How to Generate an ICO Favicon

1. Prepare your logo file. (We highly recommend a square, high-resolution .png file with a transparent background).
2. Upload the logo into the converter's dropzone.
3. Confirm the conversion settings and process the image.
4. Download the favicon.ico and upload it to your website's root directory.

Frequently Asked Questions

Why not just use a PNG as a favicon?

While modern browsers absolutely support using a clean PNG as a favicon, .ico remains the absolute gold standard fallback and offers the unique advantage of packaging multiple resolutions into a single file payload.

Is my icon squished?

If your underlying uploaded image wasn't a perfect 1:1 square, the output might look stretched. Always crop your source logos to a perfect square aspect ratio before wrapping them into an ICO.
