Why convert ICO to WEBP?
Not all image formats age equally. ICO (1985) predates many of today's requirements, while WEBP directly addresses Modern web images — best compression. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. In practice, teams that make this switch rarely go back to ICO for this use case.
