This file archive utility unpacks Apple iWork documents (`.pages`, `.key`, and `.numbers`) directly inside your web browser without requiring a Mac, Apple ID, or iCloud subscription. Apple iWork saves documents as zipped package directories containing proprietary protobuf binary data, embedded image attachments, and a compiled, high-resolution QuickLook PDF preview.

### Internal iWork Archive Structure & Extraction Engine The extractor uses client-side JavaScript ZIP decompression (`JSZip`) to read the internal package hierarchy:

- **QuickLook PDF Preview Extraction:** When macOS and iOS save iWork files, they automatically compile an embedded visual preview: `preview.pdf`, `QuickLook/Preview.pdf`, or document root `*.pdf`. The tool locates this file, reads it as an array buffer, and mounts it into an in-browser PDF reader with download capabilities. - **Thumbnail Asset Extraction:** Searches for `QuickLook/Thumbnail.jpg` or `Data/thumbnail.png` to render instant visual covers of the document. - **Contained Files Manifest:** Displays a complete manifest of all bundled sub-files (including embedded photos, vector shapes, charts, and media clips).

### Concrete Extraction Workflow Example 1. **Input File:** Drag and drop an Apple Pages document `quarterly-report.pages` ($14\text{ MB}$). 2. **Decompression:** `JSZip` loads the archive in browser RAM within 200 milliseconds, locating `QuickLook/Preview.pdf` ($1.8\text{ MB}$). 3. **Preview & Export:** The PDF preview displays directly on screen. Clicking Download Extracted PDF allows Windows and Linux users to read, print, or convert the document without converting through third-party cloud servers.

### Privacy and Client-Side Decompression Guarantee All archive decompression and PDF extraction occur locally in your browser memory. No documents, confidential financial sheets, or presentation slides are uploaded across any network.
