JPG to PDF Conversion in Node.js

Here’s how to convert PDF file to JPG images using GroupDocs.Conversion Cloud SDK in a Node.js project:

Step 1: Import SDK and configure API:

const { Configuration, ConvertApi, FileApi, UploadFileRequest, ConvertSettings, ConvertDocumentRequest } = require("groupdocs-conversion-cloud");
const config = new Configuration("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");
const convertApi = new ConvertApi(config);
const fileApi = new FileApi(config);

Step 2: Now upload the input PDF file to the Cloud storage:

const fs = require("fs");
const uploadRequest = new UploadFileRequest("source.jpg", fs.createReadStream("source.pdf"));
await fileApi.uploadFile(uploadRequest);

Step 3: Set conversion options for (PDF → JPG):

const settings = new ConvertSettings();
settings.filePath = "source.pdf";
settings.format = "jpg";
settings.outputPath = "converted/resultant.jpg";

const request = new ConvertDocumentRequest(settings);
await convertApi.convertDocument(request);
console.log("The PDF to JPG conversion completed successfully.");

Use cURL for PDF to JPG Conversion

Another approach for converting a PDF file to JPG image is the usage of cURL commands. The usage of cURL commands offers several advantages, particularly for developers and businesses looking for a quick, automated, and scriptable approach to document transformation. It’s a lightweight & fast solution, offering cross-platform compatibility that requires minimal coding effort.

Why Use REST API / cURL?:

  • Perfect for DevOps and serverless functions.
  • Lightweight and easy to integrate.
  • No SDK overhead.

The first step is to generate a personalized Java Web Access Token and then, execute the following command to perform PDF to JPG image conversion.

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 "{  \"StorageName\": \"internal\",  \"FilePath\": \"{inputFile}\",  \"Format\": \"jpg\",  \"resultantPath\": \"{myResultant}\"}"

Please replace inputFile with the name of input PDF file, resultantPath with the name of resultant JPG image and ACCESS_TOKEN with a personalized JWT access token.
