🚀 Convert HTML to PDF using Node.js
Here’s a step-by-step guide for converting a PDF document to HTML using Node.js:
📌 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: Upload the input HTML file to the Cloud storage:
const fs = require("fs");
const uploadRequest = new UploadFileRequest("input.html", fs.createReadStream("input.html"));
await fileApi.uploadFile(uploadRequest);
📌 Step 3: Set HTML to PDF conversion options:
const settings = new ConvertSettings();
settings.filePath = "input.html";
settings.format = "pdf";
settings.outputPath = "converted/output.pdf";
const request = new ConvertDocumentRequest(settings);
await convertApi.convertDocument(request);
console.log("✅ The HTML successfully converted to PDF.");

💻 Convert HTML to PDF with cURL
Do you prefer CLI? You can also convert HTML to PDF using cURL with GroupDocs.Conversion Cloud API endpoint.
- ✅ This method is ideal for automation pipelines and script-based conversions.
Step 1: Get JWT Access Token
curl -v "https://api.groupdocs.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"
Step 2: Convert HTML to PDF
curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{ \"StorageName\": \"default\", \"FilePath\": \"{sourcePDF}\", \"Format\": \"html\", \"OutputPath\": \"{finalOutput}\"}"
Replace sourceFile, resultantFile, and accessToken with actual values.
- Now in order to save the PDF on local drive, you may consider using the following cURL command:
curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{ \"StorageName\": \"default\", \"FilePath\": \"{sourceFile}\", \"Format\": \"html\"}" \
-o "myOutput.html"
