Read the full description
Openhwp andhwpx files (the Korean word processor format) in your browser, with nothing to install and no account. Unlike converter sites that upload your document to a server, the parsing runs on your device with WebAssembly, so the file never leaves it. Read the pages, copy text, print, or save the document as a PDF. Free. Fonts and line breaks may differ a little from the original, and some documents may not open.

Partial The viewer and PDF export UI are straightforward in the browser, but HWP is a complex binary/compressed format, and faithful layout rendering is the hard part.
What it would actually take: Use WebAssembly with an existing open-source HWP/HWPX parser (or port one) and the publicly documented format specs, then build a browser UI on top. The difficult part is rendering pages with accurate fonts, tables, and layout, which requires format and typography expertise and extensive testing against real documents.
