BookFolder-Books Comics Novels

Your files. Your bookshelf. Your way to read.

BookFolder organizes books, comics, novels, images and PDFs in a folder-based library. Read pages, customize text or listen with text-to-speech. Use files on your device or your own server.

IMAGES, COMICS AND PDFS
Open JPG and PNG images, image folders, ZIP and CBZ comic archives, and PDFs.
• Single-page and two-page views
• Half-page viewing for wide images
• Pinch to zoom from 1x to 5x
• Drag to explore enlarged pages
• Turn pages with taps or swipes
• Bookmarks and quick page navigation

View the whole page or zoom into details. Half-page mode divides wide pages and saves the section you were reading.

DISPLAY SETTINGS FOR YOUR READING SPACE
Smart margin removal reduces blank white or black borders around images. Detection is conservative: uncertain borders are retained, so results vary by page.
• Automatic rotation or fixed orientation
• Single or double pages in portrait view
• Brightness and color filters
• Page-effect strength and shadows
• Screen timeout and control-bar hiding
• PDF quality and processing options

Some advanced display options require PRO. Margin removal trims source-image borders; it does not guarantee that every page fills every screen.

NOVELS AND EBOOKS
Open EPUB, TXT and DOCX documents and adapt the text to your reading preferences.
• Text size and font selection
• Line spacing and page margins
• Reading backgrounds and display settings
• Search and table-of-contents navigation
• Bookmarks and saved reading positions

Enlarge text on a phone or use a wider layout on a larger screen. Search for passages or navigate available chapters. Layout and chapter navigation depend on document structure.

READ OR LISTEN
Listen to text documents using TTS, adjust reading speed and voice settings, and follow highlighted text with automatic page changes during playback.

Read-aloud features require readable text. They do not automatically recognize lettering in images or scanned PDFs. Voices, languages and pronunciation depend on your installed TTS engine and voice data. Advanced narration features require PRO.

A LIBRARY BUILT AROUND YOUR FOLDERS
Add files and folders from your device, import multiple files and browse subfolders. Use an existing arrangement by author, series or genre.
• Search books and folders
• Check reading progress
• Resume saved reading positions
• Return to bookmarks and navigate quickly
• Choose white or black themes

BOOKFOLDER PRO
Start with free reading features and unlock advanced options with a one-time in-app purchase:
• Enhanced page-turning effects
• Continuous webtoon viewing and vertical scrolling
• Portrait one-handed mode
• Image remastering
• Advanced novel layouts and narration
• Performance-priority PDF mode
• Additional themes and a private bookshelf
• FTP, SMB and WebDAV connections
• Server streaming, downloads and caching

Webtoon mode joins images vertically and supports dragging and inertial scrolling. Saved choices and vertical positions let you continue each book later. Image remastering adjusts page appearance; results depend on the source.

YOUR OWN SERVER
Connect to a configured NAS or personal server with PRO. Browse, stream or download files, and place server-book shortcuts in your library. You provide the server and connection details. Availability and speed depend on your network, server and files; cloud storage is not included.

PURCHASES, LANGUAGES AND SUPPORT
PRO is a one-time purchase, not a subscription. Google Play handles pricing and payment. Restore valid purchases with the same Google Play account.

The interface supports Korean, English, Japanese, Simplified Chinese and Spanish. This does not translate your books.

BookFolder reads your own files; books and comics are not included. Local files can be read on your device. Server access, downloads and some voice setups need a network. Compatibility and performance vary by document and device. For help, use the support email on this listing.
