Create a single `.ico` file that packs multiple sizes (16px, 32px, 48px). No need to manage separate files for basic browser compatibility.

That is the intended behavior of the ICO format! Think of an `.ico` file like a ZIP file for images. It contains multiple layers. When you select 16px, 32px, and 48px, our tool generates all three images and packs them inside that single `.ico` file. Browsers will automatically pick the correct size.
We support **PNG, JPG, JPEG, WEBP, and BMP**. For the best quality favicons, we highly recommend using a **PNG with a transparent background**. If you use a JPG (which doesn't support transparency), your icon will have a solid square box around it.
1. Rename the file to `favicon.ico`. 2. Upload it to your website's root directory. 3. Add `` to your HTML head.
