Why convert WEBP to BMP?

Not all image formats age equally. WEBP (2010) predates many of today's requirements, while BMP directly addresses Uncompressed images on Windows. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. The conversion itself takes seconds — the benefits last much longer.
