Frequently Asked Questions

Which size is extracted from multi-size ICO files?

This tool automatically extracts the largest resolution from the ICO file. For example, if your favicon.ico contains 16×16, 32×32, and 256×256 versions, the 256×256 version will be extracted and converted to WebP for maximum quality.

Is transparency preserved during conversion?

Yes! WebP's full alpha channel support means transparency is perfectly preserved. If your ICO has a transparent background, the WebP will maintain it as documented by Google WebP specifications.

Is WebP widely supported?

Yes! WebP is now supported by all modern browsers including Chrome, Firefox, Safari, and Edge. Check WebP browser support for detailed compatibility information.

Is my data safe when using this converter?

Absolutely! All conversion happens in your browser using JavaScript and the Canvas API. Your ICO files never leave your device, ensuring complete privacy and security as recommended by W3C security guidelines.

What quality setting is used for WebP?

We use 90% quality for WebP conversion, which provides excellent image quality while still maintaining WebP's compression advantages. This setting balances visual quality with file size optimization.

Yes! You can use our WebP to ICO converter to convert your WebP image back to a multi-size ICO favicon. You can also use our ICO to PNG converter if you need a more universal format.
