Why convert WBMP to ARW?

Introduced in 1998 by WAP Forum, WBMP was great for its time. But ARW (created in 2006 by Sony) offers lossless RAW compression and 14-bit per channel – 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. The conversion itself takes seconds — the benefits last much longer.

This format requires a WebAssembly decoder — allow a moment for library loading
