PIX to RB conversion is the process of transforming image files in the PIX format into the RB format so they can be opened, edited, or displayed by software that supports RB. This conversion re-encodes image data and may adjust compression and metadata to match RB's container and rendering requirements, preserving as much visual quality as possible.
