What size should a favicon be?

Supply one square source at 512×512 or larger and let every size be generated from it. The set needed is 16, 32 and 48 in the .ico, 180 for iOS, and 192 and 512 for Android and PWA.

Do I still need an .ico file?

It remains the most broadly compatible option and is what older browsers look for at the site root, so it is included. Modern browsers will happily use the PNGs.

Why does my favicon look blurry?

Usually because a single large PNG is being scaled down by the browser rather than a purpose-made small version being served. Generating each size separately is the fix.

Can I use a non-square image?

It will be padded to a square, which usually looks wrong. Crop to a square first.

Generate a complete favicon set

A favicon is no longer a single 16-pixel square. Browsers ask for one size, Android home screens another, iOS wants a 180-pixel apple-touch-icon, and Google uses a square icon of at least 48 pixels beside mobile search results. This tool renders every one of those from a single source image and hands them back with the HTML you need to reference them.

Start from something square

A favicon is displayed as a square, so a wide photo will either be cropped or padded. Simple, high-contrast artwork works best: at 16 pixels there is room for a letter or a bold shape and nothing more. Detail that looks good at 512 disappears entirely at favicon size.

Frequently asked questions

Which sizes do I actually need?

For most sites: 32 and 16 in the .ico, a 180-pixel apple-touch-icon, and 192 and 512 PNGs for the web manifest. The pack contains all of them plus the markup to link them.

Is the .ico a real ICO file?

Yes. It is assembled as a genuine multi-resolution ICO containing 16, 32 and 48 pixel images, which is what older browsers and Windows expect.
