NetsuShelf

NetsuShelf is a browser extension for Chrome and Firefox that converts supported web novels and story pages into offline reading files.

It is a maintained fork of WebToEpub, with NetsuShelf-specific packaging, branding, UI updates, and store submission work.

Features

• Export supported stories to EPUB, HTML, PDF, or TXT
• Detect title, author, cover, and chapter list from supported pages
• Choose a chapter range before export
• Type chapter numbers directly in the chapter range inputs
• Edit metadata such as title, author, language, filename, and cover image
• Keep optional local library entries in browser storage for later updates
• Work across many supported sites through built-in site parsers and the default parser

Installation

Chrome

1. Download the latest NetsuShelf.chrome.*.zip asset from GitHub Releases.
2. Extract the archive.
3. Open chrome://extensions/.
4. Enable Developer mode.
5. Click Load unpacked and select the extracted plugin/ directory.

Firefox

1. Download the latest NetsuShelf.firefox.*.zip asset from GitHub Releases.
2. Rename the file to .xpi if you want to install it directly as an add-on package.
3. Open about:debugging#/runtime/this-firefox for temporary loading, or install the packaged add-on through Firefox if you are distributing a signed build.

From source

npm install
npm run lint

Packaged outputs are written by the build tooling into eslint/.

Usage

NetsuShelf works best when opened on a supported series page, table of contents page, or any story page that exposes the chapter list.

1. Open a supported story page.
2. Click the NetsuShelf extension icon.
3. Wait for NetsuShelf to analyze the page and load metadata and chapters.
4. Check the detected title, author, cover, and chapter list.
5. Choose the first and last chapter you want.
6. If useful, type chapter numbers directly into the No. inputs.
7. Choose the output format and click the export button.

On some sites, starting from the first chapter also works when the parser can discover the remaining chapters from there.
