Tips & Tricks

The API lets you convert a web page, a local HTML file, or a string containing HTML. The result of the conversion can be stored to a local file, to a stream object or to a variable. See the conversion input section for more details.

The best way to start with the API is to choose one of the examples and once you get it working, you can:

You can also use these HTML related features:

  • You can use the following classes in your HTML code which hide/remove elements from the output:
    • pdfcrowd-remove - sets display:none!important on the element
    • pdfcrowd-hide - sets visibility:hidden!important on the element
  • You can switch to the print version of the page (if it exists) with setUsePrintMedia.
  • You can force a page break with
    <div style="page-break-before:always"></div>
  • You can avoid a page break inside an element with the following CSS
    img { page-break-inside:avoid }
  • You can use setOnLoadJavascript or setCustomJavascript to alter the HTML contents with a custom JavaScript. In addition to the standard browser APIs, the custom JavaScript code can use helper functions from our JavaScript library.

Error Handling

try 
{
    // call the API 
}
catch(\Pdfcrowd\Error $why) 
{
    // print error
    error_log("Pdfcrowd Error: {$why}\n");

    // print just error code
    error_log("Pdfcrowd Error Code: {$why->getCode()}\n");

    // print just error message
    error_log("Pdfcrowd Error Message: {$why->getMessage()}\n");

    // or handle the error in your way
}

Troubleshooting

  • Check API Status Codes in case of the error code is returned.
  • You can use setDebugLog and getDebugLogUrl to get detailed info about the conversion, such as conversion errors, time, console output.
  • You can use our JavaScript library to resolve rendering problems, such as missing content or blank pages.
    Just use setCustomJavascript with libPdfcrowd.highlightHtmlElements method call to visualize all HTML elements. See the example and helper JavaScript library documentation.
  • Take a look at the FAQ section.
