Camera raw conversion requires decoding, demosaicing, white balance, tone mapping, and encoder choices.
Converting 3FR 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.
