HWP 무료 오픈앱

This is a lightweight viewer that allows you to open Hancom Hangul documents (.hwp) and Hangul standard documents (.hwpx) directly on your mobile device. It is completely ad-free, requires no payment, does not collect any user information, and is not transmitted to external servers.

I created this ad-free version because there were way too many ads when trying to view public documents.

[Key Features]

• Supports both HWP 5.0 and HWPX — Uses an open-source engine (rhwp) based on the government KS X-616 standard

• Instant Open — Double-tap an hwp file in a file manager, KakaoTalk, Mail, etc. to open it immediately

• No Ads · No Payments — Free for life

• Fast Page Navigation — Drag the slider on the right edge or tap the page number at the bottom to jump directly to the desired page

• Pinch Zoom · Double-tap Reset — Freely zoom in/out of pages

• Left/Right Swipe — Turn pages with a single finger

• Offline Operation — Can be used without an internet connection

[Secure Processing]

• 100% In-Device Processing — Files open only within the user's phone and are not transmitted to any server

• Zero Personal Information Collection — No account registration, no usage history tracking

• Minimal Permissions — Uses no permissions other than reading hwp files
