You might have heard about how Apryse has a world-class document converter. Our Apryse SDK can easily transform HTML to PDF. The portability of a PDF allows you to access content from webpages across multiple devices both on- and off-line.
Below are a few code snippets to convert HTML to PDF.
Convert HTML to PDF in C#
using pdftron;
using pdftron.Common;
using pdftron.PDF;
using pdftron.SDF;
namespace ConsoleApp1
{
internal class Program
{
static void Main(string[] args)
{
try {
PDFNet.Initialize(PDFTronLicense.License);
HTML2PDF.SetModulePath(PDFTronLicense.ModulePath);
using (PDFDoc doc = new PDFDoc())
{
HTML2PDF converter = new HTML2PDF();
// Our HTML data
string html = "<html><body><h1>Heading</h1><p>Paragraph.</p></body></html>";
// Add html data
converter.InsertFromHtmlString(html);
// Note, InsertFromHtmlString can be mixed with the other Insert methods.
converter.Convert(doc);
doc.Save("output.pdf", SDFDoc.SaveOptions.e_linearized);
}
}
catch (PDFNetException e)
{
Console.WriteLine(e.Message);
}
}
}
} The above code could easily be modified to convert the input file to one of Apryse’s supported document formats by changing the document format enumeration.
