How to Feed HWP Files to ChatGPT & Claude
Convert Korean documents (HWP/HWPX) to Markdown that AI reads easily. No installation or sign-up.
When you drop a Korean .hwp file straight into AIs like ChatGPT, Claude, or Gemini, they often fail to read it or break the tables and formatting. HWP is used almost only in Korea, so AI support for it is weak. Convert it to Markdown (.md) with the tool above, and the headings and tables reach the AI as plain text.
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?
- Structure stays as text — headings are written with
#, lists with-, and tables with|, so the AI does not have to guess the layout. - Less broken formatting — tables and paragraphs come through more reliably than with the raw HWP.
- Fewer tokens — without layout data, the same content takes fewer tokens. The longer the document, the bigger the difference.
- Images come out too — images inside the document are extracted and can be downloaded as a zip.
Frequently asked questions
Can't I just upload the HWP file to ChatGPT directly?
AI tools support HWP poorly, so they often fail to read the contents or break tables and formatting. Converting to Markdown (.md) first avoids most of that.
Are my files sent to an external server?
No. Conversion runs inside your browser (WebAssembly). Nothing is uploaded, so official documents and contracts never leave your device.
Are HWPX files supported too?
Yes. Both .hwp and .hwpx are supported.
Does it handle documents with lots of tables?
You can choose how tables are converted: Auto (HTML only for tables with merged cells), Markdown tables only, or HTML tables only. Pick whichever suits the document.
Is there a cost?
It is free. You can use it right away without installing anything or signing up.
