Common questions

What is a DjVu file?
DjVu (.djvu) is a document format made for scanned books, manuals, and journals. It keeps scans sharp while staying much smaller than an equivalent PDF. Niraqua opens these files natively on your Mac, iPhone, and iPad.
Can Niraqua convert DjVu to PDF?
Yes. Open any .djvu document and export it to a clean PDF, with a quality preset and an optional searchable text layer.
Can I search and select text in scanned documents?
Yes. Niraqua finds and copies existing text, and its on-device text recognition (OCR) makes scanned pages searchable too.
Does Niraqua send my documents anywhere?
No. There is no tracking, no account, and no network upload. Your files and any recognized text are processed entirely on your device.
What do I need to run Niraqua DjVu?
A Mac running macOS 14 Sonoma or later, or an iPhone or iPad running iOS 26 or later. The app is a one-time purchase on the App Store, shared across all your devices.
Is there an iPhone or iPad version?
Yes. Niraqua DjVu is a universal purchase: buy it once and use it on Mac, iPhone, and iPad. The iOS app opens the same documents with reading, search, on-device text recognition, and PDF export - see the iPhone and iPad page in the help.
