DNG does not support alpha transparency. Transparent JP2 areas must be flattened onto a background color.
DNG output can introduce lossy compression. Keep a master file for repeated editing.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting JP2 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: color space, IP rights, XML boxes, JP2 boxes.
Broad raw software support compared with many proprietary raw formats.
