Mass Image Compressor for Mac

Mass Image Compressor (MIC) allows users to optimize, resize, convert and watermark images in bulk with ease. Drag and drop one or more images and videos — or an entire folder — to compress, adjust quality, and select output formats for the bulk operation. MIC also offers live compression preview: select any image from the gallery to test your settings before starting the batch operation.
