How to Extract PDF Pages via Node.js SDK

In order to Extract Pages from PDF, we’ll use Aspose.PDF Cloud Node.js SDK. This Cloud SDK assists Node.js programmers in developing cloud-based PDF creator, annotator, editor, and converter apps using Node.js programming language via Aspose.PDF REST API. Simply create an account at Aspose for Cloud and get your application information. Once you have the App SID & key, you are ready to give the Aspose.PDF Cloud Node.js SDK.

Steps to Extract Pages via Cloud Node.js

Aspose.PDF Cloud developers can easily Extract Pages from PDF in just a few lines of code.

  1. Create an object to connect to the Pdf.Cloud API
  2. Upload your document file
  3. Downloads the modified PDF document
  4. Retrieves information about all pages in the PDF
  5. Retrieves information about a specific page
  6. Displays information about the pages in the console

    import credentials from "./credentials.json"  with { type: "json" };
    import fs from 'node:fs/promises';
    import path from 'node:path';

        PAGE_NUMBER: 2,     // Your document page number...
    };

    const pdfApi = new PdfApi(credentials.id, credentials.key);

    async function main() {

Work with the Pages in PDF via Node.js SDK

Extracting pages from a PDF is a common task that serves various purposes across different contexts. This process involves selecting specific pages from a larger document to create a new, separate PDF file. Understanding the reasons behind this practice can help in effectively managing and utilizing PDF documents.​ Large PDF files can be cumbersome to share or store. By extracting only the necessary pages, users can create smaller, more manageable files. This is particularly useful when only a portion of the document is relevant for a specific purpose. For instance, removing unnecessary pages can significantly decrease the file size, making it easier to handle and distribute. ​ Extracting pages allows users to repurpose content for different applications. For example, one might extract pages from a comprehensive report to create a standalone summary or to isolate specific data for analysis. This enables the reuse of existing content without the need to recreate information from scratch. Extract the Pages from PDF documents with Aspose.PDF Cloud Node.js SDK.
