Document Viewer and Converter for ASP.NET Core, MVC and WebForms

Universal web document viewer which works on both desktop and mobile browsers.

Crystal-clear zooming. High resolution rendering, preserving text and graphics (no rasterization) exactly as they are in the original.

Fast document loading, the whole document is not loaded at once, document pages are loaded as you are about to view them.

Search text within document. Navigate with bookmarks/outlines.

Change page layout modes (e.g. single page or facing pages), rotate pages and view on full screen.

Print, download original or download as PDF inside the viewer.

Secure document viewing, copy protection (DRM). Viewed documents are encrypted so they are copy-protected out of the box. Ability to disable downloading the original document or replicating it via printing or selecting and copying text.

Watermark document pages with text or image. Customize the watermarks with wide range of options e.g. position, size, rotation, opacity, color.

Pre-higlight keywords in the document, e.g. if you launch the document viewer from a search results page, you can higlight the searched keywords.

Self-contained conversion engine, no external dependencies, e.g. you don't need to install Microsoft Office on your server.

Single managed DLL which works both on 32-bit and 64-bit for hassle-free development and deployment.

Supports being used in desktop or console applications for converting between document formats. Only the document viewer is dependant on web applications.
