Hi Abhishek,

Thanks for contacting support.

As per my understanding, you need to convert PDF file to HTML format and save the output in a Byte Array. If so is the case, then please try using the following code snippet (very much similar to the one you have shared earlier). In case I have not properly understood your requirement, please feel free to contact.

[C#]

Document doc = new Document("c:/pdftest/record_275889686.pdf");

// tune conversion params
HtmlSaveOptions newOptions = new HtmlSaveOptions();
newOptions.RasterImagesSavingMode = HtmlSaveOptions.RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground;
newOptions.FontSavingMode = HtmlSaveOptions.FontSavingModes.SaveInAllFormats;
newOptions.PartsEmbeddingMode = HtmlSaveOptions.PartsEmbeddingModes.EmbedAllIntoHtml;
newOptions.LettersPositioningMethod = HtmlSaveOptions.LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss;
newOptions.SplitIntoPages = false; // force write HTMLs of all pages into one output document

newOptions.CustomHtmlSavingStrategy = new HtmlSaveOptions.HtmlPageMarkupSavingStrategy(SavingToStream);

// we can use some non-existing path as result file name - all real saving will be done
// in our custom method SavingToStream() (it follows this one)
string outHtmlFile = @"Z:\SomeNonExistingFolder\SomeUnexistingFile.html";
doc.Save(outHtmlFile, newOptions);

MemoryStream stream = new MemoryStream();
doc.Save(stream);

byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
    int read;
    while ((read = stream.Read(buffer, 0, buffer.Length)) > 0)
    {
        ms.Write(buffer, 0, read);
    }
    ms.ToArray();
}

Console.WriteLine(buffer.Length);
stream.Close();

private static void SavingToStream(HtmlSaveOptions.HtmlPageMarkupSavingInfo htmlSavingInfo)
{
    byte[] resultHtmlAsBytes = new byte[htmlSavingInfo.ContentStream.Length];
    htmlSavingInfo.ContentStream.Read(resultHtmlAsBytes, 0, resultHtmlAsBytes.Length);
    // here You can use any writable stream, file stream is taken just as example
    string fileName = "stream_out.html";
    Stream outStream = File.OpenWrite(fileName);
    outStream.Write(resultHtmlAsBytes, 0, resultHtmlAsBytes.Length);
}
