ICO files are Windows icons and website favicons, and one file often holds several sizes. Icons are limited to 256×256 pixels and must be square. Choose WebP to make images load faster on a website while keeping transparency.

ICO to WebP settings

Use the quality slider to balance size against detail; 80 to 90 percent is a good default for WebP. You can also cap the width and height, which resizes large photos in the same step.

Frequently asked questions

Will the WebP lose quality?

WebP uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the ICO original.

Is transparency kept when converting ICO to WebP?

Yes. WebP supports transparency, so transparent areas in your ICO stay transparent.
