Tips for best results

A few things to keep in mind:

• Favicons and icons are usually square. If your image isn't square, crop or resize it first for best results.
• Include 16×16 and 32×32 at least for favicons; 48×48 and 256×256 help for Windows and high-DPI.
• Simple, high-contrast images work best at small sizes.
• If the tool offers a crop step, use it to centre the important part in a square.
• You can also drag .jpg files here; the tool will process them the same way.
• Test your favicon in several browsers and on mobile after uploading.
• Some systems accept PNG for favicons; ICO is still widely used and holds multiple sizes.
