DNG output can introduce lossy compression. Keep a master file for repeated editing.
Converting JPG to DNG decodes the source image and writes a DNG output. Use this route when DNG is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on DNG compression: lossless_or_lossy_depends.
Choose conversion targets based on DNG compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: Exif, JFIF, XMP, ICC, IPTC.
Broad raw software support compared with many proprietary raw formats.
