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 JPEG editing supported includes rotation, crop, brightness and color adjustment, date/EXIF info/text insertion, red eye removal, conversion to grayscale, and more..
Better JPEG plug-in for Adobe Photoshop is a tool designed to ensure better decoding of JPEG images and to avoid recompression loss when editing and resaving JPEG images in Photoshop. The plug-in 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. Thanks to the advanced JPEG decoding algorithm (DCT reconstruction), JPEG images open with BetterJPEG show fewer artifacts than the ones open with Photoshop's Open command.
