Convert PDF to EPUB in C# .NET

Please follow the instructions given below to accomplish the PDF to EPUB conversion in C# .NET.

PdfApi pdfApi = new PdfApi(clientSecret, clientID);

Create an object of PdfApi class where we pass client credentials as arguments.

var response = pdfApi.PutPdfInStorageToEpub("sourcefile.pdf", "resultant.epub", contentRecognitionMode: "Flow", null, null);

Call the API to convert input PDF file to EPUB format where we have used content recognition mode as Flow. The resultant file is then stored in cloud storage. The contentRecognitionMode can have either of the following values:

Turn PDF into EPUB using cURL Commands

Transforming PDFs into EPUB format becomes an intuitive and powerful process with Aspose.PDF Cloud and cURL commands. Aspose.PDF Cloud, a robust API for document manipulation, seamlessly integrates with cURL, offering developers a versatile solution for PDF to EPUB conversion. This approach not only simplifies the conversion but also ensures accuracy and preserves document structure and formatting during the transition.

The first step in this approach is to generate a JWT access token using the following command:

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=163c02a1-fcaa-4f79-be54-33012487e783&client_secret=c71cfe618cc6c0944f8f96bdef9813ac" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Once we have the JWT token, please execute the following command to convert PDF file to EPUB format.

curl -v "https://api.aspose.cloud/v3.0/pdf/{sourceFile}/convert/epub?outPath={resultantFile}&contentRecognitionMode=Flow" \
-X PUT \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}"

Replace sourceFile with the name of input PDF (available in cloud storage), resultantFile with the name of resultant file and accessToken with JWT access token generated above.


In conclusion, the realm of PDF to EPUB conversion unfolds two powerful approaches. The .NET SDK provides a native and robust solution for those who favor seamless integration within local environments, while the dynamic combination of Aspose.PDF Cloud and cURL commands introduces a cloud-based alternative, offering scalability and accessibility across diverse platforms. In short, Aspose.PDF Cloud stands as a pivotal tool, not merely for fulfilling conversion requirements but as a gateway to elevate document processing, making it the ultimate choice for developers navigating the complexities of modern document management.
