File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected documents.
PageRange
String Default: 1-2000Set page range. Example 1-10 or 1,2,5.
Wysiwyg
Bool Default: FalsePersist exact formatting using text boxes.
Annotations
Collection Default: textBoxSet how PDF annotations are handled in the DOCX output: choose textBox to place each annotation as an editable text box near its anchor, comment to convert annotations into Word comments attached to the relevant text, or none to omit all annotations from the result.
OcrMode
Collection Default: autoDefines how OCR is applied during conversion. Auto performs OCR only when needed. Force applies OCR to all pages. Never disables OCR entirely.
OcrLanguage
Collection Default: autoConfigure the OCR language for text recognition. If auto-detection fails, manually specify the language.
Values: auto ar ca zh da nl en fi fr de el ko it ja no pl pt ro ru sl es sv tr ua thOcrEngine
Collection Default: nativeSelect the OCR engine to use for text recognition. Each engine may produce slightly different results. If Tesseract is selected, the OcrLanguage property must be explicitly set, as automatic language detection is not supported.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.

A detailed guide to PDF to DOCX conversion using C#
Our PDF to DOCX converter is an API tool designed to convert PDF (Portable Document Format) files into editable DOCX (Microsoft Word) files. This conversion allows users to edit and manipulate the content of a PDF document in a docx processing program like Microsoft Word. A PDF to DOCX converter is a versatile and practical tool that simplifies converting PDF documents into Microsoft Word-compatible DOCX files. It can be extremely useful and serves various purposes described below.
Editability
With our PDF to DOCX converter, you can convert textual or scanned PDF files into editable Word documents. This means that once converted, you can easily modify text, formatting, and other elements within the DOCX file using Microsoft Word or similar word-processing software.
Preservation of Formatting
Our converter will strive to retain the original formatting and layout of the PDF document as closely as possible during the conversion process. This ensures that the converted DOCX file closely resembles the original PDF.
Customization Options
The PDF to DOCX API provides options to customize the output, such as selecting specific pages to convert, enabling or disabling OCR, and specifying the OCR language. It also allows you to convert password-protected PDF documents.
Compatibility
The resulting DOCX files from a PDF to DOCX converter are compatible with popular docx processing software like Microsoft Word, Google Docs, LibreOffice, and more, making it easy to work with the converted documents.
ConvertAPI PDF to Word converter
In this tutorial, we will go through the C# PDF to DOCX conversion implementation, covering everything from a file upload to the converted DOCX output download.
ConvertAPI is a REST API service; however, we created a ConvertAPI DotNet library so you can integrate it without worrying about any HTTP calls at all.
You can download the ConvertApi package from NuGet, install it into your ASP.NET C# project, and you are all set up!

Sign up for a free account and get your API Token in your account dashboard. You can read more about different authentication methods in our docs.

3. Set the conversion parameters
Once you have our library installed and received your ConvertAPI API Token, you can modify the conversion parameters using our live demo. Once you are happy with the conversion result, you will find an auto-generated code snippet at the bottom of the page!
4. Convert the PDF files to MS Office Word documents using C# programming language
Here is an example code snippet showing how simple it actually is to convert a PDF to an editable DOCX document:
var convertApi = new ConvertApi("api_token");
var convert = await convertApi.ConvertAsync("pdf", "docx",
new ConvertApiFileParam("File", @"C:\path\to\my_file.pdf")
);
await convert.SaveFilesAsync(@"C:\converted-files\");
That's all! Using ConvertAPI, you can effortlessly integrate a PDF to Word conversion into your ASP.NET project. You can find a complete list of conversion parameters on our live demo page.
