Convert to PDF guide
Word to PDF Without Changing the Formatting
Updated
Short answer: Drop the DOCX into Word to PDF, then compare page count and the last line of each page with the original before you send it.
CVs, applications, assignments and contracts are usually sent as PDF precisely so the layout can't change. The conversion is where it can go wrong, and knowing why helps you catch it.
Step by step
Step 1: In Word, note the page count and how the last page ends.
Step 2: Open Word to PDF and drop the DOC or DOCX file.

Step 4: If you need several documents in one file, such as a CV and a cover letter, merge them.

Why this works, and what to watch for
Almost every layout shift comes down to fonts. A Word document refers to fonts by name and usually doesn't contain them. If the converter has a font with different letter widths, every line wraps at a different word, paragraphs grow or shrink, and page breaks move. Word to PDF uses LibreOffice with fonts that are metric-compatible with Calibri, Cambria, Arial and Times New Roman, meaning each letter takes exactly the same width, so lines break where they did in Word.
Custom and decorative fonts are the risk. If your document uses a font that isn't one of the common Office fonts, it may be replaced with a similar-looking one with different widths. Two fixes work: embed fonts in the document (in Word, File → Options → Save → Embed fonts in the file) before converting, or switch headings to a standard font.
Other things to check. Text boxes and shapes anchored to paragraphs can move slightly if a paragraph above them changes height. Very complex tables with merged cells across page breaks are worth a look. Fields such as tables of contents and cross-references are converted as they were last updated, so update them in Word first (select all, then F9 on Windows).
Tracked changes and comments are a common surprise. If the document has unaccepted revisions, accept or reject them before converting so the PDF shows the clean final text rather than your edits.
The PDF has real, selectable text, which is what applicant tracking systems and plagiarism checkers need. It's also never watermarked: free conversions come out clean.
