Fix Incorrect Fonts When Converting PPTX to PDF in Adobe Acrobat
Question details
The user needs to resolve an issue where converting a PPTX file to PDF in Adobe Acrobat takes a long time, uploads the file to the cloud, and results in incorrect or missing fonts.

- Product
- Adobe Acrobat / PowerPoint
- Device & OS
- macOS
- Scenario
- Converting a PowerPoint (PPTX) presentation to a PDF document using Adobe Acrobat on a Mac.
- Observed behavior
- The conversion process uploads the file to Adobe Document Cloud, takes longer than expected, and produces a PDF with substituted or incorrect fonts.
Ensure you have the original PowerPoint (PPTX) file available and verify whether you are currently using Adobe Acrobat Reader or Adobe Acrobat Pro DC. Having the original custom font files installed on your Mac is also recommended.
Use Adobe Acrobat Pro DC Instead of Reader
Using Acrobat Pro DC processes the PDF conversion locally, preventing cloud upload delays and preserving document fonts more accurately.
Adobe Acrobat Reader DC relies on Adobe Document Cloud to convert files, which can cause uploads, delays, and font substitution if the cloud servers lack your specific fonts. Switching to Acrobat Pro DC enables local conversion.
Open Adobe Acrobat on your Mac and look at the application name in the top menu bar to see if it says 'Acrobat Reader' or 'Acrobat Pro DC'.
If you only have the free Reader installed, open the Adobe Creative Cloud desktop application, log in with an active subscription, and install Adobe Acrobat Pro DC.
Open your PPTX file using Acrobat Pro DC. Go to 'File' > 'Create' > 'PDF from File' to create the PDF locally without uploading it to Document Cloud.

Embed Fonts in the Original PowerPoint File
Embedding fonts directly within your PowerPoint presentation ensures that custom typography is preserved during the PDF conversion process.
Fix Embedded Fonts Using Acrobat Preflight
If the PDF is already created but suffers from missing fonts, you can use the Preflight tool in Acrobat Pro to embed them post-conversion.
Convert PPTX to PDF Locally and Accurately with WPS Office
WPS Office provides a built-in, lightning-fast PDF converter that processes files locally on your Mac or PC. It natively supports PPTX files, ensuring that fonts, layouts, and animations are perfectly preserved without needing to upload to the cloud.
- 1. Download and install WPS Office: Install WPS Office for Mac or PC from the official website and launch the application.
- 2. Open the PPTX file: Launch the WPS Presentation module and open your PowerPoint (PPTX) file containing the custom fonts.
- 3. Access the export menu: Click on 'Menu' (or 'File' in the top bar), select 'Export to PDF', and choose your preferred output settings.
- 4. Generate the PDF locally: Click 'Export' to instantly generate a high-quality PDF with all original fonts fully embedded on your local drive.

Frequently Asked Questions
Why does Adobe Acrobat upload my PPTX to Document Cloud when creating a PDF?
If you are using the free Adobe Acrobat Reader, the software lacks local PDF creation capabilities and relies on Adobe Document Cloud to process file conversions. Upgrading to Adobe Acrobat Pro DC allows you to convert files locally on your computer.
How do I know if the fonts are successfully embedded in my PDF?
Open your PDF file in Adobe Acrobat, navigate to 'File' > 'Properties', and select the 'Fonts' tab. Every font listed there should have '(Embedded)' or '(Embedded Subset)' displayed next to its name. If not, the font is missing.
Can I embed Mac fonts in a PowerPoint presentation before converting?
Yes, modern versions of Microsoft PowerPoint for Mac allow font embedding. Go to PowerPoint Preferences > Save, and check 'Embed fonts in the file' to ensure custom typography is packaged with the document before PDF conversion.
What happens if I convert a PPTX to PDF without embedding fonts?
If fonts are not embedded and the conversion server or viewer's device does not have the original fonts installed, the system will substitute them with default system fonts. This can drastically alter the layout, text size, and overall appearance of your presentation.
