Quickscale is designed to let you resize a large amount of pictures to a desired size and format. Now, why would you want to do that? For example, if you wish to share your holiday photos with family and friends, you can either send them by e-mail or put them somewhere on a website. The problem is that these pictures are usually far too large, have immense resolutions, and take far too long to send.
Meet Quickscale: select the images, choose a desired resolution, and Quickscale scales them down for you. QuickScale can read from, and write to almost every format supported by your Mac OS (including jpg, png, gif, and more).
