Hello MizunoX,
The resource you list is a interactive, online service: it needs an Internet connection and extensive interaction with the user. What this discussion looks for is a library to integrate in the code in order to perform the conversion without user interaction and any external resource.

The easiest way of converting a pdf to a jpeg is by using a reliable online service such as pdfjpg.net . All you need to do is upload the pdfs you would like to convert and download your newley converted jpegs.
Hope this helps Baki1492

Hey massonmilo,
I'm not too expericenced with PDF conversion tools in general, however it looks like there's a good amount of information available about this online, some of which I've added below. However, you should note that these webpages are not associated with or verified by NI.

I went hunting for a similar solution since I wanted to display portions of PDFs that were live generated by other software into a CVI app. I tried the ActiveX solution and didn't like it. It took me a while to find a solution to this, and it was harder to implement than I thought it should be. Now I have a solution that generates it all in memory, no command line app, no need to even save a file if you don't want to. I created the sample project attached here that renders the PDF into a Canvas control. It uses a DLL that I found on GitHub based on MuPDF (https://github.com/dwaleke/mupdf-converter). There's not much functionality, but it does everything I need. The one problem is that it doesn't report the number of pages in the PDF and crashes if you request a page beyond what exists in the file. Hopefully this project is helpful to someone.

It is true that you can use many online PDF converters to convert PDF to JPEG format. However, there are always these or those limitations. So if you have PDF files in large file size, or you want to get the high-quality JPEG images, then you can use WidsMob ConvertPDF software.
Well, I find that it allows users to batch convert PDF to JPEG in high resolution easily. Moreover, you can extract all images from PDF files by one click. Sounds quite good, right?
