  3. Press the button and download the video.

Good to know

  • Long lines are wrapped to fit; italic subtitles stay italic.
  • Subtitles early or late? Move them all with the "Move by" field, or fix the file with the Subtitle Time Shifter.
  • Burned-in subtitles can't be turned off. To keep them switchable, add the subtitle file to your video player instead.
  • It uses your browser's built-in video technology: best in current Chrome and Edge, and recent Safari and Firefox versions.

Frequently asked questions

Where do I get an SRT file?

From the person who made the video, from subtitle sites, or by writing one in a text editor. This site can't create subtitles from speech.

Is my video uploaded?

No. It is processed in your browser and never sent anywhere.
