A unique license key string is generated for each purchase. In order to unlock the HTML to PDF Converter product, you have to set the LicenseKey property of the PdfConverter class (when converting to PDF) or of the ImgConverter class (when converting to image) with the license key string you have received after the product purchase.

Also, if Document, HtmlToPdfElement, HtmlToImageElement or HtmlToPdfArea objects are used, the LicenseKey property needs to be set for each object that is instantiated.

The license key contains the information about the purchased product like the product version and license type and is uniquely associated with an order ID.

Sample Code

Here is how you can set the License Key in code:

pdfConverter.LicenseKey = "license key here";
