What a PDF actually is

Say when a PDF is the right format and when it is the wrong one.

A Word document is a set of instructions. Your computer decides where the lines break, using the fonts and page size it happens to have.

That is why a document can look perfect on your screen and arrive at your bank with the address halfway down page two.

A PDF settles the argument. It records where every letter sits and carries the fonts along, so the page looks the same everywhere.

The cost of that stillness is editing. Changing text in a PDF is possible but awkward, because the file describes a finished page rather than a living draft.

What to remember

Try this

Take one letter or list you have already finished, use Export As or Save As PDF, then open the PDF and confirm the page looks identical to what you wrote.
