If an open source solution is not viable, you can check out the leadtools sdk which will handle this for you : https://www.leadtools.com/support/forum/posts/t13846-HOW-TO--Use-LEADTOOLS-to-convert-images-and-documents-to-a-PDF-file

Hi Narasingh

Add the reference of itextsharp.dll from the Nugate packages
private void button7_Click(object sender, EventArgs e)
       {

           ConvertImageToPdf("D://lotous.jpg", "D://lotous.pdf");
       }



       public static void ConvertImageToPdf(string srcFilename, string dstFilename)
       {
           iTextSharp.text.Rectangle pageSize = null;

           using (var srcImage = new Bitmap(srcFilename))
           {
               pageSize = new iTextSharp.text.Rectangle(0, 0, srcImage.Width, srcImage.Height);
           }
           using (var ms = new MemoryStream())
           {
               var document = new iTextSharp.text.Document(pageSize, 0, 0, 0, 0);
               iTextSharp.text.pdf.PdfWriter.GetInstance(document, ms).SetFullCompression();
               document.Open();
               var image = iTextSharp.text.Image.GetInstance(srcFilename);
               document.Add(image);
               document.Close();

               File.WriteAllBytes(dstFilename, ms.ToArray());
           }
       }

You can use the library I wrote, it's MIT and in C#.
You can see the source code at https://github.com/FairfieldTekLLC/Hocr

There is a good portion of posts on the internet about performing Optical Character Recognition (OCR).
There many free OCR engines that you can use like MODI, GOCR, Akshara Malayalam and Tesseract.
I implement an OCR engine from leadtools in my application but I was able to do a quick search and find many samples on how to use Tesseract OCR engine. Here is the link:

And you can find more information about Tesseract here:
