Why send a PDF instead of a Word file
Convert to PDF whenever the way a document looks must not change on someone else's computer. A resume, a signed letter, a contract or a formatted proposal can reflow unpredictably when opened in a different Word version or on a phone, and a recipient without Word may not open a .docx at all. A PDF locks the layout, embeds the fonts and prints identically everywhere. It is also the format most upload forms and application portals expect, which makes conversion a routine last step before sending anything important.
