CR3 does not support alpha transparency. Transparent JP2 areas must be flattened onto a background color.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting JP2 to CR3 decodes the source image and writes a CR3 output. Use this route when CR3 is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on CR3 compression: depends.
Choose conversion targets based on CR3 compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: color space, IP rights, XML boxes, JP2 boxes.
Raw converter support depends on camera model and decoder version.
