Microsoft puts within our reach one of the small utilities, known as PowerToys, to make the image redimensioning process easier: Image Resizer. With this tool you'll be able to transform them to the size of your choice with a simple click of the mouse.
Yo use Image Resizer, all we have to do is select the image that we want to modify and right click on it. In the contextual menu we have to select Resize Pictures. After that we have to choose one of the preset sizes that the application offers or input a customized size.
By default, the application creates a copy to the size that you have chosen of the original image, even though it offers you the possibility to overwrite the redimensioned images.
Take Image Resizer into account when it comes to redimensioning images!
