How to convert Word to PDF without losing fonts or layout formatting

Converting a Microsoft Word (DOCX) document to PDF sounds simple, yet millions of people end up with misaligned tables, shifted margins, substituted fonts and broken page breaks. This happens because a Word document reflows its text to fit, while a PDF fixes every element to an exact spot on the page. Converting with Word to PDF in the browser saves you the trip through someone else’s server.

Why Word Documents Shift Between Devices

When you open a DOCX file on another computer, Word works out paragraph heights and line breaks again, based on three things:

• Installed System Fonts: If a document uses a paid or custom font that the other computer does not have, Word quietly swaps in a common fallback font (like Arial or Calibri). The letters have different widths, so the lines break in different places.
• Printer Driver Metrics: Word's layout engine asks the default printer driver for its margin limits. Change the printer and single words can spill onto new lines.
• Platform-Specific Rendering Differences: Word for Windows and Word for macOS use different methods for font smoothing and for rounding line heights.

How to Ensure 100% Faithful Word to PDF Conversion

1. Embed Fonts Inside the DOCX: Turn on "Embed fonts in the file" in Word's Options before saving (Microsoft explains the setting in its guide to embedding fonts).
2. Lock Table Dimensions: Set column widths in inches or millimetres, not percentages, so columns do not collapse when the page width changes.
3. Use Vector Elements for Logos: Use SVG or high-resolution PNG files for company letterheads, so logos do not turn blocky when the page is converted to pixels.
4. Export Directly to PDF/A: Use the ISO 19005 (PDF/A) standard for long-term archiving. It makes sure all fonts, colour profiles and metadata are stored inside the file itself.

Confidential Document Conversion in Your Browser

Sending business proposals, employee contracts or financial audits through a third-party web converter puts trade secrets at risk. With in-browser conversion, the document's OpenXML structure is read and turned into PDF drawing instructions without leaving your browser's memory. The same applies in reverse when you need PDF back to Word.
