In this how-to article, we provide the complete process to extract images from PDF using C#, how to configure the required library for extracting images, and a sample code to demonstrate the implementation of the C# extract images from PDF application. These instructions do not depend on any additional software and can be used on any operating system like MS Windows, Linux, and macOS that support a .NET environment.

Steps to Extract Images from PDF using C#

1. Setup GroupDocs.Parser for .NET package from the NuGet package manager in the .NET project to extract images from PDF document
2. Add a reference of the necessary namespaces for extracting the images from PDF
3. Create an object of the Parser class for loading the input PDF document
4. Call the GetImages method and get a collection of image objects
5. Finally, iterate over the collection and get sizes, image types, and image contents

The above stepwise instructions can be easily followed for the development of the extract image from PDF C# application in the .NET projects. The Parser class allows loading the source PDF file for extracting images after configuring the required package and importing the essential namespaces. Then, the GetImages method of the Parser class enables you for getting the image objects collection and parse it for extracting the image size, type, and contents.

Code to Extract Images from PDF using C#

In the preceding snippet, the get image from PDF C# capability is developed using the instructions explained in the previous section. As you can see, it’s just a matter of a couple of API calls for extracting the images from a PDF file. Moreover, this sample code can be adapted for extracting images from various other document formats including DOC, DOCX, XLSX, XLT, HTML, PPT, PPTX, EPUB, and many more.

We have discussed the step-by-step process to extract images from PDF in C# and developed a sample code for it in this post. Recently, we published an article for extracting text from PDF using C#, have a look at how to Extract Text from PDF in C# guide for more information.
