SRT vs VTT: Which Subtitle Format Should You Use?

SRT and VTT are both common subtitle formats. The best choice depends on where the video will be published and whether you need web-specific caption features.

When to use SRT

SRT is widely supported by video platforms, editing tools, and localization workflows. It is a good default when you need broad compatibility.

SRT files include subtitle order, timing, and text, which makes them simple to edit and exchange.

When to use VTT

VTT is common for web video and supports web caption features. It is often a good fit for HTML5 video players and browser-based publishing.

If your destination specifically asks for WebVTT, export VTT instead of converting from another format later.

Practical recommendation

Use SRT for broad publishing and editing compatibility. Use VTT for web playback. Keep TXT when you need a transcript rather than timed captions.
