### Step 3: Converting PDF to Images

Let's have look into the code to convert a [PDF into images](https://ironpdf.com/examples/rasterize-a-pdf-to-images/) using IronPDF. Here i'm going to use a 10 page PDF document and rasterize it to images with simply one line of code.

#### Code Snippet:

The following code snippet convert PDF to JPG and PNG images:

```csharp
using IronPdf;
using IronSoftware.Drawing; // Required for AnyBitmap class

class Program
{
    static void Main(string[] args)
    {
        // Load the PDF file you want to convert to images
        PdfDocument pdf = PdfDocument.FromFile("Example.pdf");

        // Extract all the pages to a folder as image files (PNG by default)
        pdf.RasterizeToImageFiles(@"C:\image\folder\*.png");

        // Specify dimensions and PDF page ranges (optional)
        pdf.RasterizeToImageFiles(@"C:\image\folder\example_pdf_image_*.jpg", 100, 80);

        // Extract all pages as AnyBitmap objects
        AnyBitmap[] pdfBitmaps = pdf.ToBitmap();

        Console.WriteLine("PDF converted to images successfully!");
    }
}
```

#### Explanation:

1. **Loading the PDF**: We use `PdfDocument.FromFile` to load the existing PDF, `Example.pdf`, into the `pdf` variable.

2. **Converting to Image Files**: IronPDF's `RasterizeToImageFiles` method is used to convert the PDF pages into image files. By default, it saves images as PNG files, but you can specify other formats such as JPEG or TIFF.

3. **Specifying Dimensions and Page Ranges (Optional)**: You can also specify image dimensions (width and height in pixels) and page ranges for conversion. In the second `RasterizeToImageFiles` method call, we save images as JPEG files with a width of 100 pixels and a height of 80 pixels.

4. **Extracting as AnyBitmap Objects**: The `ToBitmap` method extracts all pages from the PDF as `AnyBitmap` objects. This gives you flexibility to further process the images as needed.

### Step 4: Running the Application

Build and run the application. If everything is set up correctly, you should see the message "PDF converted to images successfully!" in the console output. Here are the extracted images in png and jpg format:
