FAQ

Can I convert VTT to SRT as well as SRT to VTT?

Yes. Select the existing file, choose SRT or VTT, and inspect the result. Use this same page for either direction; you do not need a separate converter.

What is the difference between SRT and VTT?

SRT is a common subtitle format for video editors and players. WebVTT starts with a WEBVTT header and is used for web video text tracks. Basic SRT timestamps use a comma before milliseconds; VTT uses a period.

Does converting subtitles translate their language?

No. Format conversion keeps the caption language. It does not translate text, transcribe speech, or create a dubbed video.

Does TXT to SRT automatically synchronize with my video?

No. Each non-empty TXT line becomes a three-second cue starting at zero. These are placeholder timings, not speech detection. Adjust and verify them in a subtitle editor before using them with a video.

Are my subtitle files uploaded, and do I need an account?

No account is needed. The file is read and converted in your browser, without uploading its contents for conversion.

Will every style, position, and subtitle feature be preserved?

Do not rely on this converter to preserve advanced styling, positioning, or all WebVTT features. Compare the downloaded file with the original. Keep a backup, and use a dedicated subtitle editor if captions are missing or timing changes.

SRT to VTT: compare the same two captions

This original example keeps the words and cue times. VTT adds the WEBVTT header and uses a period before milliseconds. Download either file to try the reverse conversion too.

What this subtitle converter does—and does not do

  • SRT and VTT conversion changes the file format, not the spoken or written language.
  • TXT export removes cue timings. TXT import assigns three seconds to each non-empty line; it does not align text to speech.
  • Keep the original file. Inspect the full download in your player or editor; the preview may be truncated.
  • Advanced WebVTT styling and positioning may not survive conversion. If captions are missing, use a subtitle editor instead of publishing an incomplete file.
