How to Compress File Sizes

In submitting documents online, file size can be a major issue. Below is a number of steps that can be taken using freely available online services.

Reduce the file size of a picture in Microsoft Office

You can reduce file size and save disk space on your computer by compressing pictures in your document. The compression options reduce both the file size and picture dimensions based on how you intend to use the picture, such as viewing on screen or in an email message. You can compress all pictures in the file or just the ones that you select.

These features are not available in Office for the web, only the desktop versions of Microsoft office.

  1. With your file open in your Microsoft Office application, select the picture or pictures that you want to compress. If you do not see the Picture Tools – Format tab, make sure that you selected a picture. You may have to double-click the picture to select it and open the Format tab.
  2. To compress the selected pictures only and not all of the pictures in the document, select the Apply only to this picture check box.

Help Guides are available from Microsoft regarding compression at the links below. These guides cover PC and macOS interfaces.
