How to Convert a PNG Array to PDF in Node.JS

When laying out a style sheet or sharing a set of images, it may be easier to compile your array in a PDF document rather than sending as a PNG. By sharing the images as PDF, you can control the size of the images as well as set your preferred viewing order. This API will allow you to instantly convert a PNG image array to PDF with one image per page. Varied image sizes are supported for input.

To use this API, run this command to install the SDK:

npm install cloudmersive-convert-api-client --save

You can also add this snippet to your package.json:

"dependencies": {
    "cloudmersive-convert-api-client": "^2.4.8"
  }

Then, you can call the function:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDocumentApi();
var inputFile1 = Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer); // File | First input file to perform the operation on.
var inputFile2 = Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer); // File | Second input file to perform the operation on.
var opts = { 
  'inputFile3': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Third input file to perform the operation on.
  'inputFile4': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Fourth input file to perform the operation on.
  'inputFile5': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Fifth input file to perform the operation on.
  'inputFile6': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Sixth input file to perform the operation on.
  'inputFile7': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Seventh input file to perform the operation on.
  'inputFile8': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Eighth input file to perform the operation on.
  'inputFile9': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Ninth input file to perform the operation on.
  'inputFile10': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer) // File | Tenth input file to perform the operation on.
};
var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
apiInstance.convertDocumentPngArrayToPdf(inputFile1, inputFile2, opts, callback);

With this, you can convert up to ten PNGs to PDF, to improve your ability to share images with partners and clients.

You can retrieve the API Key from the Cloudmersive website at no cost and with no commitment. This will provide you with 800 monthly calls across our library of APIs.
