## Overview (en)

The subtitle SRT VTT converter turns pasted SRT cues into WebVTT, or WebVTT cues into SRT, keeping cue text and millisecond timings. When converting to WebVTT it adds the header and keeps supported cue settings such as align and position; converting to SRT drops those settings and renumbers cues. You can copy the result or download subtitles.vtt or subtitles.srt.

## Questions (en)

### What happens to WebVTT positioning when converting to SRT?

SRT has no cue settings, so align, line, position, size and vertical values are omitted from the SRT output. Cue text and timings are kept, and cues are numbered from 1 in order.

### Why does the converter reject my VTT file?

The converter accepts plain cues only. STYLE and REGION blocks, malformed timestamps, cues whose end is not after the start, empty cue text and unsupported or duplicate cue settings all produce an error. NOTE blocks are skipped.

### How many subtitle cues can I convert at once?

A file must contain between 1 and 5,000 cues. Timestamps need minutes and seconds below 60, with a comma before milliseconds in SRT and a period in WebVTT.
