PDF Extract Image

This is a Node.js library for extracting images from PDF files. It uses pdfjs-dist for reading PDF files and pngjs for encoding the extracted images as PNG files.

This is library did not render the PDF file to image, it only extracts the images from the PDF file. So the pdf file must contain images. Otherwise, it will return an empty array.

Installation

You can install this library using npm:

npm install pdf-extract-image

Usage

Here's a basic example of how to use this library:

import { extractImagesFromPdf } from 'pdf-extract-image';
import { writeFileSync } from 'fs';

async function main() {
  // const images = await extractImagesFromPdf(pdfBuffer);
  const images = await extractImagesFromPdf('/path/to/your.pdf');
  images.forEach((image, index) => {
    writeFileSync(`image${index}.png`, image);
  });
}

main().catch(console.error);

In this example, extractImagesFromPdf is used to extract images from a PDF file. The resulting images are then written to disk as PNG files.
