- Review and save. Check Detected format, the cue count and any warnings. Use Copy result or the download button, then try the file with your video.
Questions
Which format do I need?
SRT is widely accepted by players and upload services. WebVTT is used for captions in web video. Choose SBV when your destination asks for it; converting to Plain text removes all timing.
Will styling survive?
Do not expect an exact round trip. ASS/SSA is input-only and loses fonts, positioning and effects. WebVTT style blocks, regions and cue settings are not preserved either. Keep the original if the layout matters.
Do warnings mean the file is unusable?
Not necessarily: two speakers can have overlapping cues on purpose. Backwards timings or an unexpectedly low cue count deserve a closer look. The tool flags some problems but does not repair every cue.
