Question 1

What is a favicon and what size should it be?

Accepted Answer

A favicon is the small icon displayed in browser tabs, bookmarks, and address bars. The standard size is 16×16 pixels, but modern browsers also use 32×32 and 48×48 for higher-resolution displays. Apple devices request a 180×180 apple-touch-icon. This tool generates all common sizes.

Question 2

Should I use ICO or PNG for my favicon?

Accepted Answer

ICO format is the most broadly compatible and can bundle multiple sizes (16×16, 32×32, 48×48) in a single file. PNG favicons are supported by all modern browsers and are easier to work with. For maximum compatibility, use an ICO file linked as <link rel="icon" href="/favicon.ico"> and also provide a PNG for modern browsers.

Question 3

How do I add a favicon to my website?

Accepted Answer

Download the favicon file and place it in your website's root directory. Add the following to your HTML : for ICO, or for PNG. In Next.js, place a favicon.ico in the /app directory and it is handled automatically.

Question 4

Can I create a favicon from an emoji?

Accepted Answer

Yes. Type any emoji into the text field and the tool renders it centered on your chosen background color. Emoji favicons are a popular minimalist choice — they render crisply and are immediately recognizable even at 16×16 pixels.

Question 5

Does the tool support transparent backgrounds?

Accepted Answer

Yes. You can set the background to transparent when exporting as PNG. Note that ICO files can support transparency, but rendering varies across older browsers. For transparent favicons, PNG is the recommended format.
