Yes, it will! The WebP format natively supports transparent alpha channels. Your final WebP image will perfectly retain any clear background present in the original ICO file without adding ugly white or black boxes.

Yes, the file size reduction is often massive. Because ICO files contain multiple layers of varying image sizes, they can be surprisingly heavy. By extracting just one layer and applying modern WebP compression, the final file becomes incredibly small.

It depends entirely on where you set the slider! If you keep the slider at 85%, the file size drops significantly with almost no visible loss of clarity. If you push the slider to 100%, the image is saved using a "lossless" algorithm, meaning it stays mathematically perfect.

It is perfectly safe because nothing is actually uploaded to our servers! This tool leverages modern HTML5 Canvas technology to read and convert the icon entirely inside your own web browser. Your files never leave your device.
