This guide covers installation, usage and code snippets for easy image extraction.

Why Extract Images from PDF?

  • Extract logos, infographics, and embedded photos from PDFs.
  • Automate document digitization for archiving and data processing.
  • Build custom PDF analyzers or image recognition pipelines.
  • REST API-based workflow — No need for desktop software.

In this article, we are going to cover following topics:

PDF Processing API

GroupDocs.Parser Cloud SDK for Node.js is a lightweight and easy-to-integrate API wrapper that allows developers to extract structured content—such as text, images, metadata, and document fields—from a wide variety of file formats including PDF, Word, Excel, and more.

Prerequisites Install the GroupDocs.Parser Cloud SDK for Node.js:

npm install groupdocs-parser-cloud

Create an account at the GroupDocs.Cloud Dashboard to obtain your Client ID and Client Secret for authentication. For further information, please visit this article.

Extract Images from PDF using Node.js

Follow these steps to develop your own image extractor from PDF using Node.js API:

Step 1: Set up Configuration.

const { ParserApi, Configuration, ImagesRequest, FileInfo, ImagesOptions } = require("groupdocs-parser-cloud");

const config = new Configuration("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");
const parserApi = new ParserApi(config);

Step 2: Define PDF File Info and Image Extraction Options. Initialize an object of the ImagesRequest class and pass the instance of the ImagesOptions class.

const fileInfo = new FileInfo();
fileInfo.filePath = "sample.pdf";

const options = new ImagesOptions();
options.fileInfo = fileInfo;

const request = new ImagesRequest(options);

Step 3: Extract Images. Invoke the images method to extract images from PDF file.

parserApi.images(request).then((response) => {
    console.log("Images extracted successfully.");
    console.log(response.images);
}).catch((err) => {
    console.error("Failed to extract images:", err);
});

You can see the output of the above code sample in the image below:

Extract Images from PDF via cURL

You can also extract images using GroupDocs.Parser REST API and cURL.

Step 1 – Generate Access Token:

curl -X POST "https://api.groupdocs.cloud/connect/token" \
-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
-H "Content-Type: application/x-www-form-urlencoded"

Step 2 – Extract Images via REST API:

curl -v -X POST "https://api.groupdocs.cloud/v1.0/parser/images" \
-H  "accept: application/json" \
-H  "authorization: Bearer {ACCESS_TOKEN}" \
-H  "Content-Type: application/json" \
-d "{  \"FileInfo\": {    \"FilePath\": \"Binder1.pdf\",    \"StorageName\": \"internal\"  },  \"OutputPath\": \"internal\",  \"StartPageNumber\": 1,  \"CountPagesToExtract\": 2}"
  • Replace <ACCESS_TOKEN> with the one you generated.
