Convert HWP to PDF Online for Free

HWP is a Hancom working document, not just Korean text in a file

An .hwp file is the native document format used by Hancom’s Hwp word processor. It can contain the ordinary features expected in a full word-processing document: formatted text, page and paragraph settings, tables, pictures, drawing objects, charts, equations, headers, footers, notes, fields, and document-security settings. A document may contain Hangul, but HWP is not limited to Korean-language text; the important conversion issue is that it uses Hancom’s document model and feature set rather than Microsoft Word’s or PDF’s fixed-page model.

Hancom documents several HWP-specific storage choices that matter before export. Its File Options say that “Compress and Save” is dedicated to HWP and does not apply when saving as DOCX. The same options can save a 24 KB preview image to make the Open dialog preview faster. A document password can be set only while saving as HWP or an HWP template, not when saving to other listed formats. These facts explain why a PDF conversion is not a simple re-labeling of the original: it produces a separate rendered copy with different storage, security, and editing behavior.

Keep the HWP source even after the PDF looks correct. The HWP holds the editable objects and the settings needed to make later corrections. The PDF is the shareable or print-oriented representation. If a page number, date, image, or clause changes, update the HWP, verify it in Hancom, and make a new PDF. Editing a fixed PDF afterward does not repair the source that will be used for the next revision.

Hancom renders the document into a preservation-oriented PDF result

PDF stores the instructions needed to draw a finished page, while HWP stores editable word-processing content and layout rules. During HWP-to-PDF export, Hancom resolves the current page flow, font choices, object positions, headers, footers, and fields, then saves the displayed result as pages. Hancom’s current Save as PDF documentation says the export is saved as PDF/A-1b among the PDF properties. PDF/A-1b is a preservation-oriented PDF conformance level, not a promise that the source document has been made editable, modernized, or automatically accessible.

Font handling deserves special attention. Hancom states that fonts may be included only when their providers allow inclusion. When permitted, included fonts are not replaced during reading or printing, and the exporter can include all fonts or just a subset of the characters used. Subsetting can reduce output size but means the PDF contains only the glyphs required by that export. A missing or non-embeddable font can change the result before or during export; increasing PDF quality cannot restore a font that the renderer could not use.

The conversion records the rendered state, not every editable HWP feature. A table remains visible as part of a fixed page rather than an HWP table that can grow naturally. An equation may be shown correctly but is no longer a native HWP equation editor object. A password set on HWP does not automatically become a generic document-password rule in PDF simply because the pages were exported. Inspect the delivered file rather than assuming the source’s edit restrictions, object behavior, and recovery settings crossed formats.

Fixed PDF pages provide real gains and deliberate losses

• Readers do not need the HWP editor: a PDF viewer can show the exported pages without understanding Hancom’s editable document objects.
• Hancom writes PDF/A-1b output: that can support a preservation requirement, but it does not replace the HWP master or a required validation workflow.
• Permitted fonts can be included or subset: this can prevent font substitution in the finished PDF, subject to the font provider’s embedding rights.
• HWP editing features stop being live: tables, fields, equations, charts, and drawing objects are represented as the rendered result, not native HWP controls.
• Document password rules change: Hancom allows passwords for HWP and HWT save types, not automatically for other save types, so check PDF protection requirements separately.
• Source recovery remains in HWP: HWP auto-save, backups, and HWP-specific compression are not a substitute for retaining the original after export.

Use PDF when the requirement is a stable reading, printing, submission, or preservation copy. Use HWP when a person must continue editing the actual document objects. For a multi-party review, the practical pair is often a checked PDF for the page reference plus the HWP retained by the editor responsible for future changes.

Compatibility is broad for viewing but specific for preparation

Hancom Hwp provides a direct File, Save/Send To, Save as PDF path rather than requiring a virtual printer. Its documentation says the status bar displays progress during conversion. On Hancom Office Mobile, the Hwp File menu also includes Save as PDF, alongside regular save and distribution-document options. These facts make PDF the natural compatibility target when recipients need the rendered document rather than HWP editing, but they do not remove the need to check output created by the version and device actually used.

An HWP file can contain objects that are visually sensitive: tables, drawings, pictures, charts, equations, notes, and page numbering. The source viewer must show these correctly before export. If a source opened in a different program already substitutes fonts or flattens objects, the PDF will record that altered version. Open and review in Hancom where possible, compare dense pages to the output, and check in an independent PDF viewer before releasing the file.

Text correctness is more than whether letters appear. Review Hangul and every other script at normal zoom, copy a sample into a Unicode-aware text editor if selectable text matters, and inspect mathematical symbols and special punctuation. A font subset may render the intended page well while the font-license or software setting changes the available embedded glyphs. The delivered PDF should be checked in the same way it will be consumed: on screen, printed, submitted, or archived.

Export defects usually start in an identifiable HWP condition

Text changes width, clips, or pushes a footer to another page. Check the HWP source on the exporting system first. A font that is absent, restricted from embedding, or substituted by the renderer can alter line width. Also inspect paper size, margins, paragraph spacing, and table dimensions. Hancom’s font documentation makes embedding conditional on provider permission, so the reliable repair is an approved available font or an adjusted source layout, followed by another export.

The PDF shows an old date, page number, or cross-reference. The exporter captured the displayed value at the time it rendered the HWP. Update and verify relevant fields in the source before saving as PDF. Do not attempt to patch the fixed output if the next revision will use the same stale HWP field; correct the source and re-export so the document lineage remains clear.

A chart, equation, picture, or table looks different from the source. Compare it first in Hwp itself. An object that displays incorrectly before export is a source or compatibility problem, while an object that changes only in PDF needs a focused export test. Replace unsupported artwork with a reliable rendered asset where necessary and check all pages containing complex objects. A one-page spot check is not enough for a document whose appendices use different object types.

A protected HWP becomes an easily viewable PDF. This is a format and delivery change, not proof that protection survived. Hancom limits document-password saving to HWP or HWT in its Save As documentation. Determine separately whether the PDF needs a password, rights restriction, or a secure delivery channel; an HWP password should not be treated as a property that automatically travels into the new format.

HWP and PDF preserve different evidence

Questions before issuing an HWP document as PDF

Does Hancom create an ordinary PDF or a preservation profile?
Hancom’s Save as PDF documentation identifies the output as PDF/A-1b among its PDF properties. Keep the HWP source and use any required archive validation process in addition to export.

Will the recipient need Hancom Hwp to view the PDF?
No. The PDF is a rendered output intended for PDF viewers. Hancom is needed for the original editable HWP workflow, not ordinary PDF reading.

Why did text reflow after PDF export?
Check the source page settings and whether a required font was available and permitted for inclusion. Font substitution or different metrics can change line widths before the PDF is made.

Does an HWP document password automatically protect the PDF?
Do not assume so. Hancom documents password saving for HWP and HWT formats; assess PDF protection and delivery requirements as a separate step.
