Convert Word to PDF Without Losing Formatting

You spend an afternoon on a CV, export it to PDF, open the file, and the second page now contains a single orphaned line that was not there before. Or a heading has shifted font. Or the logo has moved three centimetres left.

The document did not change. What changed is that the PDF had to make its own decisions about things Word had left unresolved — and nearly every one of those decisions traces back to fonts.

Why the layout moves

Fonts that are not embedded

This is the dominant cause, and the mechanism is worth understanding because it explains almost everything else.

A PDF can either embed a font — storing the actual typeface inside the file — or reference it by name and hope the viewer has it. If it references a font the viewer does not have, the viewer substitutes the closest available match.

Substituted fonts have different character widths. Slightly wider characters mean a line that fitted now wraps. One extra line pushes the next paragraph down. A paragraph pushed down crosses a page boundary. One missing font can reflow an entire document.

This is why it works on your machine and breaks on someone else’s — you have the font installed, so your PDF reader shows it correctly even when it is not embedded.

Different default printer or page setup

Word lays out pages according to the current printer driver’s paper size and printable margins. Open the same document on a machine with a different default printer, or with no printer installed, and the usable text area changes slightly. Text reflows. Page breaks move.

This is why a document can look different on two computers before any PDF is involved.

Images that are anchored, not placed

A Word image with text wrapping is anchored to a paragraph. It is not at a fixed position on the page — it is “near this paragraph”. When text reflows for any reason, the anchor moves and the image goes with it, sometimes to the next page entirely.

Linked rather than embedded content

A chart linked from Excel, a picture inserted with Link to File, or an OLE object referencing another document all depend on the source being reachable. If it is not, you get a placeholder box or a stale version frozen at last update.

Features with no PDF equivalent

Some things simply do not survive the conversion:

Embed the fonts

The single highest-value fix, and it takes ten seconds.

1. File → Options → Save.
2. Tick Embed fonts in the file.
3. Tick Do not embed common system fonts — these are present everywhere and embedding them only inflates the file.
4. Leave Embed only the characters used in the document unticked if the document will be edited further; tick it if it is final, as it produces a smaller file.
5. Save the Word document, then export.

Two limitations to be aware of. Some commercial fonts carry licence restrictions that prevent embedding, and Word will silently skip those — if a font keeps substituting after you have ticked the box, the licence is the likely reason. And on macOS, Word’s font embedding support has historically been less complete than on Windows.

The safe alternative: use fonts that are genuinely universal. Calibri, Cambria, Arial, Times New Roman, Georgia and Verdana are present on effectively every Windows and Mac machine. A CV in Arial will never substitute.

Save As PDF, not Print to PDF

Both produce a PDF. They produce very different PDFs.

Use File → Save As → PDF (or File → Export → Create PDF/XPS) in almost every case. Print to PDF is a fallback for when Save As produces something broken, and it costs you searchable text, working links and the document outline.

The options that matter in Save As

Click Options in the Save As dialog:

• Document structure tags for accessibility — leave this on. It costs nothing and makes the PDF usable with screen readers.
• Create bookmarks using Headings — turn this on for anything longer than a few pages. It generates a navigable outline from your heading styles.
• Document properties — this includes your name and the document metadata. Untick it if you do not want that travelling with the file.
• Comments / Markup — off unless you specifically want them visible.

And the size setting, directly above Options:

• Standard (publishing online and printing) — keeps images at high resolution.
• Minimum size (publishing online) — downsamples images. Use this for anything being emailed or uploaded.

Keeping the file size sane

A Word document of 2MB routinely exports to a 15MB PDF, and the reason is images.

Delete cropped areas first. Cropping an image in Word hides the cropped portion but keeps storing it. A photo cropped to a tenth of its frame still carries every original pixel into the PDF. Select the image, go to Picture Format → Compress Pictures, tick Delete cropped areas of pictures, choose a resolution, and apply to all images.

Be clear that this is irreversible — once the cropped areas are gone you cannot re-crop outward. Save a copy of the document first if the crops are not final.

Choose a sensible target resolution in that same dialog. 150 ppi is right for on-screen documents, 220 ppi for a document that will be printed on an office printer. 330 ppi is for commercial printing and almost nobody needs it.

Then export with Minimum size. If the result is still too large, our PDF compressor will downsample further — though re-exporting from Word with better settings always beats compressing afterwards, because the images are resized once from the original rather than re-encoded from already-compressed versions. The reasoning is in why is my PDF so large and what will actually shrink it.

Converting without Word

• Google Docs — upload the .docx, open it, then File → Download → PDF. Expect minor layout differences, because Docs re-flows the document with its own layout engine rather than Word’s. Complex documents shift noticeably.
• LibreOffice Writer — free, offline, and File → Export as PDF gives you genuine control including font embedding and image resolution. Its .docx layout rendering is close but not identical to Word’s.
• Word mobile / Word on the web — both export to PDF and both are more faithful than third-party converters, since they use Microsoft’s own layout engine.
• Online converters — they work, but a Word document is often a CV, a contract or a report containing personal information, and uploading it to an unknown server is a decision worth making consciously.

Check the result before you send it

Formatting damage is almost always visible and almost never noticed, because people export and attach without opening the PDF.

1. Open the PDF, not the Word file. Keep both open side by side.
2. Compare page breaks. If page 2 now starts somewhere different, a font substituted or the layout reflowed.
3. Check the fonts list. In Acrobat Reader, File → Properties → Fonts. Every entry should say Embedded or Embedded Subset. Anything else will substitute on someone else’s machine.
4. Click a few hyperlinks. If none work, you used Print to PDF.
5. Check images and tables. Look for images that have jumped position and tables that have split across a page break mid-row.
6. Look at the last page. Orphaned single lines pushed onto a new page are the classic symptom of reflow.
7. Open it on a different device if the document matters. That is the test that catches missing fonts, because your own machine has them all.

What not to do

• Do not rely on “it looks fine on my computer.” Your machine has your fonts. That is precisely the condition under which a missing-font problem is invisible.
• Do not use Print to PDF by habit. It silently discards searchable text, hyperlinks and bookmarks for no benefit in almost every case.
• Do not export with tracked changes showing. Set the view to No Markup before exporting, or you will send a document with every edit visible.
• Do not rename a .docx to .pdf. It does not convert anything and produces a file nobody can open.
• Do not use decorative or purchased fonts on documents going to strangers unless you have confirmed they embed. A CV in a substituted font looks worse than one in Arial.
• Do not fix layout problems by editing the PDF. Fix them in the Word document and re-export. PDF editing is fragile and the next export will undo your work.
