About the WebP to ICO Converter
Logos downloaded from websites are often WebP now, but Windows icons and favicon.ico need the ICO container. Converting directly keeps the WebP's alpha channel in every icon size.
The WebP is decoded by your browser (all current browsers), alpha included; animated WebPs give their first frame.
The ICO is assembled by our own encoder: each size is rendered from your image with high-quality stepped downscaling, then stored either as a PNG entry (compact; Windows Vista and later) or as a classic 32-bit BMP entry with an AND transparency mask (works on every Windows version), behind a standard ICONDIR directory.

Things to know
- Animated WebPs. Only the first frame is used; ICO can't animate.
- Lossy edges. Lossy WebP logos may have soft or haloed edges that become visible at large icon sizes.
