How to Feed HWP Files to ChatGPT & Claude
Turn Korean documents (HWP/HWPX) into the Markdown that AIs read best. No installation, no sign-up required.
When you drop a Korean .hwp file straight into AIs like ChatGPT, Claude, or Gemini, they often fail to read it correctly or mangle tables and formatting — because HWP is a closed format used only in Korea. Convert it to Markdown (.md) with the tool above and the AI understands the document structure precisely, dramatically improving summarization, translation, and analysis quality.
Done in 3 steps
- Drop your HWP/HWPX file into the converter above. Drag and drop or click to choose — conversion starts automatically.
- Copy the converted Markdown or download it as a
.mdfile. If the document has images, you can grab them together in a zip. - Paste it into your AI chat or upload the
.mdfile. The AI now reads your document accurately.
Why convert to Markdown?
- The format AIs read best — large language models are trained on Markdown and parse headings, lists, and table structures precisely.
- Less broken formatting — tables and paragraph structure come through far more reliably than feeding the raw HWP.
- Token efficiency — clean, lean text conveys the same content in fewer tokens, ideal for long documents.
- Images extracted too — images inside the document are pulled out and downloadable as a zip.
Frequently asked questions
Can't I just upload the HWP file to ChatGPT directly?
HWP is a Korea-specific closed format, so AIs often fail to read its contents or break tables and formatting. Converting to Markdown (.md) lets the AI understand it most accurately.
Are my files sent to an external server?
No. Conversion happens 100% inside your browser (WebAssembly). Documents are never uploaded, so even sensitive files like official documents or contracts stay safe.
Are HWPX files supported too?
Yes. Both .hwp and .hwpx are supported.
Does it handle documents with lots of tables?
You can pick a table conversion mode — Auto (merged cells as HTML), Markdown-only tables, or HTML-only tables — so tables come out clean for your document.
Is there a cost?
It is free. Use it right away with no installation or sign-up.
