Convert a PDF to Images

Rasterizing a PDF to Images

Rasterizing a PDF to an image involves converting each page of the PDF document into a static image format, such as JPEG or PNG. This process is commonly used when you need to extract individual pages or images from a PDF for various purposes, like displaying them on a website or incorporating them into a different document.

PDF documents can be rasterized into images using IronPDF's PDF to Image Converter. You also have the option to specify the image type for the output images. Each output image will be named with "_pageNumber" at the end to indicate its corresponding page number in the original PDF.

Below is an example of how you can use IronPDF to convert a PDF to images using C#:

// This example demonstrates how to rasterize a PDF into individual images using IronPDF.
using IronPdf;

class PdfToImageExample
{
    static void Main()
    {
        // Define the path to the PDF file you want to rasterize
        string pdfPath = "example.pdf";

        // Create a new instance of IronPdf.PdfDocument from a PDF file
        PdfDocument pdfDoc = PdfDocument.FromFile(pdfPath);

        // Optional: Specify the image format (e.g., JPEG, PNG) and DPI (dots per inch) for output images
        var options = new ImageSaveOptions
        {
            ImageFormat = ImageFormat.Png, // Specify the desired image format
            Dpi = 300 // Specify the resolution of the output images
        };

        // Define the directory where the images will be saved
        string outputDirectory = "OutputImages";

        // Convert each page of the PDF to an image and save them to the specified directory
        pdfDoc.RasterizeToImageFiles(outputDirectory, "Page_Image_Page_{0}.png", options);

        // Inform the user that the process is complete
        Console.WriteLine("PDF pages have been successfully rasterized to images.");
    }
}

        // Define the path to the PDF file you want to rasterize

        // Create a new instance of IronPdf.PdfDocument from a PDF file
        PdfDocument pdfDoc = PdfDocument.FromFile(pdfPath);

        var options = new ImageSaveOptions
        {
            ImageFormat = ImageFormat.Png, // Specify the desired image format
            Dpi = 300 // Specify the resolution of the output images
        };

        // Define the directory where the images will be saved
        string outputDirectory = "OutputImages";

        // Convert each page of the PDF to an image and save them to the specified directory
        pdfDoc.RasterizeToImageFiles(outputDirectory, "Page_Image_Page_{0}.png", options);

        // Inform the user that the process is complete
        Console.WriteLine("PDF pages have been successfully rasterized to images.");
    }
}

Key Points:

• IronPDF is used to handle the conversion of PDF documents to images.
• The FromFile method loads the PDF document into an IronPdf.PdfDocument object.
• ImageSaveOptions allows customization of the image format and resolution.
• RasterizeToImageFiles method exports each page of the PDF to separate image files, naming them according to their page number.
• The images are saved to a specified output directory.

Ensure you have the IronPDF library installed in your project to use its functionalities. You can install it via NuGet Package Manager:
