JPEG2000 to JPG conversion in C# .NET.

JPEG2000 (JP2) offers superior compression and image quality, but its widespread adoption has been limited due to compatibility issues across various platforms & applications. In contrast, the JPG (or JPEG) format remains the universal standard for image sharing, web display, and application integration. Therefore, the importance of converting JPEG2000 to JPG cannot be overstated. Therefore, for web usage, digital sharing, or application integration, the ability to convert JPEG2000 to JPG ensures seamless image compatibility and enhances the accessibility and usability of our digital assets. In this article, we are going to explore the significance of this conversion and learn how to perform it effortlessly using .NET REST API.

Convert JPEG2000 to JPG in C# .NET

This section explains the details on how Aspose.Imaging Cloud SDK for .NET handles the conversion process seamlessly, while preserving image quality and ensuring compatibility with the widely supported JPG format using C# .NET.

ImagingApi imagingApi = new ImagingApi(clientSecret, clientID, baseUrl: "");

Create an instance of ImagingApi class where we pass client credentials and baseURL as arguments.

imagingApi.UploadFile(new UploadFileRequest("input.jp2", imageStream));

Upload the input JPEG2000 image to cloud storage.

ConvertImageRequest requestInstance = new ConvertImageRequest("input.jp2", "jpg");

Create an instance of ConvertImageRequest class where pass the name of input JPEG2000 image and the resultant format as JPG.

var resultant = imagingApi.ConvertImage(requestInstance);

Call the API to convert JPEG2000 to JPEG format and save the output in stream instance.

saveToDisk(resultant, "Resultant.jpeg");

Our custom method to save the resultant JPEG image to local drive.

The sample JPEG2000 used in the above example can be downloaded from UpdateJPEG2000SampleImage.jp2 and the resultant JPG from Reusltant.jpg.

JPG2 to JPG using cURL Commands

Converting JPEG2000 to JPEG using Aspose.Imaging Cloud and cURL commands offers a flexible and scriptable solution for developers seeking to automate image conversion tasks. One of the key benefits of this approach is its simplicity and ease of integration into existing workflows and automation pipelines. Therefore, with just a few simple commands, you can initiate and manage the conversion process without the need for complex code or additional libraries.

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

curl -v "" \
 -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, the following cURL command enables you to perform a versatile and efficient solution for JPEG2000 to JPEG conversion.

curl -v "{sourceImage}/convert?format=jpg" \
-X GET \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-o "Reusltant.jpg"

Replace sourceImage with the name of input JPEG2000 image already available in cloud storage, and accessToken with JWT access token generated above.


In conclusion, whether you choose to utilize Aspose.Imaging Cloud SDK for .NET or integrate Aspose.Imaging Cloud with cURL commands, the conversion of JPEG2000 to JPEG is made seamless and efficient. Both approaches offer versatile solutions for automating image conversion tasks, empowering you to effortlessly bridge the gap between JPEG2000 and JPEG formats.
