is right that a purpose-built PDF renderer will handle this; ABCpdf is distributed by WebSupergoo (search for "WebSupergoo ABCpdf" to find the vendor page and a trial). If a commercial component isn’t an option, a common free approach is to use Ghostscript (native executable) with a .NET wrapper such as Ghostscript.NET to rasterize the first page and then resize it to a thumbnail.

Example workflow (produce a PNG of page 1, then make a thumbnail). Install Ghostscript on the server, add a Ghostscript.NET reference, then:

using Ghostscript.NET.Rasterizer;
using System.Drawing;
using System.Drawing.Imaging;

string pdfPath = @"C:\temp\doc.pdf";
string firstPagePng = @"C:\temp\firstpage.png";
int dpi = 150;

using (var rasterizer = new GhostscriptRasterizer())
{
    rasterizer.Open(pdfPath);
    using (var img = rasterizer.GetPage(dpi, 1)) // page numbers start at 1
    {
        img.Save(firstPagePng, ImageFormat.Png);
    }
}

Resize to a good-quality thumbnail (high-quality interpolation):

using System.Drawing.Drawing2D;

Image Resize(Image src, int width)
{
    int height = (int)(src.Height * (width / (double)src.Width));
    var thumb = new Bitmap(width, height);
    using (var g = Graphics.FromImage(thumb))
    {
        g.InterpolationMode = InterpolationMode.HighQualityBicubic;
        g.CompositingQuality = CompositingQuality.HighQuality;
        g.SmoothingMode = SmoothingMode.HighQuality;
        g.DrawImage(src, 0, 0, width, height);
    }
    return thumb;
}

Notes and troubleshooting: Ghostscript must be installed and the native binary's bitness should match the process. If images are black/blank, check Ghostscript availability, permission to execute it, and whether the PDF is encrypted. System.Drawing on ASP.NET has concurrency and platform caveats—on modern stacks prefer SkiaSharp or ImageSharp. For production/scale, generate thumbnails asynchronously on upload and cache them. Commercial alternatives (ABCpdf, Aspose.PDF) can simplify this if licensing is acceptable.

ABCpdf Professional will do this for you. It's a component for generating and manipulating PDF documents server-side from within ASP.NET and features a built-in image renderer.

You may notice Visual Studio display a dialog when you add ABCpdf as a reference. It'll warn you the component uses a higher version of the .NET framework than your project. ABCpdf makes use of frameworks newer than version 2.0, but only if they're available. So, you can safely ignore the warning and add it to your project.

The documentation includes example code written in csharp.
