Convert PDF to Picture using cURL Commands

The conversion of PDF documents to JPG images using Aspose.PDF Cloud and cURL commands provides a straightforward and efficient solution for document conversion. This approach ensures accuracy in preserving the quality and layout of the resultant JPG images, maintaining the integrity of the original PDF content. Furthermore, its cloud-based architecture ensures scalability and accessibility, allowing you to handle document conversion tasks efficiently without the need for complex local installations.

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"

Now, please execute the following command to convert PDF to picture format and store the output on local drive.

curl -v "https://api.aspose.cloud/v3.0/pdf/sourceFile.pdf/pages/1/convert/jpeg?width=600&height=800" \
-X GET \
-H "accept: multipart/form-data" \
-H "authorization: Bearer {accessToken}" \
-o "resultant.jpg"

In case we need to load the PDF file from cloud storage and also want to store the output in cloud storage, please execute the following command.

curl -v "https://api.aspose.cloud/v3.0/pdf/{sourceFile}/pages/2/convert/jpeg?outPath={resultantFile}&width=800&height=1000" \
-X PUT \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-d {}

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


In conclusion, the process of converting PDF documents to JPG images stands as a pivotal aspect of modern document management and content distribution. Throughout this discussion, we’ve explored various approaches to achieve this conversion, ranging from leveraging the Aspose.PDF Cloud SDK for .NET to utilizing cURL commands with Aspose.PDF Cloud API. Regardless of the method chosen, we can easily achieve our goal to streamline the document processing workflows and unlock the full potential of digital content.
