Stop manually timing captions frame by frame. Upload your audio and get perfectly synced WebVTT subtitles fast, ready for web video players and YouTube workflows.
WebVTT (Web Video Text Tracks) is the modern standard for web video subtitles.
Each subtitle has a timestamp range and text content. VTT uses periods for milliseconds.
Generate perfectly timed WebVTT subtitles in three simple steps.
Drop your MP3 file. Our AI analyzes the audio to detect speech and timing.
AI transcribes and timestamps every word automatically. Review and fine-tune anything that needs adjusting.
Download your VTT file. Also export as SRT, LRC, or other formats if needed.
Choose the right format for your project.
| Format | Best For | Supported |
|---|---|---|
| VTT | Web videos, YouTube, HTML5 players | |
| SRT | Video editors, media players, legacy support | |
| LRC | Music players, karaoke, streaming |
Both are subtitle formats with timestamps. VTT (WebVTT) is the modern web standard — it's what YouTube and HTML5 video players use natively. SRT is older but still widely supported by video editors and media players. LyricTime exports both, so you're covered either way.
Upload VTT directly to YouTube for perfectly synced captions on your videos.
VTT is the native format for HTML5 video — just add a track element to your player.
Upload VTT captions to professional video hosting platforms.

WebVTT is more powerful than SRT—it supports styling, positioning, and metadata. Here's how it works:
VTT is the native subtitle format for HTML5 video. Adding captions to your web videos is straightforward.
Use "subtitles" for translations, "captions" for same-language + sound effects, or "metadata" for non-visible data.
Add "default" to show captions automatically. Without it, users must manually enable them in the player.
Add multiple track elements with different srclang values. Users can switch between them in supported players.
