With the deadline of our annual photo contest soon approaching, we’ve been receiving a lot of questions about to how to resize images to 1200 pixels wide, while making sure the file is below 1 MB. We figured we would share this step-by-step process here, since a number of you might have the same question. In this example, the resizing procedure was done using Photoshop CS3, but most image-editing software offer a similarly working interface and functions. Just make sure to keep a copy of your original file on your computer before you start! As far as The World We Live In goes, this resized file is needed only for the judging process; a high-resolution file will be requested should your image be selected for publication.
Go to Image Size. Make sure that all the boxes are checked at the bottom of the window. Verify that the “pixels” option is selected in the drop-down menus, and enter the appropriate number of pixels for either the width or the height (the other parameter will automatically adapt proportionally).
When saving your image as a JPEG, a new window will appear with image quality options. If at 1200 pixels wide your image is still larger than 1 MB, you can choose a lower quality setting to reduce the size of your file, without affecting the display format of 1200 pixels.
