What Is SRT?

SRT (SubRip Subtitle) is a widely-used subtitle file format that stores text captions synchronized with video or audio using sequential timecodes. It is the standard format for video subtitling across media players, streaming platforms, and video editing software.

This is used for:

  • Video Accessibility: Adding captions to videos for hearing-impaired viewers or multi-language support.
  • Content Repurposing: Extracting subtitle text for analysis, translation, or search indexing.
  • Application Integration: Converting subtitles into JSON for programmatic manipulation in web and mobile apps.

  2. Convert to JSON: Click the "Convert to JSON" button to parse the subtitles into structured data with index, timing, and text fields.
  3. Copy or download: Use the copy button or download the resulting JSON for integration into your application.
