Do you have large document files that you are trying to send to colleagues or upload to an online site such as myLesley, VoiceThread, OneDrive, or SharePoint? In many cases, compressing your files, images, and videos will help to reduce your overall file size and meet size restrictions.

As a best practice, when uploading large files you will want to make sure that you are using a fast, stable Internet connection.

Documents (Microsoft Word)

You can reduce the file size of your document by compressing images. The compression options reduce both the file size and image dimensions based on how you intend to use the picture, such as viewing on screen or in an e-mail message. You can compress all images in the file or just the ones that you select.
