If you build applications in ASP.NET, MVC, .NET Core, WebForms or Blazor, you already know the struggle: every project needs to display PDFs, preview Office files, open CAD drawings, or convert them into something users can actually work with. And most solutions require stitching together different libraries, viewers, plugins or installation-heavy components.
Doconut was created to end that headache.
It offers a universal server-side .NET document viewer and a powerful conversion engine, all wrapped in a clean integration experience that works across the entire .NET family. No client installs, no external plugins, no extra software. Just fast, accurate, pixel-perfect rendering directly inside your application.
Seamless in-app viewing with Doconut
Doconut makes document viewing feel native—on desktop, tablet, or mobile.
- Supports 50+ file types including PDF, DOCX, XLSX, PPTX, DWG/DXF, PNG/JPG, EML/MSG, HTML and more.
- Zero client-side installations — everything is rendered server-side for predictable quality.
- Responsive UI with RTL support, zoom, thumbnails, side-by-side mode, and two-page book view.
- Consistent rendering across browsers without depending on the client’s PDF reader or Office apps.
Your users simply open a file—Doconut handles the rest.
Full-stack conversion engine: server-side document processing at scale
Doconut’s conversion engine gives you reliable, consistent output while preserving formatting, fonts, colors, metadata and attachments where applicable.
| Source → Target | Key Features |
|---|---|
| PDF ↔ DOCX | Maintains layout, fonts, tables, vectors |
| Excel ↔ PDF | Optimized for speed in the 25.10.0 release |
| PowerPoint → JPG/WEBP | Ideal for slides, previews, learning apps |
| CAD (DWG) → PDF/PNG | Accurate vector-to-raster conversion |
| Email (EML/MSG) → PDF/HTML | Preserves structure and attachments |
All conversions are stream-based, keeping memory usage low and suitable for high-traffic portals, CRMs, dashboards, and document workflows.
Advanced interaction layer for document management
Doconut doesn’t just display files — it makes them actionable.
- Intelligent search & OCR
Users can search text instantly, including in scanned PDFs thanks to integrated OCR. - Annotations
Highlighting, drawing, shapes, notes, callouts — all part of the built-in annotation tools. - Controlled printing & export
Printing and exporting can be managed server-side for extra control in enterprise systems.
These features turn Doconut from a simple viewer into a complete document interaction platform.
