How to open DjVu files on iPhone and iPad

Updated October 15, 20262 min read

iPhone and iPad can't open DjVu files on their own: the Files app only shows a blank icon, and Apple Books doesn't support them. Here's how to open any .djvu file in three simple steps, for free.

Step 1

Install DjVu Reader (free)

Download DjVu Reader from the App Store on your iPhone or iPad. It's free, and it comes with a sample book so you can try it straight away.

Step 2

Add your DjVu file

Bring your book in whichever way is easiest:

From the Files app (iCloud Drive, On My iPhone, Dropbox, Google Drive): open DjVu Reader, tap + in Library and pick your file.
From Safari, Mail, Telegram or WhatsApp: tap the .djvu file, tap the Share button, then choose DjVu Reader.
From your computer: in DjVu Reader, open Settings › Wi‑Fi Transfer and drop the file onto the page it shows in your computer's browser.

Step 3

Start reading

A book shared from another app opens right away; one added from Files waits in the Library, so just tap it. Turn pages with a swipe or a tap on the edge, pinch to zoom, change the page colour, search the book or have it read aloud.

Why doesn't my iPhone open DjVu files?

DjVu is a format for scanned books that Apple doesn't support. The Files app can store .djvu files but can't show them, and Apple Books only opens EPUB and PDF. You need an app that reads DjVu, such as DjVu Reader. More in DjVu vs PDF: what's the difference?
