Tool usage guide
Easily convert your ICO icon files into the modern, high-performance WebP format while maintaining transparency and optimizing image quality for web use.
Background
A developer has a 256x256 ICO file used for a desktop app and needs to use it as a favicon on a website.
Problem
The original ICO file is too large and not optimized for web browsers.
How to use
Upload the ICO file, set the extraction size to 32x32, and set the quality to 85.
{"extractSize": "32", "quality": 85}Outcome
A lightweight 32x32 WebP file that loads instantly as a browser favicon.
Background
A designer needs to convert a high-resolution logo icon from ICO to WebP without losing any visual detail.

Standard compression might introduce artifacts in the icon's sharp edges.
How to use
Upload the ICO file and enable the 'Lossless Compression' option.
