DocToolkit

HTML in. Word and PDF out. Nothing else installed.

NuGet Downloads Runs on Linux, arm64, Windows and macOS MIT

You have a Linux container, a Word template and a PDF due on Friday. The usual answers are a headless Chrome, LibreOffice, or a licence with a revenue threshold.

DocToolkit is one NuGet package instead. It is pure managed code. It restores, builds and runs the same on your laptop and in the container.

Install

dotnet add package Ank.DocToolkit

// HTML in, a Word document and a PDF out. No browser, no LibreOffice, nothing to install.
byte[] docx = await HtmlToDocxConverter.ConvertAsync("<h1>Invoice 2026-114</h1>");
byte[] pdf = await HtmlToPdfConverter.ConvertAsync("<h1>Invoice 2026-114</h1>");

// Read a document back, edit one you were given, and lock it when you are done.
string text = DocxEditor.ExtractText(docx);
byte[] locked = PdfEditor.Protect(pdf, new PdfProtection { UserPassword = "s3cret" });

That is the whole setup: no browser download, no apt-get, no config file. It targets net8.0 and net10.0.

FAQ

Does it need Chrome or LibreOffice? No. Every PDF is rendered from a real Word document, in managed code.

Can I use it at work? Yes. It is MIT licensed, and every dependency is MIT, Apache-2.0 or BSD.

Does it reach the network? Not by default. Remote images are the one opt-in, and that stays bounded.

Is it trim-safe and ready for native AOT? Yes. CI publishes a trimmed and a native-AOT app and runs both. ClosedXML still emits warning IL2090.

What will it not do? CSS layout, mixed page setups and multi-line headers, among a few others. The list is in Known limitations.

## [0.61.0](https://github.com/Ank-KhoaHo/DocToolkit/compare/v0.60.1...v0.61.0) (2026-11-13)


A Word form can now say which of its fields are locked before you fill it. The package page on
nuget.org also gets a short front page; the full reference moved, unchanged, to the
[Reference](https://ank-khoaho.github.io/DocToolkit/guides/reference.html) page of the docs site.

### Added

* **Core:** `DocxFormField.IsLocked` is true when a content control's content is locked (`w:lock` set to `contentLocked` or `sdtContentLocked`), which is exactly when `DocxForm.Fill` refuses to write it. A form UI can grey the field out instead of finding out from an exception. ([#551](https://github.com/Ank-KhoaHo/DocToolkit/issues/551)) ([1a6e405](https://github.com/Ank-KhoaHo/DocToolkit/commit/1a6e4052cb5c45d00fb94911a66b3789bd3ddea1))
* **Core:** `DocxFormIssueKind.LockedControl` (value 10). ([#551](https://github.com/Ank-KhoaHo/DocToolkit/issues/551)) ([1a6e405](https://github.com/Ank-KhoaHo/DocToolkit/commit/1a6e4052cb5c45d00fb94911a66b3789bd3ddea1))

### Changed

* **Core:** `DocxForm.Fill` now writes a control locked only against deletion (`sdtLocked`), as Word does, and keeps the lock. Since 0.54.0 it refused all three lock kinds alike. ([#551](https://github.com/Ank-KhoaHo/DocToolkit/issues/551)) ([1a6e405](https://github.com/Ank-KhoaHo/DocToolkit/commit/1a6e4052cb5c45d00fb94911a66b3789bd3ddea1))
* **Core:** `DocxForm.Validate` reports a value aimed at a content-locked control as `DocxFormIssueKind.LockedControl`; it reported `Other` before. A consumer that switched on `Other` for locks needs the new case. ([#551](https://github.com/Ank-KhoaHo/DocToolkit/issues/551)) ([1a6e405](https://github.com/Ank-KhoaHo/DocToolkit/commit/1a6e4052cb5c45d00fb94911a66b3789bd3ddea1))
