HWP Viewer

The HWP Viewer is a browser-based tool that enables immediate access to Hangul Word Processor files without installing native software. It is suitable for individuals who receive .hwp documents, distributed teams needing rapid document review, and educators sharing course materials. Conceptually, the tool loads a binary HWP file, parses its structure, and renders a faithful view in the browser, preserving core layout, text, and embedded content. Core features include a client-side parsing engine, a renderable document model, and safe export options to HTML or PDF for downstream workflows. The tool emphasizes reliability and privacy: parsing happens entirely in the user's browser, and exported outputs reflect the original content with practical font fallbacks when needed. Use cases include quick content verification, side-by-side comparison with other formats, and lightweight sharing for teams lacking HWP software. Unique value derives from in-browser rendering without server processing, immediate accessibility, and export capabilities that integrate with typical document workflows. Advanced capabilities may include multi-document previews, offline rendering via WebAssembly, and programmatic access through a simple API. Error handling covers unsupported formats, corrupted files, and oversized documents with clear diagnostics and partial renders when feasible. The tool supports Unicode and Korean text, with locale defaults to en-US and no server-side data handling, aligning with general privacy expectations. Assumptions include browser-based operation with WebAssembly availability as an optional enhancement; exclusions cover editing, server rendering, non-HWP formats, watermarking, and long-term storage of documents.
