Features

• Downloads manga from your Kindle library via read.amazon.co.jp and read.amazon.com.
• Extracts high quality images from the Kindle Renderer API.
• Packages downloads into ZIP, CBZ, and EPUB formats.
• Works as a Tampermonkey or Greasemonkey userscript.
• Full book support for text and glyphs is planned for a future release.

Requirements

• A Tampermonkey or Greasemonkey browser extension.
• An Amazon account with owned Kindle books.
• Access to the Kindle Web Reader at read.amazon.com or read.amazon.co.jp.
• You must own the books you wish to download, including titles marked "free to read for a limited time".

Installation

1. Install Tampermonkey or Greasemonkey in your browser.
2. Download kandle-downloader.js.
3. Open your Tampermonkey or Greasemonkey dashboard and import or drag in the .js file.
4. Navigate to read.amazon.com or read.amazon.co.jp and open a manga you own.
5. The downloader interface will appear, then select your desired output format and begin.

Usage

1. Open the Kindle Web Reader and navigate to a manga you own.
2. The script injects a download interface into the page.
3. Select your preferred format: ZIP, CBZ, or EPUB.
4. Start the download and let the script extract images and package them automatically.

Known Issues

1. If an image fails to download, the process continues and may produce an archive with missing or improperly numbered images.
2. RTL handling in EPUB may be incorrect and is likely a reader compatibility issue rather than a script bug.
3. Chapter names are present in the generated EPUB XML, but page indexes are currently incorrect.
