Hangul has been the leading word processor in South Korea since the early 1990s, and the public sector adopted it as its default, so official forms, school assignments, job applications and court documents circulate as .hwp files. Hancom publishes the format specification, and several versions exist.<\/p>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th>Property<\/th>\n<th>HWP file<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Extension<\/td>\n<td>.hwp (also .hwpx, .hwt for templates)<\/td>\n<\/tr>\n<tr>\n<td>Developer<\/td>\n<td>Hancom Inc.

Hangul 2002 introduced HWP 5.0, a compound binary file (the same container type as old Word .doc files) in which the document text, styles and images sit in separate compressed streams. Most .hwp files in circulation today are HWP 5. HWPX is the newer open format: a ZIP archive with XML parts, published as the Korean national standard KS X 6101 (OWPML) and used by recent Hancom Office versions and by government systems that require open formats. A program that reads HWP 5 does not automatically read HWPX, and vice versa.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_do_I_open_an_HWP_file\"><\/span>How do I open an HWP file?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol>\n<li><strong>Hancom Office Hanword.<\/strong> The native application, sold by Hancom, with a free trial.

Layout of complex documents may shift.<\/li>\n<li><strong>Convert to PDF or DOCX.<\/strong> If you only need to read or forward the document, convert it. The <a href=\"https:\/\/www.coolutils.com\/online\/HWP-to-PDF\">HWP to PDF online converter<\/a> renders the file as a PDF that opens anywhere, and <a href=\"https:\/\/www.coolutils.com\/online\/HWP-to-DOCX\">HWP to DOCX<\/a> produces a Word document. Both run in the browser and need no Korean software.<\/li>\n<\/ol>\n<p>LibreOffice has an import filter for the legacy HWP 3.x format only, so it fails on modern HWP 5 files. Google Docs does not open HWP either.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_do_I_convert_HWP_to_PDF_or_Word_in_batch\"><\/span>How do I convert HWP to PDF or Word in batch?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Translators, law firms and universities that receive HWP files regularly need more than a one-off converter. <a href=\"https:\/\/www.coolutils.com\/TotalDocConverter\">Total Doc Converter<\/a> converts folders of HWP files to PDF, DOCX, DOC, RTF, TXT, HTML or JPEG on Windows without Hangul installed. According to the product page it covers the whole family: binary HWP 5, older HWP 3, XML-based HWPML and zipped HWPX. It keeps the folder structure, can combine several documents into one PDF, and runs from the command line for scheduled jobs. The 30-day trial is free and asks for no card or email; a Personal license starts at $49.90.<\/p>\n<p>For single files, the online pairs are enough: <a href=\"https:\/\/www.coolutils.com\/online\/HWP-to-JPG\">HWP to JPG<\/a> for a page image and <a href=\"https:\/\/www.coolutils.com\/online\/HWP-to-TXT\">HWP to TXT<\/a> to pull out the plain text for translation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_asked_questions\"><\/span>Frequently asked questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"What_program_opens_HWP_files\"><\/span>What program opens HWP files?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Hancom Office Hanword opens and edits HWP files natively.
