## What it is
A Chrome and Firefox browser extension that downloads borrowable books from Internet Archive (archive.org) and full-view books from HathiTrust as PDFs or image collections. It fetches each leaf of a book and streams a PDF to disk on the fly, handling books with thousands of pages using little memory.

## Use cases
- download borrowed archive.org books as pdf
- save hathitrust full-view books offline
- export internet archive book as images
- download book with embedded searchable text
- download multiple books in parallel from archive.org

## When to choose
- you have borrowing access on archive.org or full-view access on hathitrust and want offline PDF copies
- you need large books downloaded with low memory usage
- you want per-page image exports instead of a single PDF

## When to avoid
- you do not have borrowing or full-view permissions for the book
- you need a general-purpose web scraper rather than a book downloader
- you use a browser other than Chrome, Edge, Brave, Vivaldi, or Firefox
