Question 1

What image formats can I upload?

Accepted Answer

You can upload PNG, JPG, JPEG, SVG, and WebP images. The tool will scale them to each selected size using the Canvas API.

Question 2

Why are the files saved as PNG instead of ICO?

Accepted Answer

True ICO files require a complex binary format. For simplicity, this tool generates PNG files at each selected size. Modern browsers fully support PNG-based favicons — just add them to your HTML with the correct link tag.

Question 3

Which sizes should I choose for a favicon?

Accepted Answer

For basic browser tab icons, 16×16 and 32×32 are sufficient. For Apple touch icons, use 128×128 or 256×256. For a complete favicon setup, generate all sizes.

Question 4

Is my image processed on the server?

Accepted Answer

No. All image processing is done locally in your browser using the Canvas API. Your image is never uploaded anywhere.

Question 5

How do I add the generated favicon to my website?

Accepted Answer

Place the downloaded PNG file in your project root and add a link tag to your HTML head: <link rel='icon' type='image/png' href='/favicon-32x32.png' sizes='32x32'>.
