How to Open Hancom Hangul (HWP / HWPX) Files Online — No Software Required, Works on iPhone
Jun 21, 2026
Have you ever received a Hangul file (.hwp or .hwpx) from a government office or business contact, only to find you can't open it because you don't have Hancom Office installed? HWP is the proprietary file format of Hancom's Hangul word processor, which is dominant in Korean offices and government agencies. Because it's a specialized format, standard apps like Microsoft Word or macOS Preview can't reliably open it. On iPhone and Android in particular, there's no built-in HWP viewer, so tapping a mail attachment often results in an "unsupported format" error. This guide covers how to open Hangul files for free, without installing any software, across different situations.
View HWP and HWPX files directly in your browser — no installation or sign-up. Upload the file and it converts automatically so you can scroll through the content (works on mobile too).
Open Document Viewer →Method 1. View Instantly with an Online Web Viewer (No Installation — Recommended)
Upload your file to the FreeSign Document Web Viewer and view it in your browser without Hancom Office. No account required.
- Upload the file — Select or drag and drop an HWP or HWPX file.
- Automatic conversion and display — The file converts in moments and you can scroll through the content in your browser.
- Save (optional) — Download as a PDF if you want to keep or share it.
Method 2. Opening on iPhone or Android
Mobile devices typically have no HWP viewer built in — but the web viewer solves this without installing any app.
- Long-press the Hangul file received via email or a messaging app and choose "Share → Open in Browser" or "Save to Files."
- Open the web viewer in your mobile browser and upload the saved file.
- Scroll through the content and save as PDF if needed.
Method 3. Using the Hancom Viewer on a Windows PC
On a Windows PC, you can also install Hancom Office or the free "Hancom Office Viewer" to open HWP files. However, installation is cumbersome and it doesn't work on mobile — so for a document you only need to read once, the web viewer is far quicker.
Saving as PDF for Long-Term Storage
Converting a received Hangul file to PDF means it will open on any device and is easy to share. Use the Hangul → PDF converter to turn HWP or HWPX files into PDF. If you're curious about exactly what HWPX is, see the article What is an HWPX file? — HWPX is the XML-based successor format introduced by Hancom.
No installation or sign-up. Works on mobile too. Save as PDF when you're done.
Open Document Viewer →Frequently Asked Questions
Q. Does it really work without Hancom Office installed?
Yes. The web viewer converts the file on the server side and displays it in your browser, so no local installation of Hancom Office is needed.
Q. Does it work on iPhone?
Yes. The viewer runs entirely in a mobile browser, so it works on iPhone, iPad, and Android — no app installation required.
Q. Is my uploaded file saved anywhere?
The file is used only temporarily for conversion and is not retained on the server afterward.
Q. Can I edit the document after opening it?
The web viewer is for viewing and saving as PDF only. If you need to edit the content, use the Hangul → Word (DOCX) converter to get an editable file, then edit it in Microsoft Word.
