Prepo is a small Mac application that helps you resize and export your app icons and artwork to various image formats. This program might prove to be of great use whenever you need to change the icon for an app installed on your iPhone or iPad.
The app brings an intuitive interface, easy-to-configure output settings, and a simple way to share app icons via e-mail or Facebook. When it comes to preparing your artwork files, you can convert your images to a wide range of output formats and change the resolution of your pictures with minimum effort.
Once you finish altering the icons and artwork, you can export your results to any local folder within your Mac. You can also create duplicates for the processed files, move them to other folder locations or rename the images if necessary.
The only thing that bothers me about working with Prepo is that you need to upgrade the app to Plus+ version in order to preview your designs and screen in context on your device. However, you can do that directly from the program's interface and you get to pay a reasonable price.
To conclude, Prepo is a helpful app that provides you with a solution when you wish to prepare icons for apps installed on your iPhone or iPad. The program is very simple to use, offers you immediate results, and supports a wide range of image formats.
