Why convert WEBP to WBMP?

A quick technical note: WEBP uses 24-bit while WBMP uses 1-bit. That difference matters most when your use case involves Legacy WAP mobile devices. 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.
