How to Resize an Image

With the technology we have now, it's so easy to take photos that it's not unusual or strange to have hundreds of pictures stored. Storage does become a problem, though, because the file size of a photo gets bigger as the camera gets better. When you resize an image, you can do more than just crop it. You can also change the pixels to make the file smaller. If you want to send a lot of photos to someone but the file size is too big, you'll need to compress the photos before you can send them. This is a good time to resize images. You can change an image's picture and file size to fit your needs if you have the right tools. This article shows you how to resize an image on different devices including Windows, Mac, Android, and iPhone. It's simple.
