What is an HWP file?
The HWP format is a proprietary document file generated by Hancom Office Hangul, the dominant word processing software in South Korea, widely used by government and public institutions. Older versions rely on a compound binary file structure (OLE2) similar to early Microsoft Word DOC files, while distinct encoding mechanisms are used to support the Korean alphabet (Hangul). The format is distinct from the newer XML-based HWPX and often requires specific conversion libraries for interoperability outside the Hancom ecosystem.
How to open an HWP file
Native support is restricted to Hancom Office (Windows/macOS/Linux) and the free Hancom Office Viewer. For users without this software, Hancom provides a cloud-based web viewer called Hancom Docs. Third-party support is limited; however, LibreOffice (via libhwp) offers partial rendering capabilities, and the Naver Whale browser includes a built-in extension for viewing HWP files directly.

What is an EPUB file?
EPUB (Electronic Publication) is an open e-book standard maintained by the World Wide Web Consortium (W3C), originally developed by the International Digital Publishing Forum (IDPF). It utilizes the Open Container Format (OCF) based on ZIP compression to package XHTML content, CSS styling, and XML metadata. EPUB supports reflowable content, allowing text to adapt to various screen sizes, and fixed-layout rendering for graphic-heavy publications. The current version, EPUB 3.2, supports HTML5, SVG, and JavaScript interactivity.
How to open an EPUB file
EPUB files require dedicated e-reader software as most operating systems do not natively render them. On desktop environments (Windows/macOS/Linux), Calibre is the industry-standard management tool, while Adobe Digital Editions handles DRM-protected files. For mobile devices, Apple Books (iOS) and Google Play Books (Android) provide native rendering. Browser-based extensions like EPUBReader for Chrome allow viewing without standalone software.
