When I want to quickly email or upload images in Windows I would rather not have to load a full software package. The easiest way that I have found resize images in Windows is Image Resizer for Windows.
You really can’t get any easier than Image Resizer for Windows. After installing Image Resizer all you need to do is select the image that you want to resize in Windows Explorer. That will pull up the “context menu” and you will see a new option that says “Resize pictures”. After clicking on “Resize pictures” you will have see the following options pop up.
You can then easily choose what size you want to scale the image to and click on “Resize”. You can then see the new image that has been created, usually under the original image.
It really doesn’t get any easier than that, so there you go. Just download Image Resizer for Windows and you are ready to go …
