# Niraqua

> Niraqua DjVu is a DjVu reader and PDF converter for Mac, iPhone, and iPad. It opens .djvu files, searches embedded or recognized text, supports contents and bookmarks, and exports all pages or selected pages to PDF. OCR and conversion run on the device.

The app is a one-time purchase for Mac, iPhone, and iPad. There is no subscription. Prices vary by App Store storefront and can change at any time. Use the App Store listing for the current price: https://apps.apple.com/app/niraqua-djvu/id6761933635

Requirements: macOS 14 Sonoma or later, iOS 26 or later, or iPadOS 26 or later. Support: support@niraqua.com.

The app has no account, analytics, or document upload service. The website separately offers optional, consent-based analytics; see Website privacy. User-selected cloud storage and sharing services have their own behavior.

Every published content page has a Markdown representation, including all 15 languages. Replace the HTML page's trailing slash with .md; the site root uses /index.md. Each document identifies its canonical HTML source. Language versions are self-canonical; the English links below are a starting point, not a preferred canonical for translations.
