Subtitle Burner: Permanently Hardcode Captions to Video

Permanently burn SRT subtitles into your video files using our proprietary browser-based core.

Adding subtitles to your videos is essential for accessibility and social media engagement. However, "soft" subtitles can be turned off or lost during sharing. Our Subtitle Burner permanently hardcodes captions directly into the video frames, ensuring your message is always visible.

Using our proprietary browser-based core, you can process your files locally without worrying about server queues or data privacy.

Why burn subtitles into your video?

  • Guaranteed Visibility: Hardcoded captions can't be toggled off by the viewer or stripped by social media platforms.
  • Better Engagement: Many users watch videos with sound off. Subtitles keep them hooked.
  • Universal Compatibility: Works on every device and player since the text is part of the image.

Fast Workflow

  1. Upload your video file (MP4, MOV, etc.).
  2. Upload your matching .srt subtitle file.
  3. Preview the caption placement and styling.
  4. Our core burns the subtitles into the footage locally.
  5. Download your finished video.

Pro Tips

  • Check Timing: Ensure your SRT file matches the video's frame rate to avoid subtitle drift.
  • Font Clarity: Choose a font and color that stands out against your background. White text with a black outline or shadow is usually safest.
  • Safe Areas: Keep subtitles away from the very bottom to avoid being cut off by UI elements on TikTok or Instagram.

Checklist

  • Video and SRT file are ready.
  • Subtitle text is legible and properly styled.
  • Processing happens in-browser for maximum privacy.
  • Timing is verified in the preview before final download.
