Icon files rarely work outside Windows contexts; ICO to WebP conversion extracts the biggest embedded image as a lightweight modern web graphic. Alpha transparency survives, so the icon keeps its clean cutout on any page background.

Why convert ICO to WEBP?
- Show app or site icons inside web UIs without serving the crufty multi-image .ico container.
- Cut bytes on icon-heavy pages — WebP encodes small graphics tighter than PNG or GIF.
- Standardize scraped or archived favicons into one modern format for galleries and audits.
Tip: Remember the source ceiling: a favicon that only contains 16- and 32-pixel images cannot yield a large sharp WebP, whatever settings you choose.
