Captions are Essential for Modern Viewers

Over 80% of videos on social platforms are watched on mute. Without captions, you are losing a massive portion of your potential audience before they even hear your first words.

Our SRT builder allows you to take any transcript and turn it into professional, timed subtitles. Native YouTube captions (SRT files) also help with SEO as Google indexes the text within your video.

How to use:

  1. Paste your full video transcript into the text box.
  2. Ensure each new line corresponds to a new caption segment.
  3. Set the Seconds / caption (usually 3-4s is best).
  4. Click Generate SRT and download your file.
