What "free online" should actually mean
A lot of tools that say "free online" gate the useful part behind a signup form or limit you to one conversion before asking for payment. PrivaPDF is free with no daily limit, no account, no email capture, and no watermark added to the output — the PDF to Word conversion itself runs entirely in your browser tab.
Because there's no upload step, it's also faster than most "free online" converters in practice — no waiting for your file to travel to a server and the result to travel back.
