SRT to VTT: convert subtitles for use on the web

VTT (WebVTT) is the subtitle format accepted by browsers’ video player. Open the SRT file and download the VTT: the WEBVTT header is added and the times go from comma to period. The conversion happens in the browser, without sending the file.

Reading review · 0 line(s) with warnings

Warnings help review long lines, fast reading, more than two lines, durations and overlaps. They are adjustable references, do not block export and may be intentional in dialogue.

The output uses the applied corrections.

Continue in the video editor or the text editor.

When this is useful

The browsers’ video tag uses subtitles in VTT.

Reuse a subtitle made for another program

Many editors export SRT, and the site asks for VTT.

Tips for a good result

  • The downloaded file takes the original’s name with the .vtt extension.
  • To remove italics and bold from the subtitles, use “Remove style tags” in the Adjust timing tab.
  • For the opposite conversion, use the VTT to SRT page.

What this tool does not do

  • Italic and bold tags (<i>, <b>) are kept, unless you choose to remove them.
  • VTT-specific position and alignment do not exist in SRT, so none of that is created in the conversion.
  • Subtitle files of up to 5 MB; ZIP of up to 256 MB; video of up to 2 GB.
  • Everything happens in the browser: the file is not sent. The only exception is the optional translation, which sends only the text of the lines.

Frequently asked questions

Do the times change?
No. The intervals are the same; only the separator of the milliseconds changes, from comma to period.
Is the file sent to any server?
No. The conversion is done in your browser.
