Convert PowerPoint to PDF

Using Aspose.Slides, you can convert presentations in these formats to PDF:

  • PPT
  • PPTX
  • ODP

To convert a presentation to PDF, you simply have to pass the file name as an argument in the Presentation class and then save the presentation as a PDF using a Save method. The Presentation class exposes the Save method that is typically used to convert a presentation to PDF.

Aspose.Slides allows you to convert:

  • an entire presentation to PDF
  • specific slides in a presentation to PDF
  • a presentation

Aspose.Slides exports presentations to PDF in a way that makes the contents of the resulting PDFs very similar to those in the original presentations. These known elements and attributes are often rendered properly in presentation to PDF conversions:

  • images
  • text boxes and other shapes
  • texts and their formatting
  • paragraphs and their formatting
  • hyperlinks
  • headers and footers
  • bullets
  • tables

Convert PowerPoint to PDF

The standard PowerPoint PDF conversion operation is executed using default options. In this case, Aspose.Slides tries to convert the provided presentation to PDF using optimal settings at the maximum quality levels.

This Java code shows you how to convert a PowerPoint to PDF:

// Instantiates a Presentation class that represents a PowerPoint file
Presentation pres = new Presentation("PowerPoint.ppt");
try {
    // Saves the presentation as a PDF
    pres.save("PPT-to-PDF.pdf", SaveFormat.Pdf);
} finally {
    if (pres != null) pres.dispose();
}

Convert PowerPoint to PDF with Options

Aspose.Slides provides custom options—properties under the PdfOptions class—that allow you to customize the PDF (resulting from the conversion process), lock the PDF with a password, or even specify how the conversion process should go.

Convert PowerPoint to PDF with Custom Options

Using custom conversion options, you can set your preferred quality setting for JPG images, specify how metafiles should be handled, set a compression level for texts, etc.

This Java code demonstrates an operation in which a PowerPoint is converted to PDF with several custom options:

// Instantiates a Presentation class that represents a PowerPoint file
Presentation pres = new Presentation("PowerPoint.pptx");
try {
    // Instantiates the PdfOptions class
    PdfOptions pdfOptions = new PdfOptions();
    
    // Sets the Jpeg quality
    pdfOptions.setJpegQuality((byte)90);
    
    // Sets the behavior for metafiles
    pdfOptions.setSaveMetafilesAsPng(true);
    
    // Sets the text compression level
    pdfOptions.setTextCompression(PdfTextCompression.Flate);
    
    // Defines the PDF standard
    pdfOptions.setCompliance(PdfCompliance.Pdf15);
    
    // Saves the presentation as a PDF
    pres.save("PowerPoint-to-PDF.pdf", SaveFormat.Pdf, pdfOptions);
} finally {
    if (pres != null) pres.dispose();
}

Convert PowerPoint to PDF with Hidden Slides

If a presentation contains hidden slides, you can use a custom option—the ShowHiddenSlides property from the PdfOptions class—to instruct Aspose.Slides to include the hidden slides as pages in the resulting PDF.

This Java code shows you how to convert a PowerPoint presentation to PDF with hidden slides included:

// Instantiates a Presentation class that represents a PowerPoint file
Presentation pres = new Presentation("PowerPoint.pptx");
try {
    // Instantiates the PdfOptions class
    PdfOptions pdfOptions = new PdfOptions();
    
    // Adds hidden slides
    pdfOptions.setShowHiddenSlides(true);
    
    // Saves the presentation as a PDF
    pres.save("PowerPoint-to-PDF.pdf", SaveFormat.Pdf, pdfOptions);
} finally {
    if (pres != null) pres.dispose();
}

Convert PowerPoint to Password Protected PDF

This Java code shows you how to convert a PowerPoint to a password-protected PDF (using protection parameters from the PdfOptions class):

