Why convert DIB to JPEG?

The main issue with DIB is huge file sizes (uncompressed data). Converting to JPEG fixes this by providing native browser rendering without plugins. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
