Reducing the Size of a PowerPoint File

Anya’s school work submission platform limits files to ten meg – when she embedded a dozen 3d images in a single presentation to create a seventy meg file? That was an easy fix – drop the 3d object down to a PNG. But her most recent presentation was just photos from the web, and it was just over the ten meg limit. Fortunately (or unfortunately in this case) the more recent Office document formats are already compressed … so you cannot just zip up the file to shrink it. We learned a quick way to reduce the size of a PowerPoint presentation.

Select one of the pictures in the presentation. On the “Picture Format” tab, find the “Compress Pictures” button.

If you know there is one really high-resolution picture (or a single picture where you cropped out most of it), selecting just that picture and leaving “apply only to this picture” checked makes sense. But, generally, I apply the compression to all images. Select a resolution that’s reasonable – we’ve used “Print” and reduced an eleven meg file to just over four meg. Using “Web” as the resolution reduced the file to just over a meg.

 

Did you know … you can insert 3D models in PowerPoint presentations?

Select “Insert” from the ribbon bar, then click the drop-down on “3D Models”. You can browse models from Remix 3D (“From Online Sources”) or models stored on your computer (“From a File”).

You can insert Filmbox (fbx), Object (obj), 3D Manufacturing (3mf), Polygon (ply), StereoLithography (stl), and Binary GL (glb) files.

STL files are commonly used when designing objects for 3D printing – here I’ve included a camera/telescope adapter.

Click on a 3D object and there is a rotation control

By changing an object’s orientation, you can use the “Morph” transition to rotate the object during your presentation. Right-click on the slide that contains your 3D object. Select “Duplicate Slide”.

Rotate the object on the new slide. Select “Transitions” from the ribbon bar, and select “Morph” as the transition.

When you play your presentation, the object will rotate as PowerPoint transitions between the two slides.

Now I know there aren’t a lot of uses for rotating 3D unicorns in business presentations, but manufacturers can embed 3D renderings of their products. Many architectural firms are providing 3D building designs that can now be included in PowerPoint presentations.

Did you know … your mouse can be a laser pointer in PowerPoint?

This works both in “Reading View” and when you are playing a presentation. To enable “Reading View”, select “View” from the ribbon bar and click “Reading View”.

To play your presentation, select “Slide Show” from the ribbon bar and click “From Beginning” (or “From Current Slide” to begin the presentation from the current slide).

Hold the CTRL key, then left-click and drag your mouse. You’ll see a red circle which can be used to draw attention to elements of your slide.

If you want a different color “laser”, select “Slide Show” from the ribbon bar and click “Set Up Slide Show”.

Click the drop-down next to “Laser pointer color” and select the desired color. Click OK.

Now when you hold the CTRL key, left-click and drag the mouse … now there’s a blue laser pointer.

 

 

Did you know … you can increase the maximum number of “undo” operations in PowerPoint?

I am a big fan of “undo” – highlighted something to copy it but missed the ‘ctrl’ part of ctrl-c? Undo! Editing an image and drew a line the wrong place? Undo! Change some verbiage and regret the modifications? Undo! (I’ll generally copy the stuff I’ve added into a new document before I start hitting ctrl-z {the keyboard shortcut for undo} and incorporate a few of the new ideas into the original text.) Occasionally, you run out of undo-able operations. If you are saving to OneDrive, SharePoint, or Teams, you can use the version history to get back to your original content. But did you know that PowerPoint allows you to increase the number of undo operations available?

Click “File” on the ribbon bar and select “Options”

Select “Advanced”. Under “Editing options”, you will see a maximum number of undos – this value defaults to 20.

You can increase it up to 150 – although higher numbers can adversely impact performance, so stick to a lower number unless you really want to undo a hundred operations!
