How HWTX to Markdown works

  1. HWTX
  2. HWP / HWPX parsing
  3. paragraphs · headings · tables
  4. GitHub-Flavored Markdown

Built for JavaScript runtimes

Node.js

Read local files, uploads, S3/R2 objects, and other byte sources.

Cloudflare Workers

Parse Hangul files directly inside Workers without Hangul Word Processor or a native binary.

Browser

Convert HWTX locally without uploading it to a server.

Edge

Run the same TypeScript converter in compatible Edge runtimes.

What @mdgate/hwp extracts

  • HWPX / HWTX paragraphs and line breaks
  • Heading styles when present
  • Tables in HWPX
  • HWP 5 PARA_TEXT records when the layout is recognizable
  • Readable UTF-16 strings and PrvText preview as a fallback
  • Encrypted and distribution-locked document detection

Why @mdgate/hwp

Runs where your JavaScript runs

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

HWTX files can stay inside your application or browser.

Content detection

Recognizes HWTX files from their contents, not only the filename.

Deterministic parsing

The same HWTX file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.

HWTX for AI agents

Turn HWTX files into content your agent can actually work with.

FAQ

Can I convert HWTX to Markdown without uploading it?

Yes. HWTX files can be converted locally in the browser.

Yes. @mdgate/hwp runs directly in Cloudflare Workers.

No.

Does it require native addons or WASM?

No.

What does it output?

GitHub-Flavored Markdown.

Can I install only the HWTX converter?

No. The converter prefers structured text when it can find it, and falls back to extracted strings rather than pretending it has a full HWP renderer.
