Why convert ICO to WBMP?

If you work with ICO regularly, you've probably hit compatibility walls. WBMP was built for exactly this gap – 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.
