The favicon can be in any image format (ico, png, jpg) and the most recommended design and style of your website favicon is to have it look good on both light and dark theme colors.
To add the favicon prepare an image at least around 32px in width and height and the format can be any image format. Once you have that ready you can add the following code in your "head" HTML tag.
