MS PowerPoint: Transparency Fonts Not Exporting Correctly in PDFs (MacOS/Office365)

Introduction

In recent times, users have reported issues with PowerPoint fonts not exporting correctly when saving presentations as PDFs on MacOS and Office 365. This article will discuss the key concepts of this problem and potential solutions.

Understanding the Issue

When exporting PowerPoint slides to PDF format, some transparency fonts may not render correctly. This can lead to text appearing as boxes or being replaced with default fonts. The problem is not exclusive to MacOS or Office 365 but can occur on other platforms as well.

Identifying Transparency Fonts

Transparency fonts are those that support the Alpha Channel property, which enables them to have transparent backgrounds. Common examples include ClearType Font Collection for Windows and Charter, DejaVu Serif, and Liberation Sans for Linux. To check if a font is transparency-enabled, follow these steps:

1. Open your PowerPoint presentation.
2. Go to the "Home" tab, and click on "Fonts" in the "Fonts" group.
3. Select the font in question and right-click on it.
4. Choose "Font Outline" from the context menu.

If the font's characters appear with solid outlines, it is not a transparency font. However, if the characters are displayed as wireframes, it is a transparency font.

Potential Solutions

Option 1: Save as Image

One solution is to save your slides as images instead of PDFs. This will ensure that all fonts and transparency effects are preserved. To save as an image:

1. Select the slide(s) you want to save.
2. Go to the "File" tab and choose "Save As."
3. In the "Save As" dialog box, select the image format you prefer (e.g., PNG or JPG).

Option 2: Embed Fonts

Another approach is to embed the fonts in your PowerPoint presentation before exporting it to PDF. This can help ensure that the fonts are available when the PDF is opened. To embed fonts:

1. Open your PowerPoint presentation.
2. Go to the "File" tab and choose "Info."
3. Click on "Properties" and then "Advanced Properties."
4. Under "Custom XML Data," click on the "Edit XML Data" button.
5. Paste the following code snippet:

Replace "fontTable.xml" with the name of your font file (e.g., "ClearType.xml" for ClearType Font Collection). Save the presentation and try exporting it to PDF again.
