3. Convert PDF Files to PNG images
The process of converting PDF documents into PNG images is made remarkably straightforward through the utilization of the IronPDF .NET library. Within this segment, we will delve into the streamlined methodology that enables you to seamlessly transform PDFs into PNG images with a mere handful of concise code lines. By harnessing the capabilities of IronPDF, this process becomes an efficient and accessible endeavor. Let's navigate through the steps that empower you to achieve this conversion effortlessly.
3.1. Input PDF files
A three-page PDF document with a variety of graphs and charts
using IronPdf;
// Load the PDF document you want to convert
var pdf = PdfDocument.FromFile("bucket.pdf");
// Convert each page of the PDF into a separate PNG image stored in the specified directory
pdf.RasterizeToImageFiles(@"C:\image\folder\*.png");
using IronPdf;
// Load the PDF document you want to convert
var pdf = PdfDocument.FromFile("bucket.pdf");
// Convert each page of the PDF into a separate PNG image stored in the specified directory
pdf.RasterizeToImageFiles(@"C:\image\folder\*.png");
Imports IronPdf
' Load the PDF document you want to convert
Private pdf = PdfDocument.FromFile("bucket.pdf")
' Convert each page of the PDF into a separate PNG image stored in the specified directory
pdf.RasterizeToImageFiles("C:\image\folder\*.png")
The above code uses the IronPDF library in a .NET application to convert all pages of a specified PDF file ("bucket.pdf") into a series of PNG files. The FromFile
method loads the PDF, and then each page is converted to PNG format. The RasterizeToImageFiles
method specifies the output directory and file format, automatically naming files based on input content and producing high-quality PNG images.
3.2. Output Images
Three PNG pictures in the Windows file explorer, one for each of the PDF pages
