using (var document = new PdfDocument())
{
PdfPage page = document.AddPage();
using (XImage img = XImage.FromFile(imageFileName))
{
// Calculate new height to keep image ratio
var height = (int)(((double)width / (double)img.PixelWidth) * img.PixelHeight);
// Change PDF Page size to match image
page.Width = width;
page.Height = height;
XGraphics gfx = XGraphics.FromPdfPage(page);
gfx.DrawImage(img, 0, 0, width, height);
}
document.Save(pdfFileName);
}
if (deleteImage)
File.Delete(imageFileName);

The most easy way to convert image to pdf is to use GroupDocs.Conversion for .NET API. Its implementation is quite simple. All you need to do is to refer a single DLL in your existing or new proejct and write following code:
// Setup Conversion configuration and Initailize ConversionHandler
ConversionConfig config = new ConversionConfig();
config.StoragePath = "source file storage path";
// Initailize ConversionHandler
ConversionHandler conversionHandler = new ConversionHandler(config);
// Convert and save converted document
var convertedDocumentPath = conversionHandler.Convert("sample.png", new PdfSaveOptions{  });
convertedDocumentPath.Save("result-" + Path.GetFileNameWithoutExtension("sample.png") + ".pdf");
While converting image to pdf you can implement a lot of features like:
Add watermark
Page rotation
Measure conversion time

Download and evaluate open-source example project https://github.com/groupdocs-conversion/GroupDocs.Conversion-for-.NET

You can use the HTML5/JS Document viewer with the .NET Document conversion services from LEADTOOLS in your MVC Web application to convert images into PDF format, and then view them.
For example, the following server side code shows how you can convert a TIFF image into PDF document using the Document converter class:
byte[] ImageByteArray = File.ReadAllBytes("Input.tif");
using (MemoryStream ms = new MemoryStream(ImageByteArray))
{
   ms.Seek(0, SeekOrigin.Begin);
   ms.Position = 0;
   var options = new LoadDocumentOptions();
   using (var document = DocumentFactory.LoadFromStream(ms, options))
   {
      using (DocumentConverter documentConverter = new DocumentConverter())
      {
         var outFile = @"outFile.pdf";
         var format = DocumentFormat.Pdf;
         var jobData = DocumentConverterJobs.CreateJobData(document, outFile, format);
         jobData.JobName = "conversion job";
         var job = documentConverter.Jobs.CreateJob(jobData);
         documentConverter.Jobs.RunJob(job);
      }
   }
}
After this, you can view the result PDF file using the web document viewer control as shown in the following thread:
