SRT to WebVTT FAQ

Quick answers for converting subtitle files, fixing caption timing, and choosing the right output format.

How do I convert SRT to WebVTT?

Upload an .srt file or paste SRT text, choose WebVTT, then click Convert Captions. The tool changes comma timestamps to WebVTT dot timestamps and lets you download a .vtt file.

Are my subtitle files uploaded to a server?

No. The conversion runs in your browser using local file reading, so subtitle text does not need to leave your device.

What is the difference between SRT and WebVTT?

SRT is a simple subtitle format used by many editors and players. WebVTT is designed for HTML video tracks and supports web caption workflows with .vtt files.

Can I fix subtitles that are too early or too late?

Yes. Enter a positive or negative timing offset in milliseconds before converting. Positive values delay captions, while negative values make captions appear earlier.

Can this converter create TTML captions too?

Yes. Select TTML in the output settings to create XML timed text for workflows that require .ttml files instead of WebVTT.
