Why convert ICO to CR2?

Introduced in 1985 by Microsoft, ICO was great for its time. But CR2 (created in 2004 by Canon) 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.
