# imageoptimizer # imageoptimizer
imageoptimizer is a tool for bulk compression og JPG images. It will re-compress original images and replace them if the savings is imageoptimizer is a tool for bulk compression og JPG images. It will re-compress original images and replace them if the savings is
more than the requested percentage difference, default is 25%. By defaul it operated in a "dry run" mode where images are not replaced more than the requested percentage difference and optionally if the original file is bigger than a cefrtain size. By default it operates in a "dry run" mode where images are not replaced but individual and total savings are reported at the end, unless you supply the '-replace' flag.
