Made for real video
When you need VTT instead of SRT
WebVTT is the W3C standard the HTML5 <track> element requires — if you're adding subtitles to a website video, a documentation portal, or most LMS platforms, they want .vtt. Video platforms and desktop editors, on the other hand, usually prefer .srt. Same content, different wrapper.
This converter handles the details that trip up hand-editing: timestamp punctuation, the required header, preserving multi-line cues, and UTF-8 output so Hindi, Tamil, or any non-Latin script survives intact. Need to go the other way? Use the VTT to SRT converter.

Frequently asked questions
Is my subtitle file uploaded to a server?
No. The conversion runs in JavaScript in your browser tab. The file never leaves your device.
Is this really free?
Yes, completely — no account, no watermark, no limits. If you also need to generate subtitles from a video, that's what watchFIWN's free plan is for.
Will my Hindi/Tamil/Telugu subtitles convert correctly?
Yes — the converter reads and writes UTF-8, so all scripts pass through unchanged.
What actually differs between the formats?
VTT starts with a WEBVTT header, uses dots in timestamps where SRT uses commas, and supports optional styling and positioning that SRT lacks.
