How to Bulk Style, Convert, and Position WebVTT Subtitles?
This tool integrates CSS style injection, native SRT to VTT conversion, and timeline vertical adjustments into a single step:
- STYLE Block Injection: Automatically adds the WEBVTT header and your custom CSS rules (such as colors and shadows for
::cuetags). - Optional Vertical Positioning: If enabled, adds or rewrites the
line:XX%directive in each timestamp interval to keep your subtitles exactly where you need them. - SRT Conversion & Cleanup: Transforms legacy
.srtfiles into clean WebVTT format by removing redundant numbering and incompatible intervals.
