Why convert BMP to WBMP?

Introduced in 1988 by Microsoft, BMP was great for its time. But WBMP (created in 1998 by WAP Forum) offers uncompressed compression and 1-bit – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
