About this tool

Burn an SRT subtitle file permanently into a video. The subtitles become part of the picture and play on any device, including ones that don't support soft subs.

Features

  • Hardcodes SRT into the video
  • Style controls inherited from FFmpeg's subtitles filter
  • Works for social uploads where soft subs are stripped
  • Browser-only

How to use it

  1. Upload a video and an .srt file.
  2. Click Burn.
  3. Download the subtitled video.
🔒 100% private

Everything happens inside your browser using JavaScript and WebAssembly. Your files are never uploaded to a server, never stored, and never seen by us.

Frequently asked questions

Can I keep them as soft subs instead?

Burning is permanent. Use a container like MKV with a separate SRT track if you want toggleable subs.
