Hi Sheeban, 

We have tried to reproduce the reported issue in our side with provided sample, but the extra page is not added in our side. We suspect the issue may occurs with images and styles, could you please share us the complete HTML file with (images, styles etc.,). So that it will be helpful for us to analyze further on this. We have attached the output PDF document, which is generated in our side with provided sample.  


However, please try the conversion with our Blink rendering engine and let us know the result. Please refer below link for more information about Blink rendering engine.

Hi Sheeban, 
 
We have checked the reported extra page issue with provided sample, the content is height in the PDF document exceeds the page height. So it is adding another page, but there is no content to draw in that page. To resolve this issue, we can adjust the content size in PDF document using ViewPortSize property. Kindly try the conversion with below settings and update us the details.  
 
//Set viewport size to adjust content size.  
settings.ViewPortSize = new Size(1280, 0); 
 
Please let us know if you need any further assistance on this.

Hi  Gowthamraj,

Is there any standard to set the ViewPort Size. As I have seen on few forms that somewhere you are suggesting (1500, 0) and  (800, 0). When I increased x it's PDF size get shrink. So can you please guide what is the standard to follow this size?


PV Prakash Viswanathan Syncfusion Team August 3, 2021 04:19 PM UTC

Hi Sheeban, 

We internally using QtWebKit rendering engine for converting HTML to PDF. The viewport size will be set to the QtWebKit browser windows size. Based on that size, the content will be scaled in the output PDF document. Also it is depends on the input HTML file content width, so we need to set the viewport size based on our requirement. You can check the same behavior in chrome print preview with custom scale option. 

Please refer below link for more information about viewport size.
