Subtitle Generator — SRT & VTT from any audio or video
Upload your recording and download ready-to-use SRT or VTT subtitle files with accurate timestamps. Works in your browser — no software to install.
Subtitles make your videos accessible, watchable on mute and easier to find in search. Writing them by hand takes many times the length of the recording — our subtitle generator does it automatically. Upload an MP3, MP4, WAV, FLAC, WEBM or M4A file, and the speech is transcribed with per-line timestamps and packaged as a standard SRT file, with WebVTT (VTT) available at the click of a button.
SRT works with virtually everything: YouTube, Premiere Pro, DaVinci Resolve, Final Cut, VLC and most social platforms accept it directly. VTT is the native format for HTML5 video players on the web. You get both from the same conversion, so you never have to convert between formats yourself.
Subtitles come with every transcription on the Classic engine — even the free trial without sign-up: upload a file, and the SRT and VTT download buttons appear right next to your transcript. A free account adds more transcription time, speaker detection and a history that keeps your subtitle files available for later.
