Convert HWP to DOCX Online for Free

HWP and DOCX are editable documents with different internal rules

HWP is Hancom Hwp’s native word-processing format. DOCX is Microsoft Word’s Office Open XML document format, a ZIP-based package that separates document content, styles, numbering, headers, footers, media, properties, and relationships into parts. Both formats can hold text, tables, pictures, drawings, and page layouts, but they do not express all those features in the same way. HWP-to-DOCX is an interoperability conversion that maps one editor’s document model into another; it is not a guaranteed byte-for-byte or object-for-object preservation operation.

Hancom states this directly in its compatibility documentation: saving an Hwp document as a Word 2007 DOCX or opening a DOCX in Hwp can produce compatibility issues because the two applications use different data-processing and format-designation methods. Its documented HWP-to-DOCX problem areas include equations, proofing symbols, form controls, table size, font shadow continuity, missing underline, partial strikethrough, partial outline, partial border or background, paragraph spread, partial line spacing, and partial paragraph border or background. These are specific review targets, not vague warnings to “check formatting.”

Keep the original HWP and create a separate DOCX working copy. The HWP remains the source for any feature that did not map faithfully; the DOCX becomes the version to edit in Word after it passes a comparison review. Do not allow both documents to receive untracked changes indefinitely, because differences in font, table, object, and page behavior make later reconciliation much harder than correcting the initial conversion carefully.

The conversion maps Hancom objects into WordprocessingML parts

A DOCX is not one XML file with a new extension. It is an Office Open XML package where the main Word content is commonly word/document.xml, supported by related parts for styles, lists, notes, images, headers, footers, comments, and settings. HWP content must be interpreted by a conversion engine and represented through these Word structures. Plain paragraphs may map well, while objects that depend on Hancom-specific layout or drawing rules may need approximation, be flattened to images, or display with changed settings in Word.

Hancom’s documentation describes concrete examples when content moves in the other direction too. When copying Hwp objects into Word, tables can have partial border or diagonal-line differences; pictures can gain white space or partial-line differences; lines and drawing objects can change end style, position, white space, or shadow; and equations, charts, and sound objects can be affected. These examples explain why a DOCX can open and still need page-by-page comparison. Successful file opening establishes package validity, not that every table border, equation, and drawing has the same meaning or location.

The source retains matters that the DOCX cannot infer later. Hwp has HWP-specific compression choices, preview images, backup behavior, and password settings. Hancom says HWP compression does not apply when saving as DOCX and does not create an HWP backup for DOCX saves. Make a deliberate named copy before conversion, then treat the DOCX as a new branch. If a later Word edit introduces a problem, the original HWP and first verified DOCX provide the evidence needed to identify whether the difference came from conversion or subsequent editing.

What an editable Word copy improves and what it can change

• Word users can edit the result in a familiar document type: DOCX is the standard modern Word package rather than a Hancom-native file.
• Text often transfers more easily than visual objects: equations, proofing symbols, controls, drawings, charts, and special borders are documented compatibility risks.
• Table geometry needs a direct check: Hancom lists table size when saving HWP as DOCX and table border or diagonal-line differences in Hwp-to-Word object exchange.
• Typography can change in subtle ways: Hancom specifically lists missing underline and partial shadow, strikethrough, outline, border, and background behavior.
• HWP compression and backup rules do not follow the DOCX: Hancom says Compress and Save does not apply to DOCX and a DOCX save does not create the HWP backup file.
• Security must be reconsidered: HWP/HWT password-save options do not establish an equivalent DOCX protection result, so set needed Word protection separately.

DOCX is the useful destination when a recipient must revise prose, comments, tables, and conventional Word content. It is not a guarantee that a complex HWP design will remain an identical editable drawing. For documents with heavy layout, equations, or specialized objects, pair the editable DOCX with a checked PDF reference and retain HWP as the authoritative original.

Hancom documents the exact compatibility checks worth making

Start the review with Hancom’s HWP-to-DOCX list rather than a random scroll. Check every equation and proofing symbol; each form control; table width, height, and line behavior; underlines, strikethroughs, outlines, shading, and borders; and paragraphs that use spread, unusual line spacing, or partial borders. These are the items Hancom explicitly names as potentially different when an Hwp document is saved as a Word 2007 DOCX. Compare them in the source and then in Word’s Print Layout, not only in a quick browser preview.

Then inspect the items Hancom lists for DOCX opened in Hwp, because they reveal the broader boundary between the applications: merged tables, fonts, spacing, chart legend size, drawing line style and location information, arrow style, line weight, drawing objects, WordArt, organization charts, SmartArt, and OLE objects including video, sound, bitmap images, and WordPad documents. A source with analogous rich objects needs a careful Word-side review even if its first body-text pages look perfect.

Hancom provides Save As and Save a Copy options for files intended for other programs, and its current Korean Hanword help lists DOCX as a selectable Word document format. Save a new named copy rather than overwriting the original HWP. If recipients will revise the DOCX, establish one chosen working file after the comparison, enable the appropriate review process in Word, and avoid sending changes back and forth between independently edited HWP and DOCX versions.

When Word output differs, repair the mapped feature rather than the filename

A table border, diagonal line, or size changes. This is a documented cross-format issue. Compare the table’s structure and dimensions in Hwp and Word, then rebuild or simplify the affected Word table with native Word controls if DOCX is now the working format. Do not judge the table only by the first row: review merged cells, repeated headers, empty cells, border styles, and the final row near a page break.

An equation, chart, drawing, or form control is missing or uneditable. Identify the original object type before trying a generic re-save. Hancom explicitly calls out equations, charts, drawing objects, form controls, WordArt, SmartArt, and OLE-related content as compatibility boundaries. Replace an affected item with a Word-native equivalent where future editing matters, or use a verified image/PDF reference where exact appearance matters more than editability.

Text looks similar but line spacing, underline, shadow, or background is wrong. Check the exact paragraph and font settings named by Hancom’s compatibility table. A font substitution can also alter line width, so confirm availability of the required font in Word before changing margins or manually inserting breaks. Fix the DOCX styles if it is the selected working copy, then recheck page flow; do not attempt to solve a font-metric issue by editing individual lines in an exported PDF.

The source was password-protected and the DOCX opens without the expected restriction. Treat this as a new delivery format with its own security configuration. Hancom’s Save As documentation restricts document-password setting to HWP and HWT. Configure needed Word document protection separately and verify it in the intended Word environment; conversion alone does not prove an equivalent security policy was created.

HWP-to-DOCX review points with a real consequence

Questions before treating a converted HWP file as the Word master

Why did the DOCX open successfully but still look different?
HWP and Word use different processing and format rules. Hancom specifically documents possible differences in objects, fonts, paragraphs, form controls, equations, and table size after HWP-to-DOCX saving.

Which pages should receive the closest review?
Start with pages containing equations, proofing marks, form controls, complex or merged tables, charts, drawings, special font effects, and unusual paragraph spacing or borders. These are named compatibility risk areas by Hancom.

Will HWP compression and automatic backups apply to the DOCX?
No. Hancom says Compress and Save is dedicated to HWP and does not apply to DOCX, and saving DOCX does not create the HWP backup file. Keep named source copies.

Should the original HWP be deleted after Word edits begin?
No. Retain it as the conversion source and visual reference. Once DOCX passes review, choose one editable working copy to avoid diverging untracked changes between formats.
