What is the difference between SRT and VTT?

Both formats store timed subtitle cues. WebVTT uses a WEBVTT header and supports browser-oriented cue syntax, while SRT uses numbered cue blocks and comma-based millisecond timestamps.

Does converting subtitles change the words?

No. Format conversion preserves the subtitle text and timing wherever the source cues are valid. It does not translate or rewrite the dialogue.

Can this tool generate subtitles from a video?

No. A subtitle converter changes an existing subtitle file between SRT and VTT. Speech transcription is a separate task.

Can I fix subtitle errors before downloading?

Yes. Review the reported cue or timestamp errors, edit the source text, and convert again before downloading.

Are subtitle files uploaded for processing?

The converter is designed to parse and convert subtitle text in your browser. Confirm the page network behaviour before relying on it for confidential material.
