Why convert JPEG to DIB?

Introduced in 1992 by JPEG Committee, JPEG was great for its time. But DIB (created in 1990 by Microsoft) offers uncompressed compression and 24-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.
