When you open and then save an existing Microsoft PowerPoint presentation, the file size of the presentation may increase by several megabytes.

This issue occurs when the following conditions are true:

•	You open a Microsoft PowerPoint 97 or a Microsoft PowerPoint 2000 presentation in Microsoft Office PowerPoint 2007, in Microsoft Office PowerPoint 2003, or in Microsoft PowerPoint 2002.
•	The presentation has one or more embedded fonts.

Embedded fonts are typically only a subset of the full font set. When you save an existing PowerPoint 97 or PowerPoint 2000 presentation in PowerPoint 2007, in PowerPoint 2003, or in PowerPoint 2002, the full font set is embedded instead of the smaller font subset of the characters.

If the Embed TrueType fonts check box was selected when the PowerPoint 97 or PowerPoint 2000 presentation was saved, PowerPoint automatically embeds a subset of the fonts that are being used. However, this setting is saved with the presentation.

To work around this issue, you must manually select the Embed characters that are used option for each presentation. To do this, follow these steps, as appropriate for the version of PowerPoint that you are running.

PowerPoint 2003 or PowerPoint 2002

1.	Open the PowerPoint 97 or PowerPoint 2000 presentation.
2.	On the Tools menu, click Options.
3.	Click the Save tab.
4.	Under the Embed TrueType fonts check box, click Embed characters that are used only.
5.	Click OK.

Back to the top

PowerPoint 2007

1.	Open the PowerPoint 97 or PowerPoint 2000 presentation.
2.	Click the Microsoft Office Button, and then click PowerPoint Options.
3.	Click Save, and then click to select the Embed fonts in the file check box.
4.	Click Embed only the characters used the presentation.
5.	Click OK.

Now, PowerPoint will embed only those fonts that are used in the presentation when you save the presentation.

To resolve this issue for presentations that are already saved, you must reduce the file size.

If you have already saved the PowerPoint 97 or PowerPoint 2000 presentation in PowerPoint 2007, in PowerPoint 2003, or in PowerPoint 2002, the file size has already increased. To reduce the file size, follow these steps, as appropriate for the version of PowerPoint that you are running.

Back to the top

PowerPoint 2003 or PowerPoint 2002

1.	Open the presentation.
2.	On the Tools menu, click Options.
3.	Click the Save tab.
4.	Under the Embed TrueType fonts check box, click Embed characters that are used only.
5.	Click OK.
6.	Save the presentation.
7.	In Windows Explorer, verify that the file size has decreased.

Back to the top

PowerPoint 2007

1.	Open the presentation.
2.	Click the Microsoft Office Button, and then click PowerPoint Options.
3.	Click Save, and then click to select the Embed fonts in the file check box.
4.	Click Embed only the characters used the presentation.
5.	Click OK.
6.	Save the presentation.
7.	In Windows Explorer, verify that the file size has decreased.

If the file size did not change, try saving the presentation one more time.

If the file size still does not change, you must save a new copy of the presentation. To do this, click Save As on the File menu, and then rename the presentation.

If the file size still does not change, turn off font embedding for that presentation. After you turn off font embedding, save a new copy of the presentation.

Note The fonts will be replaced with the nearest equivalent font that is present on the computer if you do not have the same fonts on the computer.

To determine what fonts are used in the presentation, follow these steps:

1.	Open the original presentation.
2.	On the File menu, click Properties.
3.	Click the Contents tab, and then note the fonts that are listed in the Fonts in use list
4.	Click Start, click Run, type control fonts in the Open box, and then click OK.
5.	Compare the fonts in the Fonts folder to the fonts that you noted in step 3.

In PowerPoint 2002 and in later versions of PowerPoint, you can embed a subset of a font by using the Embed characters in use only option. This option is saved with the presentation. When you save the presentation, PowerPoint 2002, PowerPoint 2003, or PowerPoint 2007 will embed the complete font set into the presentation.
