Why Word Documents Lose Formatting
Word uses system-installed fonts. If your document uses a font the recipient does not have, Word substitutes the closest match — which changes line breaks, spacing, and page layout. Different versions of Word also handle table spacing and image placement differently. PDF embeds the fonts and renders the page as a fixed image-like representation. There is nothing to substitute and nothing to shift.
When to Convert Word to PDF
Final documents sent externally: resumes, proposals, reports, and contracts should be PDF before they leave your hands. Application portals: most job and government portals require PDF format. Archiving: PDFs are better long-term archives because they do not depend on software compatibility. Keep the Word source file for editing. Convert to PDF only for the final version you share.
The Best Way to Convert Word to PDF
Use Word itself: File > Save As (or Export) and choose PDF. Word is the only program that knows exactly how it laid your document out, so its own export is the most faithful result available, it is free, and the file never leaves your computer. On a Mac, Pages and the system Print dialog both offer Save as PDF. In Google Docs use File > Download > PDF Document. LibreOffice Writer has a direct Export as PDF button. ToolMint does not offer a Word to PDF converter. Every browser-based approach we tested discarded page size, margins, columns and font choices, which is precisely what a Word export needs to preserve.
What Gets Preserved and What Does Not
Preserved: text formatting (bold, italic, size), paragraph spacing, images, tables, headers and footers, page margins, and most list formatting. May change: advanced Word features like tracked changes, comments, form fields, and complex SmartArt may render differently. Macros do not transfer to PDF.
After Converting: Check Before Sending
Open the converted PDF and scan through it before sending. Check that page breaks fall in the right places, images are not cropped or stretched, and table borders are intact. If something looks wrong, return to the Word document, simplify the problematic section, and convert again. Common problems include wide tables that overflow the page margin and images with tight text wrapping.
