Archive.org Book Downloader

📖 Introduction ═══════════════════════════════════════ Archive.org Book Downloader is a browser extension designed specifically for the Archive.org library. It automatically parses book pages, batch downloads high-quality images, and converts them to PDF, ZIP, or CBZ formats for offline reading and collection. ═══════════════════════════════════════ ✨ Features ═══════════════════════════════════════ 🚀 Auto Parsing — One-click parsing of Archive.org book pages, automatically retrieving all page information. 📥 Batch Download — Batch download book images, automatically converted to JPEG (quality 1.0, highest quality). 🔐 Image Decryption — Automatically handles Archive.org's image obfuscation / encryption. 💾 Local Storage — Store images using IndexedDB, with resume-from-breakpoint support. 📄 Multi-format Export — Export to PDF, ZIP, or CBZ formats. 🎯 Selective Download — Select specific pages to download or export. 🖼️ Image Preview — Preview images before downloading. 🔄 Drag & Sort — Drag-and-drop to adjust page order. 🌍 Multi-language Support — Automatically adapts to the browser language (Chinese / English). 🎨 Manual Capture Mode — Page-by-page capture for scenarios requiring precise control. ═══════════════════════════════════════ 🚀 Usage ═══════════════════════════════════════ 📌 Prerequisites (Read First) ─────────────────────────────────────── Before starting, please confirm the following three points to avoid parsing failures or interrupted downloads: 1. 🔌 Keep the Extension Popup Active • The entire process of parsing, downloading, and generating PDF / ZIP / CBZ requires the extension popup to remain open. • The Chrome extension popup is a system-level overlay — it closes automatically when you click on the browser page or switch to another window. • Once the popup closes, the ongoing download and parsing tasks are immediately interrupted. • Already downloaded images are persisted in the local IndexedDB (no data loss) — next time you click the extension icon, downloading can resume from the breakpoint. • Tip: During parsing, do not click elsewhere on the page and do not switch windows — patiently wait for the progress to complete. 2. 🔑 Borrow the Book (For Restricted Content) • If the target book is marked as "Borrow" or "Log In And Borrow", you must borrow it first to download the full content: 1) Log in with your Archive.org account; if you don't have one, sign up for free at: https://archive.org/account/signup 2) Click the "Borrow" button on the book details page to complete borrowing. 3) Wait for the BookReader to load the complete book content (you should be able to flip through pages normally). 4) Then click the extension icon and use this plugin to parse and download. • Note: Forcing parsing without borrowing often retrieves only the cover or preview pages, and the images may be encrypted and undecryptable. 3. 📖 Ensure BookReader Has Fully Loaded • After entering the book details page, wait for the BookReader to fully load (page-turning works normally). • Then click the extension icon to start parsing, to prevent page information extraction failure due to an unready page. ─────────────────────────────────────── Method 1: Auto Parsing (Recommended) ─────────────────────────────────────── 1. Open Book Page • Visit an Archive.org book details page, for example: https://archive.org/details/isbn_9780440842897 2. Start Parsing • Click the extension icon in the Chrome toolbar. • Click the "Scan Current Book" button. • Wait for automatic parsing and downloading to complete. 3. Generate Files • After parsing, select the desired pages (or select all). • Click the "Generate PDF", "Download ZIP", or "Download CBZ" button. • Choose the save location and complete the download. ─────────────────────────────────────── Method 2: Manual Capture Mode ─────────────────────────────────────── ⚠️ Important: Before using manual capture, please make sure to: 1) Switch to single-page reading mode on Archive.org (click the single-page icon on the page). 2) Navigate the book to the first page (starting page). 3) Then click the "Manual Scan" button. 1. Preparation • Visit the Archive.org book details page. • Switch to single-page reading mode. • Ensure the first page is currently displayed. 2. Start Capture • Click the extension icon. • Click the "Manual Scan" button. • The extension will automatically flip through pages and capture images. 3. Complete Download • After capture is complete, follow step 3 of Method 1 to generate files. ─────────────────────────────────────── Other Features ─────────────────────────────────────── • Image Preview: Click any image for a full-screen preview. • Select Pages: Use the "Select All", "Invert Selection", and "Clear Selection" buttons. • Delete Images: Select images and click "Delete Selected". • Drag & Sort: Directly drag images to adjust their order. • Clear Data: Click the "Clear" button to remove all local data. ═══════════════════════════════════════
