Convert PDF to other file formats using C#

How to convert PDF files to word, tiff, svg, image files? It is very easy job to convert PDF file in C# using XDoc.PDF.

We could simply use class PDFDocument conversion methods to export PDF document to Microsoft Word (.docx), tiff, JPG image files in a single method.

Convert to Word (.docx)

The following C# source code will tell you how to use XDoc.PDF SDK to convert PDF document to Microsoft Word document.

• Load a PDF file to construct a PDFDocument object
• Utilize method ConvertToDocument() to convert PDF to .docx file

            PDFDocument doc = new PDFDocument(@"C:\demo.pdf");
            doc.ConvertToDocument(DocumentType.DOCX, @"C:\output.docx");

You can also easily convert scanned PDF to editable Word document using XDoc.PDF and OCR C# library. View step by step guides at How to convert scanned pdf to word .docx using C#

Convert to multi-page TIFF image

The C# code below offers you a piece of C# demo code to convert PDF to multi-page TIFF image file. You may directly copy and paste it into your C# testing project.

            //  Open file
            PDFDocument doc = new PDFDocument(@"W:\Projects\Test-Files\file1.pdf");
            //  Convert whole PDF document to TIFF file
            doc.ConvertToDocument(DocumentType.TIFF, @"W:\Projects\Test-Output\demo.tif");

You could customize the converted TIFF image file with the following image options

• Color: the converted TIFF image color setting
• Compression: the tiff image compression scheme
• Resolution: the TIFF image resolution setting
• Zoom: use more pixel to render the PDF page if needed.

Convert to SVG, HTML web pages

Like other file conversion, you can use method PDFDocument.ConvertToVectorImages() to convert PDF to SVG files directly using C# code. Every PDF page will be converted to one SVG file.

            PDFDocument doc = new PDFDocument(@"W:\Projects\Test-Files\file1.pdf");
            doc.ConvertToVectorImages(ContextType.SVG, @"W:\Projects\Test-Output\pdf-convert-pdf-to-svg\", "file1-", RelativeType.SVG);

You can apply the following option to customize the converted SVG vector image files.

• RelativeType : embed image resource files, font resource files, and other files inside the SVG file or not

Convert to Text file (.txt)

To convert PDF to text file in C#, you may need apply right text encoding format. The following C# sample source code show how to convert PDF text content to a .txt file with UTF8 character encoding.

            using (Stream inStream = File.Open(@"W:\Projects\Test-Files\unicode-test-file.pdf", FileMode.Open, FileAccess.Read))
            {
                using (MemoryStream ms = new MemoryStream())
                {
                    //  Convert PDF to TXT from file stream to memory stream.
                    DocumentConverter.ToDocument(inStream, ms, FileType.DOC_TXT);

                    //  Get String from the data bytes (in UTF-8)
                    String content = Encoding.UTF8.GetString(ms.ToArray());

                    //  Get data bytes (in Unicode) from String.
                    byte[] dataBytes = Encoding.Unicode.GetBytes(content);
                    //  ...
                }
            }

Convert to JPG, PNG, bitmap images

            PDFDocument doc = new PDFDocument(@"W:\Projects\Test-Files\test-file.pdf");
            doc.ConvertToImages(ImageType.JPEG, @"W:\Projects\Test-Output\pdf-convert-pdf-to-jpg\", "test-file");
