Embed Fonts in PowerPoint 2010 and 2013
If you need to share presentations using custom fonts then you need to make sure the host computer will have this font installed, otherwise the presentation may not look the same and the fonts will be replaced by the default ones in the host machine.
But PowerPoint lets you choose to embed the fonts in the output .ppt file which may help a lot for sharing purposes. However, you should be aware that embedding fonts in PowerPoint .ppt files may increase the final output size so it is only recommended in case you use fonts extensively in the document. If you just need to use the font for a single title or slide, then it will be better to save the text as an image using the custom font and avoid embedding the custom font in the output file.
If you need to embed Fonts in PowerPoint 2010 and 2013 then when saving the PPT you need to click on Tools submenu (in the Save As dialog). Here go to Save tab and then click on the checkbox Embed fonts in the file.
As you can see, there are other two additional options that may be helpful for performance issues. For example, embed only the characters used in the presentation will optimize the output file and save only those characters that were used in the slide. However, if the person who will receive the presentation will edit it, then it won’t be recommended to save only those characters.
