What you get

A WebVTT file that just works in HTML5 video.

Spec-compliant VTT

WEBVTT header, period-separated timing (hh:mm:ss.ms), blank lines between cues, optional cue identifiers. Validates against W3C WebVTT spec — passes the FFmpeg and YouTube native upload checks.

Cue styling and positioning

Optional cue settings — line, position, align, vertical — plus inline styling tags. Place a speaker name top-left, a translation bottom-center, a chapter marker mid-screen.

Word-level timing

Each cue is built from word-level timestamps, not whole-line guesses. Captions snap to the exact word — required for karaoke-style highlight rendering and accurate seeking.

Drop into a track element

Paste the file URL into <track src='captions.vtt' kind='subtitles'> and the browser renders captions natively. Works in Safari, Chrome, Firefox, Edge — no JavaScript player library required.

VTT vs SRT

When to use VTT instead of SRT.

✗ An SRT pasted into HTML5

Some browsers tolerate it, most don't. Comma timing isn't VTT-spec; styling is unsupported; positioning is impossible. Works in VLC, breaks in <track>.

Comma-separated timing — not VTT spec
No cue styling support
No positioning, alignment, or vertical text
Inconsistent browser rendering
No metadata or chapter cues

FAQ

WebVTT generator questions, answered.

What's the difference between WebVTT and SRT?

WebVTT (.vtt) is the HTML5 standard — period-separated timing (00:00:01.200), supports cue styling, positioning, and metadata. SRT (.srt) is older, simpler — comma timing (00:00:01,200), no styling. Use VTT for HTML5 <track>, YouTube native upload, and styled captions. Use SRT for editors like Premiere, Final Cut, and Resolve.

Does YouTube accept VTT?

Yes. YouTube Studio's caption upload accepts both VTT and SRT. VTT is preferred when you need cue styling or chapter cues; SRT is fine when you just need plain captions.

Can I style the captions?

Yes. WebVTT supports cue settings (line, position, align, vertical) plus inline styling tags (<b>, <i>, <c.classname>) and optional CSS via ::cue pseudo-element. Our exports include style hooks; you write the CSS in your player. Branded burn-in styling is a paid unlock.

Which players support styled VTT?

Native HTML5 <video> with <track kind='subtitles'> in Safari, Chrome, Firefox, Edge. Video.js and Plyr render VTT styling. YouTube renders most cue settings but ignores ::cue CSS. Older players (jwplayer 6, flowplayer) may downgrade to plain text.

How accurate is the timing?

Word-level timing is typically within 50–100ms of the audio truth on clean recordings. Heavy background music, overlapping speech, or thick accents widen the window. Edit individual cues in our editor before exporting if needed.

Is the file stored anywhere?

Files live in your private library for 365 days; you can delete any item from your account settings. Your audio is never used to train AI.
