Questions
What sizes does the favicon generator produce?
The tool generates favicons at 16x16, 32x32, 48x48, 64x64, 128x128, and 256x256 pixels, covering the most common sizes used by browsers, operating systems, and app stores.
What image format should I upload?
You can upload any common image format such as PNG, JPEG, SVG, or WebP. Square images work best since favicons are square; non-square images will be scaled to fit.
How do I add the generated favicon to my website?
Download the favicon files and place them in your site root directory. Add a link tag in your HTML head like <link rel="icon" href="/favicon.png" type="image/png"> for each size you want to support.
Does the favicon generator create ICO files?
The tool generates PNG favicons, which are supported by all modern browsers. If you need the legacy ICO format for older browsers, you can convert the generated PNG using a dedicated ICO converter.
Is the favicon generator free and does it work offline?
Yes. The tool is completely free and runs in your browser using the Canvas API. Once the page loads, no internet connection is needed.
