Penguin Viewer: Manga Reader

Manga, webtoons, novels — even the ones no one translated. Penguin Viewer reads them all and translates on your device.

Penguin Viewer is a fast, private reader for the manga, comics, webtoons and novels you already own, with a translator built in that runs entirely on your device. Bring your own files, connect your NAS, and read on iPhone, iPad and Mac. No subscription, no ads, no account, just one optional lifetime purchase for Pro.

COMICS AND NOVELS IN ONE LIBRARY Drop in your collection and start reading in seconds.

• Opens CBZ, CBR, CB7, ZIP, RAR, PDF and image folders
• Reads TXT, MD and EPUB novels on the same shelf as your comics
• Drag and drop to import, and series are grouped automatically from ComicInfo metadata

A REAL NOVEL READER

• Set the font, text size, line spacing, margins and background in Text and Layout, and see every change as you make it
• Jump between chapters from the table of contents
• Your reading position and bookmarks carry over between devices
• See how long is left in the book, calculated from your own reading speed

TRANSLATION THAT STAYS ON YOUR DEVICE Reading something in a language you do not speak yet? Penguin Viewer recognizes the text and translates it where it sits.

• Manga: the translation lands right over the speech bubbles, vertical Japanese included
• Novels: translate a sentence or the whole page and read it beside the original, with dictionary lookups for single words
• Pre-translate a whole book so every page opens already translated
• Download language models ahead of time and translate offline
• Runs fully on device, so your pages are never sent anywhere

YOUR NAS IS YOUR LIBRARY Keep thousands of books on a server and read them anywhere.

• Connects over SMB, WebDAV and OPDS, and works with Komga and Kavita
• OPDS-PSE streaming reads page by page, no full downloads needed
• iCloud keeps your reading position in sync across iPhone, iPad and Mac

READING DONE RIGHT

• Single pages, smart two-page spreads, and true right-to-left for manga
• Keep spreads in landscape, switch to single pages in portrait
• Vertical scrolling for webtoons with hands-free auto-scroll, smooth at 120Hz, and pinch to zoom without leaving the strip
• Previous and next volume are one tap away while you read
• A draggable bottom page bar with thumbnails shows exactly where you are
• Auto Night Theme turns the reader black at the hour you choose
• Auto-crop scanned margins, bookmark any page, and fix shuffled pages with Page Order

A SHELF THAT KEEPS ITSELF TIDY

• Smart shelves file every book as Unread, Reading or Finished
• Multi-level sorting and instant search
• Set your own grid: column count, cover size, or just pinch to resize

MAKE READING A HABIT

• A reading calendar showing which days you read, and how much
• Home Screen and Lock Screen widgets on iOS
