Active2 months ago
Nov 23, 2011 Hi guys, anybody knows how to convert pdf files to image format (jpeg or png) via C#, it's not extract images from pdf, If you know that please give me some help. I want to add a new image to exist PDF, and not new PDF. I try to use iTextSharp.dll, and I found it was create new PDF and add image, but I want to add image to exist PDF and not create new PDF. You can extract Image from PDF and save as JPG here is the sample code you need Itext Sharp. Public IEnumerable ExtractImagesFromPDF(string sourcePdf) // NOTE: This will only get the first image it finds per page. Next is to convert the PDF document generated by ItextSharp to an image with Spire.Pdf. Open the PDF document. To open a document the Spire.PDF library contains a PdfDocument class, that allows loading PDF documents in many formats, stream, byte, and so on.
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.

And you also can take a look at this thread:how to open a page from a pdf file in pictureBox in C#
If you use this process to convert a PDF to tiff, you can use this class to retrieve the bitmap from tiff. Sako rifle serial number lookup.
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.
To combine multiple images into the single image, check out this sample: http://www.niteshluharuka.com/2012/08/combine-several-images-to-form-a-single-image-using-c/#

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.
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..

iText/iTextSharp can generate and/or modify existing PDFs but they do not perform any rendering which is what you are looking for. I would recommend checking out Ghostscript or some other library that knows how to actually render a PDF.

You can use Ghostscript to convert the PDF files into Images, I used the following parameters to convert the needed PDF into tiff image with multiple frames :
Also you can use the -q parameter for silent modeYou can get more information about its output devices from here Coreldraw 2018 keygen x force 1.
After that I can easily load the tiff frames like the following
