All HWP parsing and PDF generation runs entirely in your browser. Your document is never uploaded to a server.
This free HWP to PDF converter is a browser-based tool that transforms Hangul Word Processor documents (.hwp) into readable PDF files. It parses the OLE Compound File Binary structure, decompresses the BodyText streams, and extracts Korean and multilingual paragraph text. No Hancom Office installation, no server upload, no cost.
HWP to PDF Conversion Features
A complete Hangul Word Processor document to PDF converter built on OLE binary parsing and browser-native decompression.
Korean Hangul Text Support
HWP documents store text as UTF-16 LE encoded Unicode. The converter reads Korean Hangul syllable blocks (U+AC00 to U+D7A3) and all other Unicode characters directly from the binary stream.
Paragraph Structure Preserved
HWPTAG_PARA_TEXT records are extracted in reading order from each BodyText section, preserving the original paragraph breaks and document flow from the HWP source file.
Files Stay on Your Device
Unlike cloud-based HWP converters that transmit your document to a remote server, this parser runs entirely in the browser. No account, no data storage, no privacy risk for sensitive government or official documents.
Live Preview
After uploading an HWP file, the converter immediately renders a formatted preview of the extracted text so you can review the content and paragraph layout before downloading the PDF.
OLE CFB and Zlib Parsing
The converter parses the OLE Compound File Binary container, navigates the directory tree to locate BodyText streams, and decompresses them using the browser's native DecompressionStream API.
Browser-Based on Any Device
Works on Windows, macOS, Linux, iOS, and Android in any modern browser that supports the DecompressionStream API. No Hancom Office, no LibreOffice, no desktop software of any kind required.

Frequently Asked Questions
How do I convert an HWP file to PDF online for free?
Upload your .hwp file to this converter, choose a page size and orientation, then click Download PDF. The browser parses the HWP binary format, decompresses the BodyText, and generates a formatted PDF. No Hancom Office or desktop software required.
What is an HWP file?
HWP is the native document format of Hangul Word Processor by Hancom Inc., widely used in South Korea for government forms, official documents, and academic submissions. HWP 5.0 uses an OLE Compound File Binary container with zlib-compressed BodyText streams storing text in UTF-16 LE encoding.
Can I open HWP files without installing Hancom Office?
Yes. This browser-based HWP to PDF converter opens .hwp files without Hancom Office, Microsoft Word, or any desktop application. Upload the file in your browser and download the document content as a universally readable PDF file instantly.
Does converting HWP to PDF preserve Korean text and paragraph structure?
Yes. The converter extracts UTF-16 LE encoded Korean Hangul characters directly from the HWP binary stream and preserves paragraph breaks from the HWPTAG_PARA_TEXT records. All Unicode characters including Hangul syllable blocks are rendered correctly in the PDF output.
What is the difference between HWP and HWPX?
HWP 5.0 is a proprietary binary format using OLE Compound File Binary with zlib-compressed streams. HWPX is a newer open XML-based format introduced in Hancom Office 2014 that packages content in a ZIP archive similar to DOCX. This converter supports HWP 5.0 binary files only.
Can I convert a password-protected or encrypted HWP file?
No. Password-protected or encrypted HWP files cannot be parsed by any browser-based tool because the encryption prevents access to the BodyText streams. Only unprotected HWP 5.0 documents can be converted using this tool.
