What does the converter strip out?

It removes the WEBVTT header line and any header metadata, plus NOTE, STYLE and REGION blocks, which have no SubRip equivalent. Cue positioning settings after the timestamps are also dropped because SubRip does not support them.

How are timestamps changed?

WebVTT uses a dot before milliseconds and may omit the hours field (00:04.000). The converter switches the dot to a comma and expands short timestamps to the full hh:mm:ss,ms form that SubRip requires.

What happens to voice and class tags?

WebVTT voice tags and class tags have no SubRip counterpart, so their wrappers are removed while the spoken text inside them is kept. Basic styling like italics passes through unchanged.

Does it renumber the cues?

Yes. SubRip requires a sequential numeric index above every cue, so the converter discards any WebVTT cue identifiers and renumbers from 1 in order.

No. The whole conversion happens in your browser. Your subtitle file is never sent to a server, so private or pre-release captions stay on your device.

WebVTT to SRT Converter

SubRip (.srt) is still the most widely supported subtitle format for desktop media players, encoders and editing tools, while WebVTT (.vtt) is what the web uses. If you’ve downloaded or generated captions as WebVTT and need them in SubRip, this converter rewrites the file cleanly.

How it works

WebVTT carries a few things SubRip doesn’t, so converting is mostly about removing them and reformatting the timestamps:

Drop the header and metadata. The leading WEBVTT line and any text up to the first blank line are skipped, along with NOTE (comments), STYLE (CSS) and REGION (layout) blocks, none of which exist in SubRip.
Read each cue’s timing line. WebVTT timestamps put a dot before the milliseconds and may leave out the hours field entirely — 00:04.000 means zero hours. The converter expands that to 00:00:04,000, switching the dot to a comma and padding the hours.
Discard cue settings. Positioning directives that can trail the timing line (for example line:90%) are removed, since SubRip has no place for them.
Clean the text. WebVTT voice tags and class-styling wrappers are stripped while the visible text inside is kept; ordinary styling such as italics passes through.
Renumber. SubRip requires a sequential index above each cue, so cues are numbered from 1 in order and any WebVTT identifiers are dropped.

Example

A WebVTT cue with a short timestamp and a cue setting:

intro
00:04.000 --> 00:08.200 line:90%
This line uses cue settings.

becomes clean SubRip:

1
00:00:04,000 --> 00:00:08,200
This line uses cue settings.

Notes

If the file doesn’t start with WEBVTT, the converter still attempts the conversion and warns you, which helps with slightly malformed exports.
Timing values are preserved exactly to the millisecond; only their formatting changes.
Everything runs in your browser, so your captions are never uploaded.
