How to use Subtitle Delay

- Edit cue timing/text, search or apply an offset.
- Download SRT or WebVTT after validating timing.
Example: An offset of +500 ms moves every cue half a second later.
Questions
Are my subtitle files uploaded?
No. Import, cue editing, timing changes and exports run in your browser. Text and filenames never go to analytics.
What can change during conversion?
SRT and WebVTT exports use plain cue timing/text. ASS/SSA import removes styling/position overrides; WebVTT style blocks and regions are not retained. Negative delay clips starts at zero and removes cues ending before zero.
