What are subtitle formats?

Subtitle formats are standardized ways to store timing and text information for video captions. Different video players and platforms support different formats. SRT (SubRip) and WebVTT (Web Video Text Tracks) are two of the most popular subtitle formats used across the web and in video production.

SRT is one of the oldest and most widely supported formats, while WebVTT is a modern web standard designed specifically for HTML5 video. Converting between these formats ensures your subtitles work across different platforms and devices.
