PDFBook — read, create, extract & organize your PDF library

PDFBook is a desktop app for reading and managing large PDF collections — books, papers, manuals, manga, and scans — on Windows, macOS, and Linux. It runs entirely on your computer: no account is needed to read, and your library never leaves your device.

Features

A reader built for long sessions

Page-flip and vertical-scroll modes, right-to-left (manga) reading, in-document text search, bookmarks, zoom, and reading-position memory that reopens each book where you left off. Password-protected PDFs and a distraction-free focus mode are supported. See the reader guide.

A library that stays organized

Point PDFBook at folders of PDFs and it keeps your catalog in sync. Sort and filter by tags, ratings, favorites, and reading status, add notes per book, and browse covers in grid or list view. See the library guide.

Create and extract PDFs

Build a PDF from images or pages, convert other document formats, and pull selected pages out into a new file — all locally. See creating PDFs.

Capture pages from the screen

Turn pages shown in another app into a PDF, with automatic page-turning on Windows. See screen capture.

Optional AI assistant

Ask questions about the page you're reading, using a provider you choose — Ollama (local), OpenAI, Claude, or OpenRouter. See the AI assistant guide.

Private and offline

No account is required to read, and everything is processed on your machine. PDFBook works fully offline.

About this repository

This repository holds two things:

1. The documentation site — source for https://wiki.pdfbook.app, built with Astro Starlight and deployed on Vercel (zero-config: Vercel detects Astro, runs astro build, serves dist).
2. Release downloads — installers for every platform are published to this repository's Releases.

Working on the docs

npm install
npm run dev      # local preview at http://localhost:4321
npm run build    # production build into ./dist

Pages live in src/content/docs/ — English at the root, Japanese under ja/. A page with no Japanese translation falls back to English automatically.
