Re-encoding drops metadata. EXIF, GPS coordinates and colour profiles do not survive, which is a privacy gain if you are posting photos and a loss if you rely on camera data or embedded copyright. Rotation is read from the file first, so portrait photos stay portrait. Converting an image with transparency to JPEG fills the transparent areas with white, since JPEG has no alpha channel.
