Check whether fonts in PowerPoint presentation are available in machine for PDF or image conversion

4 mins read

If the necessary fonts used in a PowerPoint presentation are not installed on the production machine, the Presentation library will use an alternate font for rendering the text. As a result, you may notice differences in the rendered text in the generated PDF or image files during the PPTX to PDF/image conversion process.

We strongly recommend you to install all the fonts used in the PowerPoint presentation on the production machine to achieve proper preservation in the generated PDF/image file.

You can check whether the necessary fonts are available on the machine by following approach.

Using Presentation font substitution Utility:


Syncfusion .NET PowerPoint library has a font substitution event handler to set alternate fonts for missing fonts in the PowerPoint presentation during PPTX to PDF/image conversion. Using this event handler, you can print the fonts used in your input presentation that are not available on the production machine. Then, you can install the necessary missing fonts.

You can find the utility on GitHub and run it.
Kindly replace the existing input Word document with the required Word document in the “Data” folder before running the sample.
