QUICK ANSWER
Is it possible to convert SRT to VTT?
Yes - SRT converts to VTT.

Subtitle Edit converts .srt to .vtt in a few clicks via File > Save As and selecting WebVTT from the format list. The only structural differences are a WEBVTT header line at the top and a period instead of a comma before milliseconds in timecodes - no subtitle content is lost.

Also to VTT: SCC · SBV · SUB

Why convert SRT to VTT?

HTML5 video players use the <track> element which requires WebVTT; SRT is not part of the HTML5 track specification. If you are adding subtitles to a web page or uploading to a platform that demands .vtt, you need to convert. The structural change is minimal because both formats represent the same timed cue data.

Quality & what to watch

  • No subtitle content is lost - every cue, timecode, and text line transfers intact; only the header line and the comma/period timecode separator change.
  • SRT inline tags (<b>, <i>, <u>) carry over into VTT, but some web players ignore or strip them - verify playback after converting if styling matters.
  • WebVTT supports cue positioning and alignment that SRT lacks; converting from SRT gives no positioning data, so all cues appear at the player's default position.

Frequently asked questions

What is the actual difference between SRT and VTT?
VTT adds a WEBVTT header line at the top and uses a period before milliseconds in timecodes instead of a comma; the cue text content is otherwise identical.
Can I convert SRT to VTT manually in a text editor?
Yes for small files: add WEBVTT as the first line, then replace every comma before milliseconds with a period using Find & Replace.
Will the subtitle timing change after conversion?
No - timecodes are preserved exactly; only the punctuation separating seconds from milliseconds changes.
Which web video players require VTT instead of SRT?
HTML5 <track> elements, video.js, and Plyr all require WebVTT; SRT is not supported by the HTML5 track specification.
