How to Resize Images in Windows?

In today’s article, we will show you how you can resize a picture using different free tools. Most Windows versions also come with an image resizing tool, but it is not so reliable and doesn’t offer much control.

Resize Images with GIMP

GIMP (GNU Image Manipulation Program) is the most robust free photo editing tool, which can also be compared to the paid Adobe Photoshop photo editing tool. Resizing an image is a very basic function for a strong tool like GIMP, but still, we will use GIMP to illustrate how to resize images. It will help both advanced and novice users to resize image according to their need. If you are looking for a lighter and simpler tool for this purpose, skip this and check out the tools mentioned below.

To resize a picture with GIMP, you first need to add the picture inside the GIMP interface. You can directly drag-and-drop the picture inside the GIMP interface, or use the “Open” option in the “File” menu to select the photo from the directory.

None: Use this when you have a perfect image without any sampling.

Linear: It should be used when you have very small text in your picture.

Cubic: It is the standard way of scaling an image and best for most photos unless the photo is very small.

Sinc: It is quite similar to Cubic, but it uses “ringing” pattern instead of “blurring.” It works best for detailed graphics images.

As an average user, you should always use “Cubic” algorithm, and only change it if your image requires.

X and Y Resolution

You should not worry this, as it is used for printing purpose mostly. If you need to convert the picture to paper, then option can be used to spread “pixels” over “inches” or other measurement options. If you have no such intention, leave this option.

Resizing the Image

Now that you know what all these options mean, it should be easier to make your choice. For most users, the default options are perfect, and they should just provide “Width” and “Height” to resize the image. However, in rare situations, you can take advantage of other options as well.

To resize the image, provide the required Width or Height and the other factor will be adjusted according to your selection. For example, if you will enter 600 Width, 338 Height will be automatically selected, and vice versa.
