BetterJPEG is a JPEG editor specifically designed to avoid recompression loss when editing and resaving JPEG images. 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.
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.
- Lossless transformations - rotation, flip
- Lossless crop (free, fixed aspect, fixed size, predefined and user-defined aspects and sizes), composition guidelines (diagonals, golden mean, rule of thirds)
- Lossless brightness correction
- Lossless color correction
- Highly customizable lossless date/EXIF info/text insertion (position, font, size, color, background, language, format, etc.).
- Advanced lossless red eye removal (anti-aliasing, adjustable size, sensitivity, darkening).
- Copy/Paste to external editor and back for local retouching without full recompression (lossless)
- Resize JPEG images
- Batch and fast one-by-one image processing
- Macro actions
- Multi-level Undo/Redo
- Metadata preservation
- Compression optimization
