Professional captions in minutes

On LinkedIn, videos autoplay muted in the feed. Captions make your point clear in the first seconds and make your content accessible. HeyCaptions creates them automatically in a clean style that suits a professional audience – or a bolder look if you prefer.

Correct names and company terms in the Text tab before you download.

Burned-in captions or an SRT file

Burned-in captions show for everyone in the feed. When you post a video from a computer, LinkedIn also lets you attach an SRT file so viewers can turn captions on and off – you can download both from HeyCaptions.
