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: Apikeyvar 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!
