Online Tool for Adding Subtitles and Captions to Video

Permanently embed subtitles or closed captions into any video file directly in your browser. Upload a video together with an SRT subtitle file, or type subtitles manually with precise start and stop times. Customize the subtitle appearance by choosing the font, size, text color, and outline color to match your creative vision.

This tool hard-burns subtitles into the video frames, meaning they become a permanent part of the video and will display on any player or platform - ideal for social media posts, presentations, and accessibility compliance. Supports MP4, WebM, MOV, AVI, MKV, and many other video formats up to 200MB.

You can also upload an existing .srt subtitle file to preview and edit it before burning the captions into your video. No software installation or registration required - completely free with no watermarks.

How to add subtitles to video

  1. Upload your video file using the form above (drag and drop, browse, or paste a URL).
  2. Choose one of two subtitle methods:
    • Upload an SRT file — select a ready-made .srt subtitle file and it will be parsed automatically.
    • Enter subtitles manually — type each line of text and set start/stop timestamps. Use the "Use current position" button while playing the video to set precise timing.
  3. Customize the appearance — adjust font, size, text color, outline color, and background opacity to match your video style.
  4. Click "Add subtitles!" to burn the captions into the video.
  5. Preview the result and download the final video with permanently embedded subtitles.
