VTT to SRT converter

What SRT cannot carry

SRT is the older and simpler format, so this conversion loses a few things that only exist in WebVTT. That is a property of the target format rather than of this converter, and every honest VTT to SRT tool drops the same things.

• Cue settings. Positioning like align:start or position:10% has no SRT equivalent and is removed, so every line renders wherever the player puts subtitles by default.
• Styling. STYLE blocks, regions and class spans such as <c.loud> are dropped; basic italics, bold and underline are kept.
• Comments. NOTE blocks are removed rather than turned into visible subtitle text.

Speaker labels are kept as text

WebVTT marks who is speaking with a voice span, written <v Ada>. SRT has no equivalent, and most converters throw the name away. This one rewrites it into the line as "Ada:" so the information survives in a form SRT can express.

Where SRT is still the format you need

Editing software is the usual reason: Premiere Pro, DaVinci Resolve and Final Cut all import SRT, and several handle VTT poorly or not at all. Set-top boxes and older media players are another, since many will pick up a matching .srt sitting beside a video file but ignore a .vtt.

Cues are renumbered from 1 on the way out, which matters because VTT files often use text identifiers or none at all, and some SRT parsers reject a file whose first cue is not numbered 1.
