For Self-Scanned Books

A reader built foryour self-scanned book library.

PDFBook is a desktop PDF reader and library manager for Windows, macOS, and Linux, ideal for people who digitize physical books with a scanner like ScanSnap. Flip mode makes scanned pages feel like a real book with page-turn animation and sound. The built-in library organizes thousands of scanned volumes with folders, tags, and ratings. Password protection keeps sensitive scans private.

Flip mode for book-like reading

Scanned books are meant to be read as books. PDFBook's flip mode turns pages with animation and optional sound, recreating the physical reading experience from your digitized collection.

Manage thousands of scanned volumes

Folders, tags, star ratings, reading state, and per-book notes. Organize your scanned library by genre, author, or series. Thumbnail grid shows covers for visual browsing.

Handles large scan files

Scanned books produce large PDFs: 200 MB+ is common. PDFBook's dual engines use lazy, windowed rendering, so even the densest scans start showing pages quickly instead of loading the whole file up front.

Password protection per book

PDFBook supports password-protected PDFs and remembers passwords per book. Secure your personal scans without re-entering the password every time you open them.

Your files never leave your computer

Frequently asked questions

Can PDFBook handle large scanned PDF files?+
Yes. Scanned books often produce PDF files of 200 MB or more, and PDFBook handles them smoothly. Its dual rendering engines (pdf.js for flip mode, PDFium WASM for vertical scroll) are optimized for image-heavy PDFs. Users report fast opening even with scans from ScanSnap and other document scanners.
Does flip mode work well with scanned pages?+
Yes. PDFBook's flip mode is particularly satisfying with scanned books because the page-turn animation recreates the physical experience of the original book. Each scan is rendered as a full-page spread, and the optional flip sound adds to the tactile feel.
Can I password-protect my scanned book PDFs in PDFBook?+
PDFBook reads and manages password-protected PDFs: if your scanned book is already encrypted, PDFBook asks for the password once and remembers it for that specific book. The Creator can also add password protection to a PDF on your device, and the online Protect PDF tool on pdfbook.app does the same in your browser.
How do I organize a large scanned book collection?+
PDFBook's library supports folders (for hierarchical organization like Genre > Author > Series), tags (for cross-cutting labels like #favorite, #reference), star ratings (1-5), and reading state (Unread / Reading / Completed). You can also set watch paths so a launch or a manual Sync re-scans those folders and adds new scans to your library.
Is PDFBook better than reading scanned books in Adobe Acrobat?+
For reading and organizing scanned books, yes. Adobe Acrobat treats every PDF as a document to edit, while PDFBook treats them as a collection to manage and enjoy. Acrobat has no library, no tags, no flip mode with page-turn animation. PDFBook is purpose-built for the reading experience at $89 once versus Adobe's ongoing subscription (around $20/month as of June 2026).
