NurViewer 600+ Formats: EPUB/PDF/CAJ/PDG, Read ZIPs, Notes, OCR, Dicts, PDF-to-Word

[NurViewer]

Hello everyone!

I'm a member of the **NURSOVA software development team**, and we'd like to introduce **NurViewer**, our versatile file viewer and reading application for Windows.

NurViewer supports **600+ file types and extensions**, bringing e-book reading, document viewing, dictionary lookup, annotations, OCR, conversion, and media playback into one application.

Here are some features that may interest MobileRead members:

**1. E-book Reading**

Supports EPUB, PDF, CAJ, PDG, DjVu, MOBI, AZW3, FB2, CHM, CBZ, CBR, and many other formats, including supported complex EPUB layouts, vertical Chinese/Japanese text, and scanned books.



**2. Rich Reading Notes**

Create long-form notes linked to specific locations in EPUB and PDF documents. Notes can contain text, images, tables, and detailed explanations. Standard PDF annotations and Markdown note export are also supported.

**3. Local Dictionaries & Vocabulary**

Look up words directly while reading using MDict, StarDict, DSL, XDXF, EPWING, and other supported dictionaries. Save vocabulary with context and export word lists to CSV/TSV or, in eligible editions, Anki.

**4. Read Books Without Extracting Archives**

Open supported books directly inside ZIP, RAR, 7z, and other archives. A built-in password vault can remember saved passwords for supported encrypted archives. ISO and other supported containers can also be browsed.

**5. OCR & Document Conversion**

Whole-page and selected-area OCR, searchable PDFs, table recognition, PDF-to-Word/PowerPoint, EPUB-to-PDF, and other supported conversions.

**6. Subtitle-Based Language Learning**

Display and search available video subtitles, jump to specific lines, look up words using local dictionaries, adjust playback speed, and repeat selected passages with A–B looping.

### Free Edition — No Trial Expiration

**Many everyday features remain permanently free. NurViewer's Free edition has no trial expiration.**

Common-format reading, ordinary PDF annotations, and supported ordinary document/image-to-PDF conversion remain available without a time limit.

Advanced processing and specialist formats have certain daily allowances or edition restrictions. Optional Standard and Pro editions are available as one-time purchases.

### We'd Love Your Feedback!

We're especially interested in feedback from MobileRead members about complex EPUB layouts, PDF annotations, uncommon e-book formats, local dictionaries, and reading workflows.

We'd be happy to answer questions, discuss technical details, and hear your suggestions.

Thank you for reading!
