How HWP to Markdown works

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

Built for JavaScript runtimes

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 HWP 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

HWP files can stay inside your application or browser.

Content detection

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

Deterministic parsing

The same HWP file produces repeatable Markdown without model inference.

Small runtime surface

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

HWP for AI agents

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

GitHub-Flavored Markdown.

Can I install only the HWP converter?
