What it does

A focused conversion library, not a document editor.

No Office dependency

Runs entirely in your own process — no Word installation, no COM interop, no server-side Office licensing headaches.

DOCX and legacy DOC

Converts modern DOCX documents directly, and legacy Word 97-2003 DOC files via built-in DOC-to-DOCX conversion first.

PDF merging

Combine multiple PDFs into one, or append a freshly-converted document straight onto an existing PDF, in a single call.

Thread-safe stream API

A stateless, concurrent-safe conversion overload for servers and any multi-threaded caller.

About Hytone-PDF

Part of the Hytone-Tools family of developer libraries.

Hytone-PDF is a commercial .NET library, distributed as a standard NuGet package — you install it and call C# methods directly in your own process, the same way you'd use any other library (there's no separate service to run or API to call over the network).

It's built for one job: getting a faithful PDF out of a DOCX or legacy DOC file without needing Microsoft Word or Office installed anywhere in the pipeline. See the Install page for exact usage, supported .NET versions, and code examples, or Purchase License for pricing.
