• Creating a Windows icon from a photographic source.
• Producing an icon file when the only source available is a JPG.

JPG to ICO Converter: limits and things worth knowing

• JPG has no transparency, so the icon will have a solid background. For a favicon that needs to sit on any colour, start from a PNG with an alpha channel instead.
• JPEG artefacts become very visible once an image is scaled to 16 or 32 pixels. A vector or high-resolution PNG source produces a noticeably cleaner icon.
• Photographs rarely work as favicons at all — at 16 pixels there is room for a shape and a colour, not for an image.

Is it private and secure?

Your privacy is built in. JPG 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.
