Better JPEG photo editor

BetterJPEG is a JPEG photo editor specifically designed to avoid recompression loss when editing photos. BetterJPEG takes advantage of the fact that JPEG images consist of a number of small independent blocks and does not recompress blocks that don't have to be changed, retaining original quality and sampling settings.
The list of lossless operations supported by BetterJPEG covers the essentials of digital photo processing, which, in combination with intuitive GUI and state-of-the-art image processing algorithms, makes it an indispensable tool for digital camera owners.
