How to convert a PDF to a single PNG image in Node.JS

Sometimes it’s better to turn that hulking PDF file into a giant PNG file. This can make it much easier to adjust colors for printing, for example. Whatever your reason might be, we have a great way to do this, one that will drastically reduce your time investment. Let’s dive straight into the how-to.

Using this dependency reference in our package.json file will install our client.

"dependencies": {
    "cloudmersive-convert-api-client": "^2.1.6"
  }

Now simply call our PDF conversion 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';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDocumentApi();
var inputFile = "/path/to/file"; // File | 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.convertDocumentPdfToPngSingle(inputFile, callback);

And just like that, we are already done. Now get out there and enjoy all your newly found free time!
