SRT is simple and widely accepted
SRT files are plain subtitle files with numbered cues, timestamps, and caption text. Many video editors, players, and upload platforms accept SRT because the format is easy to read and edit.
If you only need timing and text, SRT is often enough.
WebVTT supports web-focused features
WebVTT files are common for HTML video and web caption workflows. They can support cue settings and styling features that SRT does not handle in the same way.
For websites and web video players, VTT is often the expected format.
Convert based on where the subtitles will be used
The best format depends on the platform. If a video service asks for SRT, convert to SRT. If a web player asks for VTT, convert to WebVTT.
After conversion, quickly scan the first few cues to make sure line breaks and timing still look right.
- Use SRT for broad compatibility
- Use VTT for web video workflows
- Keep a backup of the original subtitle file
