ICO to WebP Converter

About ICO to WebP

Converts an ICO file into a WebP image, keeping transparency while letting you decide how hard the encoder compresses. It suits developers who are moving an old set of icons into a modern asset pipeline that standardizes on WebP.

How to use it

1. Drag an .ico file into the dropzone, or click to select it.
2. Review the source preview.
3. Set the Quality slider between 10 and 100. It starts at 85.
4. Click Convert to WebP, then use Download WebP to save the result.

When to use it

• Adding an existing icon to a web project that serves only WebP images.
• Testing how WebP handles a flat, small graphic compared with PNG.
• Making an image of a site's favicon for a link preview or documentation.

Questions about ICO to WebP

Does WebP keep the icon's transparent corners?

Yes. WebP has an alpha channel, and no white fill is applied for this target, so the see-through parts of the icon remain transparent.

Is WebP a good format for tiny icons?

It is fine, but the gain is small. A 32×32 icon is already a few hundred bytes to a few kilobytes as PNG, and the WebP container overhead can make savings negligible.

Which quality should I use for flat colors?

Hard edges and single-color regions show ringing at low values, so keep the slider at 85 or higher. Lower values suit photographs better than icons.

Can every browser open the output?

All current major browsers display WebP. Older software and some email programs do not, so keep a PNG version for those situations.
