When posting a picture online or sending a picture in an e-mail, it may be necessary to resize the image to keep the image small in size and dimension. Below are the steps on how to rotate images in each of the major image editors with links to web pages that can resize images.

Tip

If you want to only use a portion of the image and not resize the full image, crop the image.

IrfanView

  1. Open the image in IrfanView.
  2. Click Image and then Resize/Resample.
  3. Either specify the size in pixels you want to make the image or click the half button to cut the image size in half.
Note

Each time the half button is pressed, it will reduce the image size in half.

The GIMP

  1. Open the image in The GIMP.
  2. Click Image at the top of the image tool bar.
  3. Click Scale Image.
  4. In the Image size, specify the dimensions you want to use and click the Scale button.

Microsoft Paint

Microsoft Paint users can use the Resize option in the Image section on the Home tab. However, this option often degrades the overall quality of the image. We suggest users use one of the above programs or solutions for resizing their images instead.

Adobe Photoshop

  1. Open the image in Adobe Photoshop.
  2. Click Image.
  3. Click Image size.
  4. Specify the size of the image you want to have. It's often easier for most users to specify the size using pixels as the measurement.
