HWP and HWPX to PDF
Convert Korean Hangul documents (.hwp and .hwpx) to PDF or plain text in your browser. Text, tables and pictures are kept, and the file is never uploaded.
How it works
- HWPX is a ZIP of XML (OWPML). Older .hwp files are a binary format that Hancom has published; Nibbo reads both with its own parser.
- Paragraphs, bold and italic, font sizes, tables with merged cells, and embedded pictures are laid out on pages of the original size.
- Korean text, including Hanja, uses Noto Sans KR and Latin text uses Noto Sans (both SIL Open Font License). Only the characters your document uses are embedded, so the PDF stays small.
- The whole conversion runs in a background thread on your device. The fonts are part of this site and are cached after the first use.
Questions
Will the PDF look exactly like in Hangul?
Close, not identical. Headers, footers, footnotes, text boxes, shapes, equations and multi-column layouts are not carried over, and the original fonts are replaced. Nibbo lists anything it skipped. For a pixel-exact copy, print to PDF from Hancom Office or the free Hangul Viewer.
My .hwp file gives an error. Why?
Password-protected and “distribution” (read-only) documents are encrypted, and very old HWP 3 files use a different format. Open the file in Hangul and save it as .hwpx, then convert that.
Can I get just the text?
Yes. After converting, download the plain text or copy it, for example to translate it.
Is my document uploaded?
No. It is read and converted inside this browser tab, and nothing is sent to a server.
Why is the first conversion slower?
The Korean font is about 6 MB per weight and is downloaded from this site the first time, then cached for offline use.
