Hanjjok: PDF & HWP Viewer

Open the HWP and HWPX files you were sent, then turn them into a PDF or print them — from your phone.

Hanjjok is a light viewer for HWP and HWPX, the document format used by Korean government offices, public institutions and schools. It is built around a single situation: a file has arrived, you need to read it and do something with it, and there is no PC in front of you.

What it does

- Opens HWP and HWPX quickly. Pick Hanjjok from the share sheet in KakaoTalk, Mail or Files and the document opens.
- Reads PDF as well, so an attachment of either kind lands in the same place.
- Prints over AirPrint to any printer your iPhone or iPad can reach.
- Converts to PDF in one tap, then passes it on to mail, a messenger or a cloud drive.
- Exports only the pages you choose, as a PDF or as images, to share or to print.
- Extracts the text of a document so you can copy or share the wording itself.
- Detects landscape pages and prints them in landscape without being asked.
- Shows a first-page thumbnail, so you can tell which document is which.
- Keeps what you opened in one list, and clears out the ones you no longer need.
- Handles your documents offline. No account, no sign-up, no cloud sync — every document you open is processed on the device and is not transmitted anywhere.

Korean documents on an English device

The app follows your device language, so Hanjjok itself reads in English. A Korean font ships inside the app and draws the text in your documents, so Korean should appear as letters rather than empty boxes even on a device with no Korean font installed. Document content is never rewritten or translated — you see the file as it was written.

Advertising

While a document is open and you are reading it, Hanjjok shows no advertising. An ad appears only at a result action — converting to PDF, printing — and only briefly, and the result follows immediately after. If you would rather not see advertising at all, Remove Ads is a one-time purchase that lasts for the lifetime of the app. You can also watch a single ad to switch advertising off for 24 hours.
