Utilities for archiving photos for saving to long term storage or serving over the web. The goals are: use a common, well supported format (JPEG), minimize storage space and cost, identify duplicates / similar photos.
The following utilities are part of this project: jpeg-archive: compress RAW and JPEG files in a folder utilizing all CPU cores. jpeg-recompress: compress JPEGs by re-encoding to the smallest JPEG quality while keeping perceived visual quality the same and by making sure huffman tables are optimized. This is a lossy operation, but the images are visually identical and it usually saves 30-70% of the size for JPEGs coming from a digital camera, particularly DSLRs. jpeg-compare: Compare two JPEG photos to judge how similar they are. jpeg-hash: Create a hash of an image that can be used to compare it to other images quickly.

JPEG Archive is a tool to compress images based on perceived image quality to reduce file size while maintaining certain quality level.
This is a best choice if:
your workflow includes (batch or occasional) image processing and/or publishing;
you are looking for a scriptable lossy image compression tool similar to those used by social networks and image hosting providers;
you are web developer looking to optimize website loading speed by compressing images.
Similar algorithms and options are available that provide different quality-to-comprression-ratio trade-offs.
And it's free and open source.
The only downside is that it have only command-line interface.

Perfect. With default settings, cannot tell the difference with original. Saves a lot of space on images coming out straight of a camera and keeps all metadata. Ideal for archiving (along with a batch file)
