SRT to VTT FastConvert is a UXP plugin for Premiere Pro that converts SRT subtitle files into WebVTT (.vtt) format. The conversion takes two clicks: one to choose the SRT file, one to save the VTT. Files are processed entirely on your local machine.
Adobe does not give UXP plugins direct access to caption content on the timeline, so the plugin works from SRT sidecar files you have already exported and generates the matching WebVTT sidecar files from them. During conversion it adjusts timestamp decimal separators from commas to points for standard WebVTT syntax and removes subtitle line numbers.
The plugin runs as a native panel inside Premiere Pro. Version 1.0.0 is compatible with Premiere Pro 25.6.0 or newer and has been tested on Windows 10 and 11.
