How to Prevent Font Corruption — Keep Documents Looking Right When You Send Them

Jun 23, 2026

You spent time formatting a proposal, hit send — and got a reply: "The layout looks all messed up on my end." Your screen showed it perfectly, but on the recipient's PC the fonts changed and the line spacing fell apart. Here's why that happens and the fastest way to fix it for good.

Why Fonts Break

The cause is straightforward. When you use a font that is only installed on your PC, a recipient's computer that lacks that font substitutes the closest one it can find. Because every font has slightly different character widths and line heights, the substitution shifts your entire layout.

  • Designer or premium fonts — Fonts you purchased or downloaded separately almost certainly aren't on your recipient's machine.
  • Company-specific fonts — Fonts distributed internally by your organisation won't exist on external partners' PCs.
  • OS font differences — A document created on a Mac may render differently on Windows because each OS ships with different default fonts.

A single font swap can push text boxes out of place, clip text inside table cells, and shift page breaks — a costly problem when sending contracts or client-facing proposals.

The Best Fix — Convert to PDF

The most reliable solution is to convert your document to PDF before sending. PDF embeds font data directly inside the file, so the recipient's PC reproduces your document pixel-for-pixel regardless of what fonts are installed locally.

  • Works for every major office format: HWP, Word (DOCX), Excel (XLSX), and PowerPoint (PPTX).
  • Recipients can view it in any browser or PDF reader and see exactly what you see.
  • Keep the original editable file for yourself; share only the PDF as the final version.

This is why PDF has become the de-facto standard for emailing contracts, proposals, and reports — the layout is guaranteed.

Secondary Methods — Embed Fonts & Use Standard Fonts

If you must share the original editable file, use these approaches alongside PDF export.

① Embed Fonts in Word

In Microsoft Word, go to File → Save As → Tools → Save Options and check "Embed fonts in the file." This bundles the font data inside the .docx so recipients see the correct typeface even without installing it. Note that file size increases.

② Stick to Standard Fonts

Using fonts that ship with Windows by default eliminates the problem entirely. Safe choices for Korean-language documents include:

FontNotes
Malgun Gothic (맑은 고딕)Windows default Korean sans-serif; clean and readable
Batang (바탕)Serif style; common in official documents and contracts
Dotum (돋움)Gothic style with strong on-screen legibility
Gulim (굴림)Softer rounded Gothic; widely available

If your document requires a custom typeface for branding, use it freely — just export to PDF before distribution.

How to Export PDF — One Line Per App

  • Hangul / HWP — File → Save as PDF (font embedding included)

FAQ

Q. Does converting to PDF really prevent all font issues?
Yes. PDF embeds font data inside the file, so the recipient's display matches yours exactly — regardless of what fonts they have installed. This applies to Word, HWP, Excel, and PowerPoint documents alike.

Q. If I embed fonts in Word, do I still need to convert to PDF?
Embedding fonts in a .docx helps when the recipient must edit the file. However, file size increases and behaviour can vary across Word versions. For final deliverables — especially contracts or proposals — PDF is safer and universally consistent.

Q. Does saving a Korean HWP file as PDF preserve the fonts?
Yes. The Hangul word processor's built-in "Save as PDF" function includes font embedding. To convert HWP without installing the Hangul application, use the free HWP → PDF Converter.

Q. Are standard fonts always safe to use?
Fonts like Malgun Gothic, Batang, and Dotum ship with Windows and are present on the vast majority of PCs. Edge cases — such as Mac recipients or very old systems — can still cause substitution. For documents where layout precision matters, pair standard fonts with a PDF export to be completely sure.
