Simple HTML to PDF Conversion, high memory, high cpu load and 5min


we did some evaluation tests. A simple static html2pdf conversion takes minutes and a peak of 3GB memory test.zip (26.5 KB)
. Is this normal.

class Program
static void Main(string[] args)
if (args.Count() > 1)
// Create HTML load options
HtmlLoadOptions htmloptions = new HtmlLoadOptions();
htmloptions.IsRenderToSinglePage = true;
htmloptions.IsEmbedFonts = true;
// Load HTML file
Document doc = new Document(args[0], htmloptions);
// Convert HTML file to PDF



The conversion time depends upon various factors to be noticed i.e. structure and complexity of the content, environment where API is being used, etc. Would you kindly share the complete environment details with us i.e. OS Name and Version, Installed RAM Memory, Application Type, Target Framework. We will test the scenario in our environment and address it accordingly.


here are the specs.

Windows 10 Pro 2004
Framework 4.6.2
Console Application (attached)Apose.Html2Pdf.Test.zip (8.1 KB)
