How to convert PDF in Web Page In C#

The ParsePages method in the LEADTOOLS PDF SDK (https://www.leadtools.com/sdk/pdf) can be used to parse the objects in your PDF document and will return text items (characters), images, rectangles, annotations, form fields, digital signatures, hyperlinks and fonts as PDFObject structures which you can use to construct your webpage from the source PDF.

(Disclaimer: I am an employee of this toolkit’s vendor)

As an example, the following code parses a PDF file and finds form fields. For each field, it gives you the type (such as text box, check box, list box, combo box or radio button) and other information like location.

You can use this information to create similar controls in your HTML page.

using (PDFDocument document = new PDFDocument(pdfFileName))
{
PDFParsePagesOptions options = PDFParsePagesOptions.FormFields;
document.ParsePages(options, 1, -1);
foreach (PDFDocumentPage page in document.Pages)
{
Console.WriteLine("Page {0}", page.PageNumber);
IList formfields = page.PDFFormFields;
Console.WriteLine("No. of Form Fiels: {0}", fonts.Count);
foreach (PDFFormField formfield in formfields )
{
Console.WriteLine(" Name: {0}", formfield.Name);
Console.WriteLine(" Field Type: {0}", formfield.FieldType);
Console.WriteLine(" Bounds: ");
Console.WriteLine(" Left: {0}", formfield.Bounds.Left.ToString());
Console.WriteLine(" Top: {0}", formfield.Bounds.Top.ToString());
Console.WriteLine(" Width: {0}", formfield.Bounds.Width.ToString());
Console.WriteLine(" Height: {0}", formfield.Bounds.Height.ToString());
Console.WriteLine("------");
}
Console.WriteLine("---------------------");
}
}
