There You Go

Unlike a Microsoft Word document, a PowerPoint presentation is meant to impress your audience through a balanced combination of images, animation, and text. However, if you’re files are getting too large, it might be wise to compress the size of those images. Luckily, Microsoft gives you various options to match how you plan on presenting your work, whether it be through the web, print, or in person.
