What is a .SRT file?

SRT (SubRip) is the most common subtitle format - a simple text file of timed captions. Read by VLC and virtually every media player.

Did you know
  • The SRT format comes from the SubRip subtitle-ripping tool released around 2000.
  • Each SRT entry has a fixed shape: a sequential number, a start and end timecode joined by an arrow, then the caption text and a blank line.
  • SRT timecodes use a comma before the milliseconds (00:01:23,456), a quirk that distinguishes them from the full stop used by many other formats.
  • The base format carries no styling, but players often honour a handful of inline HTML tags such as bold and italic embedded in the caption text.
  • A .SRT file is plain text, so you can open and edit it in any text editor.
