How to Convert a PDF to an Image

The following steps and C# sample code illustrates converting a PDF file to a variety of image formats.

Steps for Converting

1. Create a PdfRasterizer object instance using the source PDF document.
2. Add the Draw method by specifying the file path to save the image, the image type as ImageFormat.jpeg, and the image size as ImageSize.Dpi72.
3. Repeat step two, but change the file type to ImageFormat.png and ImageSize.Dpi300.
4. Repeat step two, but change the file type to ImageFormat.tiff and ImageSize.Dpi300.

Sample code - C# (PDF to JPG)

PdfRasterizer rasterizer = new PdfRasterizer("doc-a.pdf");
rasterizer.Draw("output.jpg", ImageFormat.Jpeg, ImageSize.Dpi72);

Sample code - C# (PDF to PNG)

PdfRasterizer rasterizer = new PdfRasterizer("doc-a.pdf");
rasterizer.Draw("output.png", ImageFormat.Png, ImageSize.Dpi300);

Sample code - C# (PDF to TIFF)

PdfRasterizer rasterizer = new PdfRasterizer("doc-a.pdf");
rasterizer.Draw("output.png", ImageFormat.Png, ImageSize.Dpi300);

Converting a PDF to multi-page TIFF

Create a multipage TIFF from a PDF by using the PdfRasterizer class's DrawToMultiPageTiff method. The following steps and C# sample code shows you how.

Steps for Converting

1. Create a PdfRasterizer object instance using the source PDF document.
2. Add the DrawToMultiPageTiff method by specifying the file path to save the image, the image type as TiffWithCcitGroup4, and the image size as Dpi150.
3. Repeat step two, but change the type to GIF.
4. Repeat step two, but change the type to BMP.

Sample code - C# (Multi-page TIFF from PDF)

PdfRasterizer rasterizer = new PdfRasterizer("doc-a.pdf");
rasterizer.DrawToMultiPageTiff("output.tiff", ImageFormat.TiffWithCcitGroup4, ImageSize.Dpi150);

Sample code - C# (PDF to GIF)

PdfRasterizer rasterizer = new PdfRasterizer("doc-a.pdf");
rasterizer.Draw("output.gif", ImageFormat.Gif, ImageSize.Dpi150);

Sample code - C# (PDF to BMP)

PdfRasterizer rasterizer = new PdfRasterizer("doc-a.pdf");
rasterizer.Draw("output.bmp", ImageFormat.Bmp, ImageSize.Dpi96);
