SRT to VTT Converter
Upload an SRT subtitle file and get a WebVTT file in seconds — free, no account required.
FloxerFile converts SRT subtitle files to the WebVTT format used by HTML5 video players and modern streaming platforms. The conversion runs entirely as text parsing — no video re-encoding involved — so it completes instantly regardless of file size.

Download the WebVTT file directly to your device. Your file is never stored — it is deleted immediately after conversion.
Features
Pure text conversion
No video re-encoding involved — this is a straight text/timestamp reformat, instant regardless of the video's length.
Correct timestamp format
SRT's comma decimal separator (00:00:01,500) is converted to WebVTT's required period (00:00:01.500) — a common source of broken subtitles when done by hand.
Adds the required WEBVTT header
Every output file starts with the WEBVTT header line that WebVTT players require — missing it is a common cause of subtitles that silently fail to load.
Rejects malformed cues
Files with invalid timestamps or no valid cue blocks are rejected with a clear error instead of producing a broken .vtt.
Supported formats
SRT
SubRip subtitle format, the most common subtitle file format.
Output format: .vtt
Frequently asked questions
- What's actually different between SRT and VTT?
- The decimal separator in timestamps (comma vs. period), the required WEBVTT header line, and cue numbering, which SRT requires and VTT doesn't.
- Will my subtitle timing stay exactly the same?
- Yes — timestamps are parsed and re-emitted precisely, nothing is rounded or shifted.
- Why would I need WebVTT instead of SRT?
- HTML5 <track> elements and most web video players require WebVTT specifically — SRT isn't accepted directly in a browser.
- Is my subtitle file stored anywhere?
- Your subtitle file is parsed and converted entirely in server memory, then deleted immediately after download.
