jpegoptim is a utility to optimize jpeg files.
It provides lossless optimization (based on optimizing the Huffman tables) and “lossy” optimization based on setting maximum quality factor.
It’s possible to compress a single file, multiple files at once, or all files within a directory.
jpegoptim is free and open source software.
Key Features
- Supports lossless optimization which is based on optimizing the Huffman tables.
- “Lossy” optimization where in addition to optimizing Huffman tables user can specify upperlimit for image quality.
- Experimental support for arithmetic coding.
- Support for progressive JPEGs. There are options to force all output files to be non-progressive or progressive.
- Uses memory (instead of temporary files) during optimization.
- Cross-platform support – runs under Linux, Mac OS X, Solaris, and Windows.
