Why convert HWP to HTML
Converting from HWP to HTML eliminates software compatibility bottlenecks. While Hangul Word Processor Document (.hwp) is specialized for its native workflow, HTML Document (.html) ensures effortless viewing, editing, and integration across standard desktop and mobile tools.

HWP vs HTML — Strengths and limitations
What each format does best, and where it falls short.
HWP Strengths
- Precision Korean Hangul/Hanja typography, vertical writing modes, and complex administrative grid tables.
Limitations
- Proprietary OLE2 binary structure is incompatible with standard office suites outside South Korea.
HTML Strengths
- Universal — every browser, OS, email client, and document reader displays HTML.
- Plain text, human-readable, grep-able, and diffable in git.
- Flexible — pages render even with broken or partial markup (error-tolerant parser).
- Carries structure, styling (CSS), and behavior (JavaScript) in one file.
- Accessibility-friendly when written with semantic tags and ARIA attributes.
Limitations
- Error tolerance allows sloppy markup to hide real bugs.
- Rendering depends on browser engine — pixel-perfect cross-browser output is an art form.
- Security-sensitive — unsafe HTML can execute scripts or leak data (XSS vulnerabilities).
Quality & Compatibility
Our pandoc conversion pipeline preserves document hierarchy, character encoding (UTF-8), vector/pixel fidelity, and structural metadata when transforming HWP into HTML.
Tips for Best Results
- Be aware that HWP proprietary OLE2 binary structure is incompatible with standard office suites outside South Korea — keep that in mind when reviewing the converted file.
- Take advantage of HTML's strength: universal — every browser, OS, email client, and document reader displays HTML.
- Use the highest-quality HWP source you have — conversion can't recover detail that was already lost.
- For bulk jobs, convert one file first to verify settings, then upload the rest.
Limitations
Password-protected or corrupted .hwp files must be unlocked before conversion. Free tier supports up to 25 MB per file (up to 2 GB with Kaiju Cloud).
