Generate ICO Favicon from PNG Image Free
Overview
Browsers look for favicon.ico in the root of your site. A proper .ico file contains multiple sizes (16x16 for browser tabs, 32x32 for taskbar pinning, 48x48 for Windows shortcuts). Upload your PNG logo and the tool generates a single multi-size .ico file that covers all use cases.
How to Use This Tool
Upload your PNG logo (square images work best; rectangular logos are centered with padding). Select the sizes to include (16x16, 32x32, 48x48 are standard). Click Generate ICO. Download favicon.ico and place it in your site's root directory.

What size should a favicon PNG be before converting?
Start with at least a 256x256px square PNG. The converter downscales to the selected sizes. Larger source images produce sharper small-size outputs because the downscaling algorithm has more pixel data to work with.
Do I need an .ico file or can I use a PNG favicon?
Modern browsers accept PNG favicons via a link tag: <link rel='icon' type='image/png' href='/favicon.png'>. But .ico format supports multiple sizes in one file and works in older browsers (IE11 and below) without a link tag.
How do I add the favicon to my website?
Place favicon.ico in your site root directory. Browsers automatically look for it at yoursite.com/favicon.ico. Optionally add <link rel='icon' href='/favicon.ico'> in the HTML head for explicit referencing.
