SlideShare supports a lot of fonts and we are constantly adding more. However, if you are using uncommon fonts in your presentation, it is possible they may not convert perfectly.

Here are some ways to solve this issue:

• Try to refresh the page as sometimes the fonts do not load properly in the new HTML player
• If refreshing does not work, try to open the content in another browser
• Convert the documents/presentations to PDF and upload again
• Try embedding the font inside your ppt, pptx, odp or keynote file and upload again
• Try using some of the common fonts and upload again
