VTT to SRT: convert subtitles for use in any player

SRT is the subtitle format most accepted by computer players, televisions and editors. Open the VTT file and download the SRT: the lines and times are kept, and what exists only in VTT is left out. The conversion happens in the browser, without sending the file.

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.

Tips for a good result

  • The downloaded file takes the original’s name with the .srt extension.
  • The blocks are numbered in order, starting from 1.

What this tool does not do

  • Comments (NOTE), position and alignment from the VTT do not carry over to the SRT: in the test, “position:50% align:center” and a NOTE line were left out.
  • Italic and bold tags (<i>, <b>) are kept, unless you choose to remove them.
  • 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.

Do I lose the lines?
No. All the lines and all the times are kept; only features exclusive to VTT, such as position and comments, are lost.
