FreeOffice: Embedding fonts is not included in SoftMaker FreeOffice.
You can use the Fonts tab in the dialog box of the ribbon command File | Properties 
to embed the fonts that you used in a document into the document file.
Note: This feature is available only on Windows. This includes embedding fonts as well as displaying fonts that were embedded in a file.
Embedding fonts into a document file is useful when you are sharing a presentation with others. If you want to make sure that the fonts used in your presentation look exactly the same on your computer and on other devices, it's a good idea to embed all fonts in the file.
If a file with embedded fonts is opened on another computer, Presentations will install all embedded fonts temporarily. After you exit Presentations, they are automatically removed.
To embed fonts into a presentation, proceed as follows:
| 1. | Create or open the desired presentation. |
| 2. | Choose the command File | Properties and switch to the Fonts tab. |
| 3. | The dialog box presents a list of all fonts that were used in the document. A checkbox is displayed in front of each font. Click to place a check mark in front of all fonts that you want to embed in the document. |
| Tip: You can use the Select all and Deselect all buttons to select or deselect all embeddable fonts at once. |
| 4. | Confirm with OK. |
| 5. | Save the file. |
The selected fonts are now embedded into the document file.
Notes
▪Embedding fonts works with Microsoft PowerPoint documents in addition to Presentations documents.
▪Some fonts generally do not allow users to embed them into documents. For such fonts, the checkbox for embedding is unavailable.
▪Many commercial fonts allow embedding, but not editing documents in these fonts. When you embed such fonts, a message will appear when the document is opened on a different computer. The user can then decide whether he wants to edit the document, print it or just view the slide show. If he chooses "Edit", the embedded fonts will not be available.
▪When sharing documents (for example, by e-mail), keep in mind that embedding fonts can significantly increase file size, especially when using fonts with large character sets (for example, Asian fonts).
▪System fonts like Arial, Courier New, Times New Roman or Symbol cannot be embedded. These fonts are available on every Windows system anyway.
