DOC to PDF in C#

doc to pdf in C#

The Portable Document Format (PDF) is one of the popular document formats for information sharing over the internet. It’s due to the amazing capabilities of preserving document formatting/fidelity when viewing on various platforms. At the same time, Word documents (DOC, DOCX, etc) are also widely used for official information storage and sharing in organizations, universities, govt institutes, etc. But the challenge with Word documents is that you need specialized applications to view them. Also, in case the fonts used inside Word documents are not installed on the system, the formatting of documents is disturbed. Owing to these constraints, one of the viable solutions is to convert the DOC files to PDF format, and in this article, we are going to discuss the conversion of DOC to PDF in C#.

Word processing API

Aspose.Words Cloud is our award-winning REST API-based MS Word, Open Office, OpenDocument, and other popular formats processing API. The details regarding the complete list of supported formats can be found over Supported File Formats. Furthermore, the API enables you to create, edit as well as convert files to other formats including PDF, XPS, SVG, PCL, JPEG and much more. Therefore, perform all the document processing operations within the cloud without MS Office automation or any other software installed. Nevertheless, in order to facilitate our customers, we have created Aspose.Words Cloud SDK for .NET which is a wrapper around Aspose.Words REST API. So you could seamlessly integrate Microsoft Word® document generation, manipulation, conversion & inspection features into your own .Net applications.


Please note that in order to get started, the first step is to install the Cloud SDK either from NuGet or GitHub. So please execute the following command in the Nuget package manager console to install the SDK.

Please note that under the free subscription plan, you can perform up to 150 free document processing requests. After you are convinced of the capabilities of REST APIs, you may consider opting for an account subscription for as low as $0.005 / API Call under pay as you go model. For more information, please visit the Pricing plan.

DOC to PDF in C#

Please follow the steps given below to convert DOC file already available on cloud storage to PDF conversion using C# .NET code.

Convert DOC to PDF using cURL command

Aspose.Words Cloud SDK for .NET is a programming SDK developed on top of Aspose.Words Cloud REST API. Our Cloud REST APIs can be accessed from any platform and the cURL commands are one of the easiest ways. However, in order to use APIs via cURL commands, we need to first generate a JWT access token based on Client ID and Client Secret details.

 curl -v "" \
-d "grant_type=client_credentials&client_id=718e4235-8866-4ebe-bff4-f5a14a4b6466&client_secret=388e864b819d8b067a8b1cb625a2ea8e" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Once the JWT token has been generated, access GetDocumentWithFormat API to perform DOC to PDF conversion.

curl -X GET "" \
-H  "accept: application/octet-stream" \
-H  "Authorization: Bearer <JWT Token>"
