FAQ
Are my files uploaded?
No. Conversion runs in your browser. CueConvert does not require an account and does not upload subtitle files for conversion.
Does a batch cost extra?
No. A batch is free, with no account, same as one file. Successes download as one zip. Failures are listed on their own.
Will timing and text stay accurate?
We aim to keep readable text and timing. After convert, use the preview to check cues, then download VTT.
What if Chinese text looks garbled?
We try to detect file encoding automatically. If it still looks wrong, re-save as UTF-8 locally, then drop the file again.
What is SBV?
SBV is YouTube Studio’s caption format. Editors and players more often use SRT; web players often use VTT.
Can I convert VTT back to SBV?
Yes. Use the reverse link below this page when that route is live, or open it from the Tools menu.
