PowerPoint presentations (PPTX, PPT) often contain valuable graphics, logos, and photos that you may need to reuse in reports or other projects. Instead of manually saving each image, we can programmatically extract images from PowerPoint slides.

Why Extract Images from PowerPoint?

Extracting images from PowerPoint presentations is useful when you want to:

  • Retrieve photos, icons, and diagrams used in slides.
  • Build digital asset libraries from marketing presentations.
  • Reuse visual elements without manually saving each image.
  • Automate bulk image extraction from multiple presentations.

PowerPoint Image Extraction API

GroupDocs.Parser Cloud SDK for .NET is an award winning API for parsing and analyzing document contents. Among a plethora of file formats it supports including (PDF, Excel, DOCX etc.), it is also a powerful solution for manipulating PowerPoint presentations.

Prerequisites

Before proceeding, ensure you have:

  • An account over GroupDocs Cloud to obtain Client ID and Client Secret details.
  • .NET 6.0 or later installed on your system.
  • Visual Studio or another compatible IDE.

Install PDF parser API

You can easily install the SDK from NuGet using the command below:

NuGet\Install-Package GroupDocs.Parser-Cloud -Version 25.7.0

Extract PPT Images using C# .NET

Please follow these steps to extract all images from a PowerPoint presentation programmatically.

Step 1: Initialize the API.

var configuration = new Configuration("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");
var parserApi = new ParserApi(configuration);

Step 2: Set File and Options.

var fileInfo = new FileInfo { FilePath = "presentation.ppt" };
var options = new ImagesOptions{ FileInfo = fileInfo };
var request = new ImagesRequest(options);

Step 3: Extract Images.

var response = parserApi.Images(request);
foreach (var image in response.Images)
{
    Console.WriteLine($"Images Path: {image.Path}");
}
  • 💡 You can modify the request to extract images only from selected slides by defining the slide numbers in the options parameter.

Convert PowerPoint to JPEG using cURL

Other than the approach to programmatically extract PowerPoint images, you may consider using cURL commands with the REST API without writing code.

Step 1 – Get Access Token:

curl -X POST "https://api.groupdocs.cloud/connect/token" \
-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
-H "Content-Type: application/x-www-form-urlencoded"

Step 2 – Download Images from PowerPoint

curl -v -X POST "https://api.groupdocs.cloud/v1.0/parser/images" \
-H  "accept: application/json" \
-H  "authorization: Bearer {ACCESS_TOKEN}" \
-H  "Content-Type: application/json" \
-d "{  \"FileInfo\": {    \"FilePath\": \"slides.pptx\",    \"StorageName\": \"internal\"  },  \"OutputPath\": \"internal\"}"
  • Replace {ACCESS_TOKEN} with the token obtained above, and specify your PowerPoint filename under FilePath.
