Word to PDF: When and Why You Should Convert
The problem with sending Word files
Open the same DOCX on two different computers and you may see two different documents. One computer has the font, the other substitutes it. Page breaks shift. Spacing changes. PDF exists to solve this: it locks the layout so it renders consistently everywhere.
When PDF is the right choice
Resumes, contracts, invoices, anything meant to be read rather than edited. PDF says "this is the final version." Sending a Word file for a contract invites confusion about which version is current. The trade-off is that PDFs are harder to edit — which is often exactly what you want.
What can still change
The most common surprise is a font substitution that shifts text enough to push a line onto a new page. This almost always comes from a font that was not available on the conversion system. Quick check: look at the last page after converting. That is where unexpected page breaks show up first.
If someone needs to review and edit the document, send the Word file. If they just need to read it, send the PDF. Sending both covers every situation.
