What Does the Add Subtitles to Video Do?

The Add Subtitles tool burns captions directly into your video, so they display on every platform — even ones without subtitle support. Type or paste your subtitle text with timestamps, style the font and colors, and export an MP4 with permanent, great-looking captions.

Subtitled videos get watched longer: most social feeds play muted, and captions make content accessible to deaf and hard-of-hearing viewers. Creators use it for TikTok and Reels captions, teachers for lecture videos, and businesses for training material that works with the sound off.

How to Use It — Step by Step

  1. Upload your video file above.
  2. Add subtitle lines with start and end times.
  3. Style the text — font size, color, and position.
  4. Export the MP4 with burned-in subtitles — free, no watermark.

Popular Uses

  • Social videos: captions for TikTok, Reels, and Shorts watched on mute.
  • Courses: subtitle lectures for clarity and accessibility.
  • Business: training videos that work in noisy offices.
  • Translations: add translated captions to reach new audiences.

Private by Design

Like every tool here, the Add Subtitles to Video works 100% in your browser. Your files are processed on your own device and never uploaded to any server — which also means it is fast, private, and free to use.
