Paste or upload a subtitle file and convert between the three most common formats. Everything runs in your browser: your file never leaves your device.
SRT is the classic subtitle format: it works with YouTube, VLC, Premiere and almost every editing tool. VTT is the web variant used by HTML5 players and platforms like Vimeo. TXT is plain text, useful when you only need the transcript without timestamps (to summarise, translate or paste into a document). This tool converts between the three without sending your file to any server: everything is processed in your browser with JavaScript.
If what you actually need is to generate subtitles from an audio or video file, here are market prices:

SRT (SubRip) is the traditional format with timestamps like 00:00:00,000. VTT (WebVTT) is the modern HTML5 version: same timestamp format but with a WEBVTT header and support for CSS styles and positioning. For YouTube either works; for native web players, VTT is better.
No. Conversion happens 100% in your browser with JavaScript. We do not upload anything, we do not store anything, no signup needed.
We do not enforce a limit, but because everything runs in your browser, very large files (several MB) may take a couple of seconds. Typical SRTs for long audio are just a few KB.
By default no: TXT is plain text. If you want to keep timestamps as a reference, tick the "Include timestamps" option before converting.
The converter tries to be tolerant: it skips extra blank lines and normalises separators. If the format is too broken, it will fail with a clear message.
That is automatic transcription. VOCAP transcribes audio/video to text and exports directly to SRT and VTT. You get 30 minutes free on signup to try it.
