How to Rasterize a PDF to Images

// Import the IronPdf library to work with PDF rendering and manipulation
using IronPdf;

// Instantiate a ChromePdfRenderer object to render PDFs with the Chrome rendering engine
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Render a PDF document from a specified web URL.
// The URL used here is Wikipedia's main page.
PdfDocument pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page");

// Export each page of the PDF as separate image files.
// The images will be saved with a naming pattern "wikipage_*.png",
// where the asterisk (*) will be replaced by the page number of each page in the PDF.
pdf.RasterizeToImageFiles("wikipage_*.png");
