Every now and then while attempting to utilize a JPEG image you will discover that the image needs to have its size reduced. This is a common occurrence when trying to send images in emails and also when posting images to websites and blogs. Some people decide to use an alternate image instead of altering the size of their original JPEG simply because they don't know how to reduce the size. You don't have to be one of those people.
Power on your computer. Upload the image that you would like to resize to your computer. After uploading the image, save the image file with a .JPEG file extension.
Open your Photo editing software program. Three popular software programs are Windows Photo Gallery, Microsoft Paint and Adobe PhotoShop. Click on "File" and "Open" to locate the JPEG image you would like to resize.
Select the option to "Edit" your image. Choose the option to change the image size. Depending upon which image editing software program you are using, the wording will vary.
Reduce the size of your JPEG image to a size that is suitable for you. You can adjust the height and width of your image. You can also adjust the pixel size of the JPEG.
Save your JPEG image when you have finished resizing it. To avoid overwriting your original image, you should save your altered image under a different file name. By doing so, you can always go back to the original image, if the need arises.
