Why convert SRT to VTT?
VTT is a practical choice for HTML5 video captions and browser-based players. The SRT source is commonly used for widely supported subtitles with simple timing and text.
What changes during conversion?
Timing is retained where the destination supports it, but styling, positioning and cue metadata can differ between subtitle formats. Keep the original until you have checked the converted file in its destination app.

Processing limits and privacy

Compatibility checklist
- Keep the original source until the output has been verified.
- Open the result in the application or platform where it will be used.
- Check timing, line breaks and styling.
- If decoding fails, try a current browser and a smaller known-good sample.
