How to Convert Word to PDF Without Losing Formatting

You spend an hour perfecting your document in Word. Fonts are just right. Margins are perfect. Then you convert to PDF and text has moved, a font has changed and a table has fallen apart.

The short answer: the converter that drew the original layout is the one that keeps it. Word's own PDF export is the most faithful option, and every other route, including browser converters like ours, rebuilds the page and loses something on the way. This guide covers which settings matter in Word, what each alternative drops, and exactly what our free converter keeps.

Why Does Formatting Change When You Convert Word to PDF?

Word flows text dynamically: line breaks depend on the fonts installed, the printer driver and the page setup. A PDF fixes every character at an exact position. Any converter that is not Word has to re-run that layout itself, and small differences add up:

• Font substitution: if the converter lacks your font, it swaps in a similar one with different letter widths, so lines break in new places.
• Missing characters: a substitute font may not contain every letter of your language. Those letters come out as blanks or symbols (see the test below).
• Complex tables: merged cells and auto-fit columns are re-measured and often shift.
• Floating objects: images and text boxes anchored to a paragraph can move when that paragraph moves.

What Is the Most Reliable Way to Keep Formatting?

Export from Word itself. On Windows (Word 2010 and later):

1. Go to File → Save As and pick "PDF (*.pdf)" as the type.
2. Leave "Optimize for" on Standard (publishing online and printing). "Minimum size" lowers image quality.
3. Click Options and tick "Create bookmarks using Headings" and "Document structure tags for accessibility". Tick "PDF/A compliant" if the PDF is for long-term archiving or an official portal that asks for it.
4. Save.

On a Mac, File → Save As → File Format: PDF offers two choices. "Best for printing" is created on your computer. "Best for electronic distribution and accessibility" produces a tagged PDF but, as Word notes next to the option, uses a Microsoft online service, so the document is sent to Microsoft to be converted. For a contract or ID document, pick "Best for printing".

What Should You Check Before Converting?

1. Embed your fonts

In Word for Windows, File → Options → Save → tick "Embed fonts in the file". This matters most when you send the .docx to someone else to convert, because their machine may not have your fonts. It increases file size.

2. Use fonts that exist everywhere

Arial, Times New Roman, Calibri and Georgia are on virtually every system. Decorative fonts are where substitution starts.

3. Set page breaks yourself

Insert manual page breaks (Ctrl+Enter) where a page must end, so a slightly different line height cannot push a heading to the bottom of the previous page.

4. Simplify tables

• Avoid merged cells where you can
• Set fixed column widths instead of auto-fit
• Give cells enough padding that a wider font does not wrap

How Do the Alternatives Compare?

Print to PDF is a good fallback when Save As misbehaves, because it captures exactly what would print. The cost is that it produces a flat document: clickable links, heading bookmarks and accessibility tags are gone.

What Does the DocuTools Converter Keep and Drop?

Our Word to PDF tool runs in your browser and never uploads the file. To do that it reads the .docx structure with mammoth.js and redraws the text with jsPDF, which is a different trade-off from Word's export. Here is what that means in practice:

• Kept: all body text, paragraphs, headings 1–3 (set in larger bold type), bold and italic text, and bulleted and numbered lists.
• Changed: every font becomes Helvetica at 11 pt on A4 with 20 mm margins. Bold and italic runs start on their own line instead of staying inside the sentence. Tables become lines of text with cells separated by " | ".
• Dropped: images, colours, text alignment, headers and footers, and Word's own page breaks.

That makes it a good fit for text-first documents such as letters, notes and simple reports when you are on a computer without Word. It is the wrong tool for a designed CV, a brochure or anything with a table you need to keep as a grid.

Which Languages Break in Browser Converters?

Many browser-based converters, ours included, draw text with the standard PDF fonts because embedding a full font file in a web page is heavy. Those fonts only cover Western European characters. We tested this by writing sample text with jsPDF's built-in Helvetica and reading it back out of the resulting PDF:

If your document is in one of the affected languages, use Word, LibreOffice or Google Docs, which embed fonts that contain those letters. Whatever converter you use, search the finished PDF for a word with an accented letter: if search cannot find it, the character was not stored correctly.

The Bottom Line

Use Word's Save As PDF with "Standard" quality when layout matters, and Print to PDF if that fails and you do not need links. Use a browser converter for quick, private conversion of text-first documents in Western European languages, and always compare the PDF with the original page by page before sending anything important.
