PDF to JPEG

POST/GET endpoint:

https://api.pdf.co/v1/pdf/convert/to/jpg

Code Sample (PDF to JPEG):

var Bytescoutio = require('bytescoutio');
var defaultClient = Bytescoutio.ApiClient.instance;

// Configure API key authorization: api_key
var api_key = defaultClient.authentications['api_key'];
api_key.apiKey = "YOUR API KEY"
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//api_key.apiKeyPrefix['x-api-key'] = "Token"

var api = new Bytescoutio.DefaultApi()

var opts = { 
  'pages': pages_example, // {String} Comma-separated list of page indices (or ranges) to process. Leave empty for all pages. Example: '0,2-5,7-'.
  'name': name_example, // {String} File name for generated result.
  'url': url_example // {String} URL of the source PDF file.
};

var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
api.pdfConvertToJpgPost(opts, callback);

PDF to PNG

POST/GET endpoint:

https://api.pdf.co/v1/pdf/convert/to/png

Code Sample (PDF to PNG):

var Bytescoutio = require('bytescoutio');
var defaultClient = Bytescoutio.ApiClient.instance;

// Configure API key authorization: api_key
var api_key = defaultClient.authentications['api_key'];
api_key.apiKey = "YOUR API KEY"
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//api_key.apiKeyPrefix['x-api-key'] = "Token"

var api = new Bytescoutio.DefaultApi()

var opts = { 
  'pages': pages_example, // {String} Comma-separated list of page indices (or ranges) to process. Leave empty for all pages. Example: '0,2-5,7-'.
  'name': name_example, // {String} File name for generated result.
  'url': url_example // {String} URL of the source PDF file.
};

var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
api.pdfConvertToPngPost(opts, callback);

PDF to TIFF

POST/GET endpoint:

https://api.pdf.co/v1/pdf/convert/to/tiff

Code Sample (PDF to TIFF):

var Bytescoutio = require('bytescoutio');
var defaultClient = Bytescoutio.ApiClient.instance;

// Configure API key authorization: api_key
var api_key = defaultClient.authentications['api_key'];
api_key.apiKey = "YOUR API KEY"
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//api_key.apiKeyPrefix['x-api-key'] = "Token"

var api = new Bytescoutio.DefaultApi()

var opts = { 
  'pages': pages_example, // {String} Comma-separated list of page indices (or ranges) to process. Leave empty for all pages. Example: '0,2-5,7-'.
  'name': name_example, // {String} File name for generated result.
  'url': url_example // {String} URL of the source PDF file.
};

var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
api.pdfConvertToTiffPost(opts, callback);
