Error Handling

It is recommended that you implement error handling to catch errors that the API may return, see the example code below. A list of status codes and their description can be found here.

try {
    // call the API 
catch(Pdfcrowd.Error why) {
    // print the error
    System.err.println("Pdfcrowd Error: " + why);

    // print the error code
    System.err.println("Pdfcrowd Error Code: " + why.getCode());

    // print the error message
    System.err.println("Pdfcrowd Error Message: " + why.getMessage());


  • Refer to the API Status Codes page if the API returns an error.
  • You can use setDebugLog and getDebugLogUrl to get detailed info about the conversion, such as load errors, load times, browser console output, etc.
