Questions
Frequently asked questions
Does converting SRT to VTT change the caption text?
No. Valid cue text and line breaks are preserved; only the surrounding subtitle format changes.
Is my SRT file uploaded?
No. Conversion runs locally in your browser.
What happens to invalid cues?
Cues without readable timestamps or caption text are skipped, so review the output before publishing.
