MAPICan Embedded Fonts Make a PowerPoint File Larger?
Font embedding improves portability by packaging supported font data with the presentation, but that additional data has to be stored somewhere — inside the file.
Yes. Microsoft states that embedded fonts increase PowerPoint file size. Some fonts are much larger than others, and Microsoft recommends embedding only the characters used in the presentation when reducing file size matters.
yes
The answer
Yes. Embedded fonts can make a PowerPoint file larger.
Why
Microsoft says embedded fonts increase presentation size because font information is stored in the file. It recommends embedding only the characters used in the presentation when possible, and notes that some fonts are much larger than others.
When it is usually OK
- The presentation embeds one or more custom fonts
- The embedded font contains a large character set
- Several large fonts are embedded
- The file becomes larger after font embedding is enabled
When you should not
- The presentation uses system fonts without embedding
- The font is referenced but not packaged inside the presentation
Risks and exceptions
- Large embedded fonts can make sharing and upload slower
- Removing font embedding can cause substitution on systems that lack the font
- Some fonts cannot be embedded because of licensing permissions
Best practice
Embed fonts only when portability requires it, and use Microsoft's option to embed only the characters used when that option meets your sharing needs.
Alternatives
- Use common fonts already installed on target systems
- Embed only used characters
- Choose a smaller or more portable font when file size is critical
