Image Optimization Guide

These instructions are based on using Adobe Photoshop CC, which is available for university Faculty and Staff.

Cropping and Resizing

Crop your photo by first clicking on the Crop icon. Make sure it is set to crop by Ratio and then put in the ratio at which you'd like to crop the photo (ex: 1600 px x 900 px).

Image Crop with Ratio

Drag the image to select where you'd like it to be cropped at this ratio. Check the checkmark to confirm the crop.

Set Ratio and click the checkmark

In the menu, go to Image and select Image Size.

Image Size

Set the resolution to 72. Enter the size you'd like to crop the photo to (see our guide to sizing), and make sure resample is set to Bilinear.

set resolution, size, and bilinear

Click OK.

Optimizing and Saving for Web

Next you'll need to save your resized and/or cropped photo and optimize it for the web.

In the menu, go to File and click Save for Web. (In some Photoshop versions, this has moved under File > Export > Save for Web.)

File, Save for Web

Make sure that it will save as a JPEG and at the top of the box where it says Quality, set it to anywhere between 100 and 80, depending on that it says the file size is in the bottom left of the window. Using the scroll bar, look under the image in the bottom left corner and as you scroll it lower try to get it as close to 300K as possible (try for no lower than 60). 

If you're resizing an image for a bio page you won't have to adjust the Quality, as the photo at 255px by 300px will already be small enough to be considered optimized. Skip this step and continue to the next.

Click Save and then save it to your computer with a clear file name, with no spaces or special characters in it (ex: depaulstudents.jpg).

Now you are ready to upload it to your SharePoint site's images library.
