Extract Images from a PowerPoint Document in Python

To extract images from an entire PowerPoint presentation, you need to use the Presentation.Images property to get the collection of all the images in the presentation, then iterate through the elements in the collection and call IImageData.Image.Save() method to save each element to an image file. The following are the detailed steps:

• Create a Presentation instance.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get the collection of all the images in the document using Presentation.Images property.
• Iterate through the elements in the collection, and save each element as an image file using the IImageData.Image.Save() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation instance
ppt = Presentation()

# Load a PowerPoint document
ppt.LoadFromFile("sample.pptx")

# Iterate through all images in the document
for i, image in enumerate(ppt.Images):

    # Extract the images
    ImageName = "ExtractImage/Images_"+str(i)+".png"
    image.Image.Save(ImageName)

ppt.Dispose()

Extract Images from a Presentation Slide in Python

To extract images from a specific slide, you need to iterate through all shapes on the slide and find the shapes that are of SlidePicture or PictureShape type, then use the SlidePicture.PictureFill.Picture.EmbedImage.Image.Save() or PictureShape.EmbedImage.Image.Save() method to save the images to image files. The following are the detailed steps:

• Create a Presentation instance.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get a specified slide using Presentation.Slides[int] property.
• Iterate through all shapes on the slide.
• Determine whether the shapes are of SlidePicture or PictureShape type. If so, save the images to image files using SlidePicture.PictureFill.Picture.EmbedImage.Image.Save() or PictureShape.EmbedImage.Image.Save() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation instance
ppt = Presentation()

# Load a PowerPoint document
ppt.LoadFromFile("sample.pptx")

# Get a specified slide
slide = ppt.Slides[2];

i = 0
#Traverse all shapes in the slide
for s in slide.Shapes:

    # Determine if the shape is of SlidePicture type
    if isinstance(s, SlidePicture):

        # If yes, then extract the image
        ps = s if isinstance(s, SlidePicture) else None
        ps.PictureFill.Picture.EmbedImage.Image.Save("Output/SlidePic_"+str(i)+".png")
        i += 1

    # Determine if the shape is of PictureShape type
    if isinstance(s, PictureShape):

        # If yes, then extract the image
        ps = s if isinstance(s, PictureShape) else None
        ps.EmbedImage.Image.Save("Output/SlidePic_"+str(i)+".png")
        i += 1

ppt.Dispose()

Why Convert PowerPoint to PDF?

Converting PowerPoint files to PDF offers several advantages:

• Universal Compatibility: PDF files can be opened on virtually any device or operating system without needing PowerPoint installed.
• Preserved Formatting: Unlike PowerPoint files, PDFs lock in layout, fonts, and images to avoid rendering inconsistencies.
• Enhanced Security: PDF files can be encrypted, making them ideal for sharing confidential information.
• Reduced File Size: PDFs often have a smaller file size than PowerPoint presentations, making them easier to share via email or upload online.

Convert PowerPoint to PDF with Default Settings

Spire.Presentation makes it easy to convert PowerPoint files to PDF with just a few lines of code.

The example below shows how to load a .pptx or .ppt file and export it to PDF using default settings - ideal for quick conversions where no customization is needed.

from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load a PPTX file
presentation.LoadFromFile("Input.pptx")
# Or load a PPT file
# presentation.LoadFromFile("Input.ppt")

# Save the file as a PDF
presentation.SaveToFile("Basic_conversion.pdf", FileFormat.PDF)
presentation.Dispose()

Export PowerPoint to PDF with Advanced Settings

Spire.Presentation provides a range of advanced settings that give you control over how the PDF output is generated, making it ideal for both professional use and archival purposes. For example, you can:

• Export a Particular Slide to PDF
• Adjust Slide Size for Optimal PDF Output
• Include Hidden Slides in the Converted PDF
• Generate PDF/A-compliant Files from PowerPoint

Export a Particular Slide to PDF

If you only need to share a specific part of your presentation, Spire.Presentation allows you to extract and convert individual slides to a PDF. This is especially useful for generating slide-specific reports or handouts.

from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load the PowerPoint file
presentation.LoadFromFile("Input.pptx")

# Get the desired slide (e.g., the second slide)
slide = presentation.Slides.get_Item(1)

# Save the slide as a PDF
slide.SaveToFile("Single_slide.pdf", FileFormat.PDF)
presentation.Dispose()

Adjust Slide Size for Optimal PDF Output

To ensure that your PDF meets printing or layout requirements, you can adjust the slide dimensions before conversion. Spire.Presentation lets you set standard slide sizes as well as custom slide dimensions so the output aligns with your document formatting needs.

from spire.presentation import *

# Create a Presentation object
presentation = Presentation()
# Load the PowerPoint file
presentation.LoadFromFile("Input.pptx")

# Set the slide size to a standard slide size like A4
presentation.SlideSize.Type = SlideSizeType.A4

# # Or you can set custom slide size (e.g., 720x540 points)
# presentation.SlideSize.Size = SizeF(720.0, 540.0)

# Fit content to the new slide size
presentation.SlideSizeAutoFit = True

# Save the presentation as a PDF
presentation.SaveToFile("Resized_output.pdf", FileFormat.PDF)
presentation.Dispose()

Include Hidden Slides in the Converted PDF

By default, hidden slides are excluded from conversion. However, if your workflow requires complete documentation, Spire.Presentation enables you to include hidden slides in the output PDF.

from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load the PowerPoint file
presentation.LoadFromFile("Input.pptx")

# Get the SaveToPdfOption object
option = presentation.SaveToPdfOption

# Enable ContainHiddenSlides option
option.ContainHiddenSlides = True

# Save the presentation as a PDF
presentation.SaveToFile("Include_hidden_slides.pdf", FileFormat.PDF)
presentation.Dispose()

Generate PDF/A-compliant Files from PowerPoint

PDF/A is a specialized format intended for long-term digital preservation. If your organization needs to archive presentations in a standards-compliant format, Spire.Presentation allows you to export PDF/A files that conform to archival best practices.

from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load the PowerPoint file
presentation.LoadFromFile("Input.pptx")

# Get the SaveToPdfOption object
option = presentation.SaveToPdfOption

# Set PDF compliance to PDF/A-1a
option.PdfConformanceLevel = PdfConformanceLevel.Pdf_A1A

# Save the presentation as a PDF
presentation.SaveToFile("Pdf_a_output.pdf", FileFormat.PDF)
presentation.Dispose()
