Html to PDF conversion taking long time with the ExpertPDF/Aspose.Pdf components

I am trying to generate a PDF file based on a dynamically generated HTML report that our webapplication has generated.

The HTML generation and rendering is fast (1-4s) except in older browsers (IE6/IE7), but when I use either one of the mentioned PDF components to generate th开发者_如何学运维e PDF version, it can take up to several minutes.

For instance I have an HTML report that contains only text - approximately 1 million characters - which takes ~28s to convert to a PDF file, which is only 1.15MB in size and ~250 pages.

Is there any way to optimize the HTML, to make the job easier for the PDF components?

Convert HTML to PDF in .NET

It would be better if you could share a sample input HTML file along with the code snippet. Moreover, we have recently published a newer version of Aspose.Pdf for .NET (version 6.3.0). Please try with that and see if it helps in your scenario. If you still find the same issue then I would recommend you to post the query along with input HTML and code snippet in Aspose.Pdf forum. Our support team will further investigate it and guide you accordingly.

Better try to avoid HTML --> PDF conversion if you can - it makes lots of problems sometimes.

I've tried two other approaches (both are free of charge) and both are working very well, although are much different:

• Use Microsoft Reporting RDLC templates. Has nice and easy designer in Visual Studio. What you have to do is just to create a template, fill it with some data in code and that's all. It's fast, easy to use and maintain. I'm currently using that in many webapps and I'm very happy with it.
• Use iTextSharp library. It blazingly fast. You can generate PDFs from XML or from code (which can be a drawback in complex PDFs, but gives you full control if you need it).

You can try XF Rendering Engine from Ecrion Software(www.ecrion.com). They have also a WYSIWYG designer.

1. First what i did to improve performance of conversion is to convert my report html in box structure with the help of designer
2. I used this component Winnovative HTML to PDF Converter
