Html to pdf set margn issue

I am trying to set margin to my html to pdf document. but its not adding right margin. content also not showing fully.

        async Task<byte[]> ITransformHelper.ConvertHtmlToPdf(string htmlDocument, Manifest manifest, string header, string footer, string requestId)

<a class="attachment" href="/uploads/default/86449">image.png</a> (65.0 KB)

            string htmlFilePath = "";
            htmlFilePath = manifest.Output.OutputFileName?.Replace(".pdf", ".html"); 
            string modifiedHtml = htmlDocument.Replace("<body>", $"<body style='margin: 10px 20px 10px 30px;'>");
            File.WriteAllText(htmlFilePath, modifiedHtml); 

            var api = new HtmlApi("8bb39521-349d-415a-8712-8c6c8adb0b16", "31dab4a55d3ab3e2e1b89bdd8fd2d4f0").ConvertApi;
            var result = await api.ConvertAsync(htmlFilePath, manifest.Output.OutputFileName);

            // Load existing PDF document
            var pdfDocument = new Aspose.Pdf.Document(manifest.Output.OutputFileName);

            // Initialize HTMLLoadSave Options
            HtmlLoadOptions options = new HtmlLoadOptions();

            // Load HTML document using Aspose.Pdf.Document
            var doc = new Aspose.Pdf.Document(htmlFilePath, options);

            // Save the Aspose.Pdf.Document to PDF
            doc.Save(pdfDocument + "RenderContentToSamePage.pdf");

            byte[] fileBytes = File.ReadAllBytes(manifest.Output.OutputFileName);

            return fileBytes;

Looks like you are modifying the HTML string using Aspose.HTML and then generating Aspose.PDF to create PDF document out of it. You can achieve this entire functionality using Aspose.HTML.

For converting HTML to PDF and setting the PDF margins, you can use below code snippet:

Aspose.Html.Saving.PdfSaveOptions options = new Html.Saving.PdfSaveOptions()
    JpegQuality = 100,
options.PageSetup.AnyPage.Margin = new Html.Drawing.Margin(30);
options.PageSetup.AdjustToWidestPage = true;
options.BackgroundColor = System.Drawing.Color.White;
using (var document = new Aspose.Html.HTMLDocument(file))
    Aspose.Html.Converters.Converter.ConvertHTML(document, options, dataDir + "HTMLToPDFTest.pdf");
