Hi David,
Thank you for contacting Syncfusion support.
Our HTML converter may generate blank PDFs while converting HTTPS sites to PDF. For converting HTTPS sites to PDF, the WebKit rendering engine requires OPENSSL libraries. So, please make sure the OPENSSL assemblies are available in the machine where the conversion takes place. Please refer to the below links for more details,
However, the below mentioned OPENSSL assemblies can be placed in the Windows system folder of the machine. (for 64-bit machine, it should be place in $SystemDrive\Windows\SysWOW64 and for 32-bit machine, it should be place in $SystemDrive\Windows\System32).
- libeay32.dll
- libssl32.dll
- ssleay32.dll
If you are hosting the application in the Azure environment, By default, some Azure websites do not have the OPENSSL assemblies. So, these assemblies should be added to the website explicitly. Please refer to the below links to add OPENSSL assemblies to the Azure website.
If still, you are facing the same issue, kindly provide more details such as complete input HTML file/URL (with all resources styles, scripts, etc.,), complete code snippet, environment details (OS, Bit version, RAM, etc), product version to reproduce the issue in our end. So, that it will be helpful for us to analyze and assist you further on this.
Regards,
Gowthamraj K
