• Creating a favicon.ico for a website from a logo.
• Producing a Windows application or shortcut icon.
• Generating a multi-resolution icon file from a single source image.

PNG to ICO Converter: limits and things worth knowing

• An ICO file can contain several resolutions in one file — commonly 16, 32 and 48 pixels — which is why favicon.ico remains the most reliable fallback across browsers.
• Start from a square source. A non-square PNG will be padded or distorted, and neither looks right at 16 pixels.
• Design for the smallest size that will actually be shown. A detailed logo becomes an unreadable smudge at 16 pixels, so favicons usually need a simplified mark rather than the full lockup.
• PNG transparency is preserved, which matters because favicons sit on browser chrome of unpredictable colour.

Is it private and secure?

Your privacy is built in. PNG to ICO Converter does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