// Instantiates a Presentation object that represents a PowerPoint file
Presentation pres = new Presentation("PowerPoint.pptx");
try {
    /// Instantiates the PdfOptions class
    PdfOptions pdfOptions = new PdfOptions();
    
    // Sets PDF password and access permissions
    pdfOptions.setPassword("password");
    pdfOptions.setAccessPermissions(PdfAccessPermissions.PrintDocument | PdfAccessPermissions.HighQualityPrint);
    
    // Saves the presentation as a PDF
    pres.save("PPTX-to-PDF.pdf", SaveFormat.Pdf, pdfOptions);
} finally {
    if (pres != null) pres.dispose();
}

Convert Selected Slides in PowerPoint to PDF

This Java code shows you how to convert specific slides in a PowerPoint presentation to PDF:

// Instantiates a Presentation object that represents a PowerPoint file
Presentation pres = new Presentation("PowerPoint.pptx");
try {
    // Sets an array of slides positions
    int[] slides = { 1, 3 };
    
    // Saves the presentation as a PDF
    pres.save("PPTX-to-PDF.pdf", slides, SaveFormat.Pdf);
} finally {
    if (pres != null) pres.dispose();
}

Convert PowerPoint to PDF with Custom Slide Size

This Java code shows you how to convert a PowerPoint when its slide size is specified to a PDF:

// Instantiates a Presentation object that represents a PowerPoint file 
Presentation pres = new Presentation("SelectedSlides.pptx");
try {
    Presentation outPres = new Presentation();
    try {
        ISlide slide = pres.getSlides().get_Item(0);

        outPres.getSlides().insertClone(0, slide);
        
        // Sets the slide type and size 
        outPres.getSlideSize().setSize(612F, 792F, SlideSizeScaleType.EnsureFit);
        
        PdfOptions pdfOptions = new PdfOptions();
        INotesCommentsLayoutingOptions options = pdfOptions.getNotesCommentsLayouting();
        options.setNotesPosition(NotesPositions.BottomFull);

        outPres.save("PDFnotes_out.pdf", SaveFormat.Pdf, pdfOptions);
    } finally {
        if (pres != null) pres.dispose();
    }
} finally {
    if (pres != null) pres.dispose();
}

Convert PowerPoint to PDF in Notes Slide View

This Java code shows you how to convert a PowerPoint to PDF notes:

// Instantiates a Presentation class that represents a PowerPoint file
Presentation pres = new Presentation("SelectedSlides.pptx");
try {
    PdfOptions pdfOptions = new PdfOptions();
    INotesCommentsLayoutingOptions options = pdfOptions.getNotesCommentsLayouting();
    options.setNotesPosition(NotesPositions.BottomFull);

    pres.save("Pdf_With_Notes.pdf", SaveFormat.Pdf, pdfOptions);
} finally {
    if (pres != null) pres.dispose();
}

Accessibility and Compliance Standards for PDF

Aspose.Slides allows you to use a conversion procedure that complies with Web Content Accessibility Guidelines (WCAG). You can export a PowerPoint document to PDF using any of these compliance standards: PDF/A1a, PDF/A1b, and PDF/UA.

This Java code demonstrates a PowerPoint to PDF conversion operation in which multiple PDFs based on different compliance standards are obtained:

Presentation pres = new Presentation("pres.pptx");
try {
    PdfOptions pdfOptions = new PdfOptions();
    
    pdfOptions.setCompliance(PdfCompliance.PdfA1a);
    pres.save("pres-a1a-compliance.pdf", SaveFormat.Pdf, pdfOptions);

    pdfOptions.setCompliance(PdfCompliance.PdfA1b);
    pres.save("pres-a1b-compliance.pdf", SaveFormat.Pdf, pdfOptions);

    pdfOptions.setCompliance(PdfCompliance.PdfUa);
    pres.save("pres-ua-compliance.pdf", SaveFormat.Pdf, pdfOptions);
} finally {
    if (pres != null) pres.dispose();
}
