I need to convert PDF files to Images. If the PDF is Multi-page,I just need one image that contains all of the PDF pages.
Are there any open source solutions which are not charged like the Acrobat product?

The following thread is suitable for your request.converting pdf file to an jpeg image
One solution is to use a third party library. ImageMagick is a very popular, freely available too. You can get a .NET wrapper for it here. The original ImageMagick download page is here.

If you use this process to convert a PDF to tiff, you can use this class to retrieve the bitmap from tiff.
Use it like so:

You can use Ghostscript to convert PDF to images.
To use Ghostscript from .NET you can take a look at Ghostscript.NET library (managed wrapper around the Ghostscript library).

To produce image from the PDF by using Ghostscript.NET, take a look at RasterizerSample.

As for 2018 still no simple answer on the question how to convert PDF to image in C#; many libs use GhostScript licensed under AGPL and in most cases expensive commercial license is required for production use.
Good alternative might be using poppler 'pdftoppm' utility which has GPL license; it can be used from C# as command line tool executed with System.Diagnostics.Process. Poppler tools are well known in Linux world, but windows build is also available.
If you don't want to integrate pdftoppm by yourself you can use my PdfRenderer poppler wrapper (supports both classic .NET Framework and .NET Core) - it is not free but pricing is very affordable.

The PDF engine used in Google Chrome, called PDFium, is open source under the 'BSD 3-clause' license. I believe this allows redistribution when used in a commercial product.
There is a .NET wrapper for it called PdfiumViewer (nuget) which works well to the extent I have tried it. It is under the Apache license which also allows redistribution.

(Note that this is NOT the same 'wrapper' as https://pdfium.patagames.com/ which requires a commercial license).
(There is one other PDFium .NET wrapper, PDFiumSharp, but I have not evaluated it.)
IMO so far, this may be the best choice of open-source (free as in beer) PDF libraries to do the job which do NOT put restrictions on the closed-source / commercial nature of the software utilizing them. I don't think anything else in the answers here satisfy that criteria, to the best of my knowledge.

This nuget package:https://www.nuget.org/packages/Pdf2Png/
is available for free and is only protected by the MIT license, which is very open.
I've tested around a bit and this is the code to get it to convert a pdf to an image. (It does save the image in the debug folder).

Use tanPDF. It's accurate, and a fraction of the price of Ghostscript for commercial use. And of ImageMagick too, since that requires Ghostscript.
Keep iTunes up-to-date Ensure that you have the latest iTunes software version installed on your computer before plugging in your iPhone. ITunes should automatically check this when it is run, but you can also force an update check by clicking the Help menu and choosing Check for Updates (Mac: click the iTunes menu tab, followed by Check for Updates). Download free songs to computer.
tanPDF uses Skia, so if you would like one image containing all pages, draw each page's SKImage onto an SKCanvas.

You could use Super Pdf2Image Converter to generate a TIFF multi-page file with all the rendered pages from the PDF in high resolution. It's available for both 32 and 64 bit and is very cheap and effective. I'd recommend you to try it.
Just one line of code..

Would you like to answer one of these unanswered questions instead? Not the answer you're looking for? Browse other questions tagged c#imagepdf or ask your own question.In this code example, we will provide a standalone Java class which will convert a PNG image to a PDF document, by using the iText Java API. This example is on the same lines as our BMP to PDF Conversion tutorial. The difference lies in the class used to read the input PNG image file. We will use the class com.itextpdf.text.pdf.codec.PngImage to accept a PNG image and return an object of type com.itextpdf.text.Image, so that we can add it to the PDF document directly. Note that this example requires a basic understanding of iText, and if you are new to iText, then I would suggest using the search functionality on this blog to find some beginners tutorials on iText. As such the code to convert PNG to PDF is very straightforward, and you can follow it quite easily, if you know some Java basics. The commented version of the Java code for this example is provided below;Itextsharp Convert Pdf To TiffThis example accepts a test image file and converts it to PDF.
