Why convert JPG to ICO?
- One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.
- Browsers show the ICO as your site’s tab and bookmark icon when you save it as favicon.ico.
What to expect when converting JPG to ICO
- Icons are square, so a non-square image is centred on a transparent square. Sizes larger than your image aren’t created, so start from at least 256 × 256 pixels.
- Your original JPG file isn’t changed: you download a new ICO copy.
