ImageOptim 1.4.0helps not just the developers and designers who expend the software , but also any of those users ’ exploiter , too . Let me explain : The free utility takes in your PNG , JPEG , and GIF files ( include GIF animations ) and optimizes them by shrinking their file size , often substantially . And it does so without affecting the image quality .
That ’s all it does , but that one feature makes ImageOptim tremendously useful to Web developers and iOS and Mac app developers . keep file cabinet size down by shrinking images without any loss in quality can promptly become a large trade : It saves bandwidth for everybody , and the numbers game can sum up quickly . ( Shave a few hundred KB off your democratic internet site ’s homepage , and you could savegigabytesof bandwidth over the course of a year .
ImageOptim ’s interface is Spartan but operable . retarding force picture onto its window or Dock icon , or tap the plus ( + ) button to select images from a standard Open dialog loge . The app immediately part optimize the image , using one or more of a slew of command - line simulacrum optimisation instrument : PNGOUT , AdvPNG , Pngcrush , extendedOptiPNG , JpegOptim , jpegrescan , jpegtran , andGifsicleare all seamlessly integrated . ImageOptim does n’t offer a whole pile of brainstorm into what it ’s doing , but you’re able to mouse - over an individual ikon on the list to see which tool the app is using to shrink the image .
Alongside each filename , ImageOptim lists its file sizing ( in bytes ) , and the percentage by which the file sizing was shrunk from the archetype . That numeral can depart widely depending upon your generator image , but I ’ve compressed some images more than 80 - per centum .
While I wish ImageOptim included a running total of just how much smaller all the files in a given batch are combined , that ’s at worst a minor oversight . The app works expeditiously , it ’s brain - dead simple to use , and it does just what it promises .
