How HWT to Markdown works

  1. HWT
  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 HWT 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

HWT files can stay inside your application or browser.

Content detection

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

Deterministic parsing

The same HWT file produces repeatable Markdown without model inference.

Small runtime surface

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

HWT for AI agents

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

FAQ

No.

Does it require native addons or WASM?

No.

What does it output?

GitHub-Flavored Markdown.

Can I install only the HWT 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.
