Troubleshooting

  • Refer to the API Status Codes page if the API returns an error.
  • You can use -debug-log to get detailed info about the conversion, such as load errors, load times, browser console output, etc.
  • Check the FAQ.
  • You can use our JavaScript library to resolve rendering problems, such as missing content or blank pages.
    Just use -custom-javascript with libPdfcrowd.highlightHtmlElements method call to visualize all HTML elements. See the backgrounds example , borders example and helper JavaScript library documentation.
