    Exactly what I was looking for. Made it much easier to archive large volumes of previously unoptimized images on backup drives. I especially appreciate the feature that allowed me to set a size threshold above which files should be compressed.

    One of (if not THE) best image compressors around. PLEASE use it and give this person some money!

    One of the best softwares out there to compress bulk images together up to the desired compression ratio. Thanks a lot.
