Converting CR3 to JP2 does not create transparency by itself.
Camera raw conversion requires decoding, demosaicing, white balance, tone mapping, and encoder choices.
Converting CR3 to JP2 decodes the source image and writes a JP2 output. Use this route when JP2 is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on JP2 compression: both.
Choose conversion targets based on JP2 compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: Exif, Canon MakerNotes, XMP sidecars.
Used in preservation, medical, geospatial, and some archival workflows.
