which tool?
Choosing the right tool
- My web player or HTML5 video needs .vtt captions
- Convert your .srt file with the SRT to VTT Converter. Timestamps and multi-line cues are converted exactly.
- My subtitles are out of sync
- Open the file in the Subtitle Editor and use Shift to move every cue earlier or later, or sync individual cues against your video.
- I need to fix typos in auto-generated captions
- The Subtitle Editor lets you edit each cue's text, split long cues by adding new ones, and export SRT or WebVTT.
- My file shows errors
- Both tools report malformed blocks with line numbers, and the editor highlights cues whose end time isn't after their start time.
