What SubtitleTools.space does
SubtitleTools.space is a subtitle-file toolkit. It is not a video editor, transcription service, or AI caption generator. It is built for the moment after you have a subtitle file:
- Convert SRT to VTT for HTML5 web video, or VTT back to SRT for a video editor
- Fix broken timestamps, invalid numbering, and overlapping cues
- Shift all subtitle timing by a fixed offset (resync after a video re-edit)
- Convert frame-rate timing (23.976 → 25 fps, etc.)
- Strip HTML tags and hearing-impaired labels from SRT files
- Convert SRT to or from ASS format
- Extract plain text from an SRT file for transcripts or blog posts
- Convert a YouTube transcript with timestamps to a proper SRT file
- Edit subtitle text online with the SRT editor
All tools run in your browser. Your subtitle files never leave your device.
