Convert Word to JPEG in Java

GroupDocs.Conversion Cloud SDK for Java provides an efficient and reliable solution for converting PDF files into Excel workbooks. Some of the salient features the REST API offers:

Step 1: Configure API Credentials

Configuration configuration = new Configuration();
configuration.setClientId("YOUR_CLIENT_ID");
configuration.setClientSecret("YOUR_CLIENT_SECRET");

ConvertApi convertApi = new ConvertApi(configuration);
FileApi fileApi = new FileApi(configuration);

Step 2: Upload Word Document to Cloud Storage

File file = new File("sample.docx");
UploadFileRequest uploadRequest =
        new UploadFileRequest("sample.docx", file, null);
fileApi.uploadFile(uploadRequest);

Step 3: Define JPG Conversion Settings

ConvertSettings settings = new ConvertSettings();
settings.setFilePath("sample.docx");
settings.setFormat("jpg");
settings.setOutputPath("converted/word-to-jpg");

Step 4: Convert Word Document to JPG

ConvertDocumentRequest request =
        new ConvertDocumentRequest(settings);

convertApi.convertDocument(request);
System.out.println("Word document successfully converted to JPG images.");

DOCX to JPEG using cURL

Alternatively, if you prefer using command line operations to convert Word document pages to JPEG images, you may try using GroupDocs.Parser Cloud with cURL commands.

curl -v "https://api.groupdocs.cloud/v2.0/conversion" -X POST \
-H "accept: application/json" \
-H "authorization: Bearer {ACCESS_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
  "FilePath": "sample.docx",
  "Format": "jpg",
  "OutputPath": "converted/word-to-jpg"
}'
