A licensed C#/.NET library that converts DOCX (and legacy DOC) documents straight to PDF from your own process - no Microsoft Word or Office installation, no COM interop.
dotnet add package Hytone-PDF
using Hytone.Pdf; HytonePdf.SetLicense("HYT1...."); var doc = HytonePdf.LoadDocument("report.docx"); doc.Save("report.pdf"); // that's it - no Word, no server, no COM
Three steps, all inside your own process.
Add Hytone-PDF from NuGet - no separate runtime, no external service to stand up.
Call SetLicense once at startup. No key at all runs a free evaluation mode.
Load a DOCX or DOC file and get back a PDF - a single method call, synchronous, done.
A focused conversion library, not a document editor.
Runs entirely in your own process - no Word installation, no COM interop, no server-side Office licensing headaches.
Converts modern DOCX documents directly, and legacy Word 97-2003 DOC files via built-in DOC-to-DOCX conversion first.
Combine multiple PDFs into one, or append a freshly-converted document straight onto an existing PDF, in a single call.
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 hosted endpoint 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.
Common questions from developers evaluating Hytone-PDF.
No. Hytone-PDF converts DOCX and legacy DOC files to PDF entirely within your own .NET process - it never launches or depends on Microsoft Word or Office.
Hytone-PDF currently targets .NET 8.0. It's a plain class library, so it works from any .NET language including C#, F#, and VB.NET.
Yes. Legacy Word 97-2003 .doc files are converted to .docx first, then straight to PDF, using the same conversion pipeline.
Yes. Installing Hytone-PDF without a license key runs it in evaluation mode: output is capped at 1 page and watermarked, with no license key required.
Yes, with an Enterprise license - it permits using a single key across multiple downstream clients, intended for products or services built on top of Hytone-PDF. See Purchase License for details.
