Why convert PNG to CR2?

Introduced in 1996 by PNG Development Group, PNG 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.

Transparent areas will be filled with white background
