pick the right one for each context.

My image isn’t square — will it be stretched?

No. Non-square images are centred and scaled to fit inside each square with transparent padding, so nothing is distorted. For the crispest favicon, start from a square image.

Where do I put the favicon?

Save it as favicon.ico in your site’s root, or reference it with a tag. Most browsers also pick up a root /favicon.ico automatically.

Are my files uploaded to a server?

No. The whole conversion runs in your browser using your device's own processor. Your files are never sent anywhere.

A favicon is the little icon shown in browser tabs and bookmarks, and it needs to be an ICO file with several sizes packed inside. This builds one from your image — 16, 32, 48, 64, 128 and 256-pixel versions — entirely in your browser.
