Cloud fonts are available to Office 365 subscribers on all platforms and devices. If you have Office 365, you’ll see them in your font list indicated by a cloud and arrow icon. When you apply one of these fonts PowerPoint downloads it in the background and applies it to your text. When someone views the file with Office 365 or Office 2019, PowerPoint downloads missing fonts from the font service and the file renders the same as it was authored, without embedding.
