Can Multiple Fonts Be Inserted into a Presentation Simultaneously?

I am currently using ‘/slides/fonts/embedded’ to embed fonts into my PowerPoint presentation. May I ask if there is an interface that allows me to embed multiple fonts into my PowerPoint presentation simultaneously?

Yes – Aspose.Slides can embed multiple fonts in a single presentation

Aspose.Slides does not limit you to a single font file.
You can embed any number of fonts that are required by the slides (or even embed all fonts that the presentation references) before saving the file.

How to embed several fonts

Platform Key API What it does
.NET presentation.Fonts.EmbeddingMode = FontEmbeddingMode.EmbedAllFonts; Embeds every font that the presentation uses.
.NET presentation.Fonts.EmbedFont(string fontPath); (repeat for each font) Embeds specific fonts one‑by‑one.
Java presentation.getFonts().setEmbeddingMode(FontEmbeddingMode.EMBED_ALL_FONTS); Same as the .NET EmbedAllFonts option.
Java presentation.getFonts().embedFont(String fontPath); Embed a particular font file; call it for each font you need.
All languages LoadOptions with setFontFolder(String folderPath) Makes a whole folder of fonts available; you can then embed any of those fonts using the methods above.

Example – .NET (C#)

using Aspose.Slides;
using Aspose.Slides.Export;

// 1️⃣ Load the presentation
using (Presentation pres = new Presentation("input.pptx"))
{
    // 2️⃣ Make a folder with all fonts you want to embed
    // (e.g., MyFonts\Arial.ttf, MyFonts\Calibri.ttf, MyFonts\MyCustomFont.otf)
    string fontsFolder = @"C:\MyFonts";

    // 3️⃣ Tell Aspose.Slides where to find the fonts
    LoadOptions loadOptions = new LoadOptions();
    loadOptions.FontsFolder = fontsFolder;
    loadOptions.FontsFolderIsSystem = false;   // use only the supplied folder
    pres.Load(loadOptions);

    // 4️⃣ Embed **all** fonts that the presentation references
    pres.Fonts.EmbeddingMode = FontEmbeddingMode.EmbedAllFonts;

    //   –‑or‑– embed specific fonts only:
    // pres.Fonts.EmbedFont(Path.Combine(fontsFolder, "Arial.ttf"));
    // pres.Fonts.EmbedFont(Path.Combine(fontsFolder, "MyCustomFont.otf"));

    // 5️⃣ Save the result
    pres.Save("output.pptx", SaveFormat.Pptx);
}

Example – Java

import com.aspose.slides.*;

public class EmbedMultipleFonts {
    public static void main(String[] args) throws Exception {
        // Load presentation
        Presentation pres = new Presentation("input.pptx");

        // Folder that contains the fonts you want to embed
        String fontsFolder = "C:/MyFonts";

        // Make the folder visible to the loader
        LoadOptions loadOptions = new LoadOptions();
        loadOptions.setFontsFolder(fontsFolder);
        loadOptions.setFontsFolderIsSystem(false);
        pres.load(loadOptions);

        // Embed every font used in the presentation
        pres.getFonts().setEmbeddingMode(FontEmbeddingMode.EMBED_ALL_FONTS);

        // –‑or‑– embed particular fonts:
        // pres.getFonts().embedFont(fontsFolder + "/Arial.ttf");
        // pres.getFonts().embedFont(fontsFolder + "/MyCustomFont.otf");

        // Save the file
        pres.save("output.pptx", SaveFormat.Pptx);
    }
}

What the code does

  1. Load the presentation – you can optionally provide a LoadOptions object that points to a folder containing all the font files you plan to embed.
  2. Make the fonts available – Aspose.Slides scans the folder and registers the fonts.
  3. Choose the embedding strategy
    • EmbedAllFonts → automatically embeds every font that appears in the slides.
    • EmbedFont(path) → embed a specific font file; call this method for each font you need.
  4. Save – the resulting file contains the embedded font data, and anyone opening it will see the intended typography even if those fonts are not installed on their machine.

Tips & best practices

  • Use a dedicated font folder – This avoids accidental inclusion of unwanted system fonts.
  • Check the font usage – If you only need a subset of fonts, embedding them individually keeps the file size smaller.
  • Supported formats – TrueType (.ttf) and OpenType (.otf) fonts are fully supported for embedding.
  • Validation – After saving, you can call presentation.Fonts.IsEmbedded() (or the equivalent in Java) to confirm that the desired fonts are embedded.

Can you provide me with an example of Node.js based on your above answer?
