How do I convert JPG to ICO?

Upload your JPG file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting JPG to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

JPG or ICO: which should I use?

Use JPG for photos you share, email, print or upload. Use ICO for website favicons and Windows app or shortcut icons. Keep in mind the main drawback of ICO: icons are square and at most 256 × 256 pixels.

JPG is the standard format for photos. It shrinks files by discarding detail the eye barely notices, which suits photographs but blurs text and sharp edges.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Is the JPG to ICO converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

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.
