About jpegtran
jpegtran transforms JPEG files by rearranging compressed image data without fully decoding and re-encoding the picture. It can convert between JPEG variants, such as baseline and progressive encoding, and perform lossless rotations or other rearrangements. Avoiding a full decode-and-recompress cycle prevents additional image degradation. The command-line utility is useful for modifying JPEG orientation or representation while preserving the compressed image data. The supplied information does not enumerate all supported operations or metadata behavior. Some transformations depend on JPEG block boundaries, so exact results can vary with image dimensions. jpegtran’s role is lossless transformation of JPEG files. Lossless operations avoid the generation loss associated with repeatedly recompressing JPEG images.
