Extracting images from PDF documents is a common requirement when dealing with reports, scanned documents, or presentation files that contain embedded visuals. Instead of manually saving each image, you can automate the extraction process with GroupDocs.Parser Cloud SDK for .NET.

In this tutorial, you’ll learn how to extract images from PDF files using C# .NET and the GroupDocs.Parser Cloud REST API, along with easy-to-follow code snippets for quick integration.

Why Extract Images from PDF Files?

There are many practical use cases for automating PDF image extraction:

  • Retrieve logos, charts, and infographics from marketing or financial reports.
  • Extract photos and scans from multi-page PDFs.
  • Build automated content extraction pipelines for document analysis.
  • Process large batches of PDFs without manual effort or desktop tools.

PDF Parsing API

GroupDocs.Parser Cloud SDK for .NET is a lightweight and easy-to-integrate API wrapper allowing you to extract structured content—such as text, images and other components of the PDF as well as other file formats including Word, Excel, etc.

Prerequisites

Before getting started, ensure you have:

  • A GroupDocs Cloud Account to get your Client ID and Client Secret.
  • .NET 6.0 or later installed on your system.
  • Visual Studio or your preferred 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 Images from PDF using C# .NET

Follow these simple steps to extract all images from a PDF file programmatically.

Step 1: Set up Configuration.

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

Step 2: Specify File Information.

var fileInfo = new FileInfo
{
    FilePath = "sample.pdf"
};

var options = new ImagesOptions
{
    FileInfo = fileInfo
};

var request = new ImagesRequest(options);

Step 3: Extract Images from PDF.

var response = parserApi.Images(request);

foreach (var image in response.Images)
{
    Console.WriteLine($"Image Path: {image.Path}");
}

Download PDF Images via cURL

Alternatively, you can also extract images using GroupDocs.Parser REST API and cURL commands.

Step 1 – Generate 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 – Extract Images via REST API:

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\": \"Binder1.pdf\",    \"StorageName\": \"internal\"  },  \"OutputPath\": \"internal\",  \"StartPageNumber\": 1,  \"CountPagesToExtract\": 2}"
  • Replace <ACCESS_TOKEN> with the one you generated.
