PDF to JPG via cURL Command

Our Cloud APIs are built on REST architecture, so you may consider accessing them via cURL commands. Our APIs provide a powerful cloud-based solution with a range of benefits for PDF file processing in the cloud. By using the cURL commands, you can effortlessly initiate the PDF to JPG conversions routine. So, first we need to generate a JSON Web Token (JWT) based on ClientID and ClientSecret details retrieved from Aspose.Cloud dashboard. Please execute the following command in the terminal to generate the JWT token.

curl -v "https://api.aspose.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Now that we have a JWT token, please execute the following cURL command to perform PDF to JPG conversion online. The resultant JPG is returned in response object. However, in order to save the resultant JPG to local drive, please try using the -o argument.

curl -X GET "https://api.aspose.cloud/v3.0/pdf/converted.pdf/pages/1/convert/jpeg?width=800&height=800" \
-H  "accept: multipart/form-data" \
-H  "authorization: Bearer <JWT Token>" \
-o myResultant.jpg
