Frequently asked questions

How do I convert an SBV file to TXT?
Drop your .sbv file above. The tool reads the YouTube subtitle file in your browser, removes the timestamp rows, and gives you clean text you can copy or download as .txt.
What is an SBV file?
SBV is a subtitle format used by YouTube. Each cue has a start and end time, followed by the caption text. This converter removes the timing lines and keeps the words.
Does it output one line per subtitle?
Yes. This page is intentionally simple: it outputs clean text line by line, in the same order as the SBV captions.
Are my subtitle files uploaded?
No. The SBV to TXT conversion is pure client-side JavaScript. Your subtitle file stays on your device and is never sent to Captioner or anyone else.
Does it work with non-English subtitles?
Yes. Files are handled as UTF-8, so Chinese, Cantonese, Japanese, Korean, accents, emoji, and mixed-language captions are preserved.
Can I convert TXT back to SBV?
Plain TXT does not contain timing, so it cannot be converted back to a timed SBV file automatically. To create or edit timed subtitles, use the Captioner editor.
