Extract Images from PDF

As part of IronPDF's extensive collection of PDF creation and editing functions, IronPDF also facilitates granular processing of a PDF document's content through its content extraction methods.

The extractAllImages method returns a collection of all the images embedded in a PDF document, each formatted as a BufferedImage object.

The most common business use case is to save PDF images in separate files. The featured code example below demonstrates a method to achieve this using the extractAllImages method along with the Java ImageIO class.

IronPDF can also pull images from PDFs in their raw byte form. For this, use the extractAllRawImages method instead.

It is also possible to extract images from a subset of PDF pages (as opposed to the entire document). The brief code snippet below uses the extractAllImagesFromPages method to pull the images from pages 3 and 7 of a sample document.

import com.example.IronPdfLibrary; // Example import, the actual library path may differ depending on your setup
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.nio.file.Paths;
import java.util.List;
import javax.imageio.ImageIO;

public class PdfImageExtractor {
    public static void main(String[] args) {
        try {
            // Load the PDF document from a file
            PdfDocument document = PdfDocument.fromFile(Paths.get("sample.pdf"));

            // Extract all images from pages 3 to 7
            List<BufferedImage> pageRangeImages = document.extractAllImagesFromPages(PageSelection.pageRange(3, 7));

            // Iterate through each extracted BufferedImage
            for (int i = 0; i < pageRangeImages.size(); i++) {
                BufferedImage image = pageRangeImages.get(i);

                // Save each extracted image as a separate file
                File outputfile = new File("extracted_image_" + i + ".png");
                ImageIO.write(image, "png", outputfile);
            }
        } catch (IOException e) {
            System.out.println("An error occurred while processing the PDF: " + e.getMessage());
        }
    }
}

            PdfDocument document = PdfDocument.fromFile(Paths.get("sample.pdf"));

            // Extract all images from pages 3 to 7
            List<BufferedImage> pageRangeImages = document.extractAllImagesFromPages(PageSelection.pageRange(3, 7));

            // Iterate through each extracted BufferedImage
            for (int i = 0; i < pageRangeImages.size(); i++) {
                BufferedImage image = pageRangeImages.get(i);

                // Save each extracted image as a separate file
                File outputfile = new File("extracted_image_" + i + ".png");
                ImageIO.write(image, "png", outputfile);
            }
        } catch (IOException e) {
            System.out.println("An error occurred while processing the PDF: " + e.getMessage());

How to Extract Images from PDF in Java

1. Install IronPDF Java Library
2. Use the extractAllImages method to extract images from a PDF
3. Iterate through each image in the images collection object
4. Export the extracted images with the write method in Java
5. Perform the extraction without affecting the original PDF
