Let’s develop understanding about the conversion code snippet.

var config = new Configuration { ClientId = clientID, ClientSecret = clientSecret };
var wordsApi = new WordsApi(config);

Create an object of Configuration and WordsApi instance where client credentials are used as arguments.

var response = new GetDocumentWithFormatRequest(inputFile, format: format, outPath: resultant);

Create an instance of GetDocumentWithFormat object where we provide input RTF name, resultant format as PDF and name of resultant PDF document as arguments.


Now, call this method to initialize the RFT to PDF conversion operation. The resultant PDF is then stored in cloud storage.

If we skip the outPath argument, the resultant PDF will be returned in response stream.

The input RFT file used in the above example can be downloaded from input-sample.rft.

Convert Rich Text Document to PDF using cURL Commands

Another way to convert RTF to PDF is by using cURL commands. cURL is a command-line tool that allows you to transfer data from and to servers using various protocols, including HTTP, FTP, and SMTP. With cURL, you can easily convert RTF files to PDF by making API requests to online RTF to PDF converter services.

In this article, we’ll show you how to use cURL commands to convert RTF to PDF, providing a step-by-step guide that includes valuable information on available online RTF to PDF converter services, how to authenticate with their APIs, and how to perform the conversion process using cURL commands.

So, the first step is to generate the JWT access token (based on client credentials) using the following command:

curl -v "https://api.aspose.cloud/connect/token" \
-d "grant_type=client_credentials&client_id=bb959721-5780-4be6-be35-ff5c3a6aa4a2&client_secret=4d84d5f6584160cbd91dba1fe145db14" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Once we have accessToken, please execute the following command that loads the input RFT document from cloud storage and converts it to PDF format. The resultant PDF is also stored in cloud storage.

curl -v "https://api.aspose.cloud/v4.0/words/{inputFile}?format=PDF&outPath={resultantFile}" \
-X GET \
-H  "accept: application/octet-stream" \
-H  "Authorization: Bearer {accessToken}"

Replace {inputFile} with the name of input RFT document present in Cloud storage, {accessToken} with JWT access token generated above and {resultantFile} with name/path to resultant PDF file.


Converting RTF to PDF is a common requirement for many users, and there are several ways to achieve this goal, including using C# .NET, cloud-based services, and cURL commands.
