Microsoft Paint users

Microsoft Paint users can use the Stretch/Skew option under the Image drop-down menu; 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 users

  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.
