Limitations

In some cases, Presentation Font Embedder will not be able to embed the fonts that you use in your presentations:

General limitations

Password protected files

When you save your presentation as a password protected file, PowerPoint creates a file in a format which is different than that of a password-free presentation. This different file format is unreadable to Presentation Font Embedder and the app could not open and embed fonts into it.

If you are interested in this functionality, please use our feature request form to let us know about it.

Pre-2007 files

Beginning with the 2007 version, Microsoft introduced new file formats for the Office suite products and set those new formats as the default for saving files. Presentation Font Embedder supports these new file formats (e.g. files ending with a ‘pptx’ extension) and does not support any files created by prior versions (e.g. ‘ppt’ extension, usually referred to as PowerPoint 97-2004 format). See Supported File Types for more information.

If you would like to to embed fonts into a PowerPoint 97-2004 file, you can easily convert it to the new format with a recent Office product (including the Mac® versions). Simply open the 97-2004 format file and perform a Save as in the new format. The newly saved file can be embedded using Presentation Font Embedder.

Editable method limitations

Font formats

Computer fonts come in various file formats and not all are suitable for embedding. Only fonts created in TrueType or OpenType-TrueType formats are supported by PowerPoint using the Editable method, and therefore only they can be embedded into presentations. Usually most of the fonts on your computer are of these types. Since PowerPoint does not support viewing embedded fonts of PostScript, bitmap, and other formats, they cannot be embedded.

This limitation also exists when using the built-in font embedding feature of PowerPoint for Windows.

Embedding permissions

Font foundries have the ability to set restrictions for embedding in the files of fonts that they design. They may decide to allow embedding of their font, restrict edibility of embedded font, or restrict embedding altogether, among other preferences.
Presentation Font Embedder checks the embedding permissions of each font that it is about to embed. When it encounters a font that is restricted for embedding by the designer, this font is skipped and a warning about this is shown in the results panel.
This limitation also exists on the Windows version of PowerPoint.

Embedded fonts display

PowerPoint versions other than for Windows and Android lack the ability to interact with fonts files embedded in presentations using the Editable method. The Mac PowerPoint for example, will not display fonts embedded in presentations if they were embedded with Presentation Font Embedder, or even if they were embedded with PowerPoint on Windows.

Some fonts may not embed even if they have embedding permissions and exist in a supported format, due to per-font characteristics.

Universal method limitations

Required software

This method requires an active installation of Microsoft PowerPoint 2011, 2016, or 365.

Animations

Due to the nature of this method, which is to render the text shapes into images, some animations cannot be maintained after the embedding process. This includes animations of individual text paragraphs and characters within shapes, and animations of color change.

Slide masters and slide layouts

At this time, the Universal method is unable to embed shapes of slide masters and slide layouts. We hope to bring support for these shapes in the future.
