SRT and WebVTT both describe timed text. A format conversion should preserve the actual cue times and words. It is not a transcription correction, a translation or a check that the captions match the recording.
Know what this converter preserves
| Item | Treatment | What to review |
|---|---|---|
| Cue timing | Retained to millisecond precision | Start and end match the exported video |
| Cue text | Preserved as text | Names, figures and meaningful line breaks |
| VTT styling and positioning | Not reproduced as a full styling system | Player appearance after conversion |

Convert on your device
- Open the subtitle converter and choose an SRT or VTT file, or paste its contents.
- Select SRT, WebVTT or plain text as the download format.
- Create the result and inspect the shown text. Plain text intentionally removes timing and numbering.
- Download the file and load it beside the exact video export it belongs to.
When conversion is not enough
If every cue is consistently late, use the timing shifter. If timing drifts progressively after a frame-rate change, review whether a frame-rate retime is appropriate. If only individual cues are wrong, edit those cues instead of moving the whole file.
A subtitle file can be syntactically valid while containing incorrect speech. Review proper names, numbers and technical words against the audio. Keep the original subtitle file so a mistaken conversion or edit can be reversed.
