There are many situations where you might want to resize your photos or image files, especially if they are too big or heavyweight, like for sending them by e-mail or uploading them to a photo-sharing website. The best option in this situation is to resource to a specialized tool like Icecream Image Resizer, which allows you to resize lots of images with total accuracy and with just a few clicks.
The program's simple and straightforward user interface allows you to add any number of source image files either individually or by folders. All of them are listed on a special panel located at the left side of the program's main window, while on its right side there's another panel where you can define your target size. To do so, you can select from a list of predefined profiles that includes options like Email (1024x768), Facebook Timeline Cover (851x851), Desktop (varies according to your current desktop resolution), iPhone 4/5/6/6 plus, iPod, 320x200, HD 1080p (1920x1080), HD 720p (1280x720) and others, and in case you are not familiar with resolutions or pixel measures, you can simply select among Small, Medium and Large options. Of course, you can always type your custom width and height values if none of the provided profiles meet your requirements.
Next, you can select whether to force the program to keep the original aspect ratio of your images and to automatically recognize vertical ones. Finally, you can define the destination location for your resized images which can be the same as your source images, a subfolder inside it or a different folder you can specify. All that rests now is to press the "Resize" button for the program to start the process which, in general terms, is very fast.
In a nutshell, if all you want is to resize one or more of your images of photos quickly, easily and for free, Icecream Image Resizer could well be the perfect solution for you, however, if you need to apply any additional processing to your images, like renaming or rotating them, you will need to look for a more complex and probably paid tool.
