What are subtitles?

Spoken words shown as text on screen in a video.

Many people watch with the sound off; subtitles keep the message clear. They improve accessibility and raise watch time.

Instagram, TikTok and YouTube offer auto-captions, but check them for mistakes. Keep subtitles inside the safe zone.
