Convert pdf to jpg using Java cloud SDK

PDF files are widely used over the internet for information and data sharing. Now in order to view these documents, we need to use specific applications but if we save PDF as JPG, it can be viewed on any platform and any device. Also, the size of the file is greatly reduced. Furthermore, we can easily develop a PDF viewer because, once we save a PDF as an image, we can load the image in any browser. Therefore, in this article, we are going to discuss the details to convert PDF to JPG online using Cloud API.

PDF to Image using cURL Commands

We can also convert PDF to Image format using cURL commands over the command line terminal. However, in order to access Aspose.PDF Cloud, we need to first generate a JSON Web Token (JWT) based on your individual client credentials. Please execute the following command to generate the JWT token.

curl -v "https://api.aspose.cloud/connect/token" \
-d "grant_type=client_credentials&client_id=bbf94a2c-6d7e-4020-b4d2-b9809741374e&client_secret=1c9379bb7d701c26cc87e741a29987bb" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Once the JWT is generated, please execute the following command to convert PDF to image and save the output in cloud storage.

curl -v -X PUT "https://api.aspose.cloud/v3.0/pdf/input.pdf/pages/1/convert/jpeg?outPath=resultant.jpg&width=800&height=1000" \
-H  "accept: application/json" \
-H  "authorization: Bearer <JWT Token>"
