Shrink Pic is a practical tool that will resize your photos before you send them, whether you want to do so using email or an instant messaging client like MSN Messenger or Skype.
You don't need to learn any complicated tools to work with the program; it will launch from the task bar and make all of the necessary conversions automatically, while preserving the original image.
Shrink Pic is capable of reducing the size of your original by more than 90% without any loss in quality. You can set compression quality to the program default, or enter your own configuration.
Supports JPG, BMP, PNG, GIF, and TIF. You can configure it to convert any image you send to JPG.
