How do I convert WebP to ICO?

Upload your WebP 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 WebP to ICO lose quality?

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

Will the ICO keep the transparent background?

Yes. ICO supports smooth, partial transparency, so transparent areas stay transparent.

Will the animation be kept?

No. ICO can’t hold animation, so an animated WebP is saved as its first frame.

WebP was designed by Google for the web. Google measured lossy WebP files at 25–34% smaller than comparable JPGs, and WebP also handles transparency and animation.

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 WebP 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 WebP to ICO?

Transparent areas stay transparent: ICO supports smooth, partial transparency just like WebP.
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.

What to expect when converting WebP to ICO

ICO can’t hold this animation, so an animated WebP is saved as its first frame.
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.
