Your audio never leaves your device
Turn audio into SRT and VTT subtitles, free
Generate timestamped subtitle files from any audio, right in your browser. Export SRT and VTT for your video editor or player. Free, no signup, and your audio never leaves your device.
Free, no signup. First run downloads a model once (about 90 MB for the default), then it is cached. MP3, WAV, M4A, OGG, FLAC. Works best up to about 40 minutes per file.
Subtitles from audio, without an upload
If you have narration, a podcast, an interview, or a recorded talk, you can caption it without sending the file to a subtitle service. MeetingScribe transcribes the audio in your browser and gives you ready-to-use SRT and VTT files with timestamps. Because it runs on your device, nothing is uploaded, which is handy when the content is not public yet.
How to make a subtitle file
- Drop your audio file into the tool above.
- Leave timestamps on and, if you want speaker names on the captions, turn on speaker separation.
- Click Transcribe and let it run on your device.
- Open the Subtitles tab to check the timing, then download the SRT or VTT file.
- Load the file into your video editor or player as a captions track.
Extracting subtitles from a video
This tool works from audio. If you have a video, export or extract its audio track first, for example as an MP3 or WAV, then drop that into the tool. The resulting SRT or VTT lines up with the original video because the timestamps come from the same audio.
Tips for clean captions
A larger model gives more accurate text at the cost of a slower first download. Use the in-page editor to fix any misheard words before you export, since edits carry into the download. For long recordings the browser is most reliable up to about forty minutes per file, so caption long videos in segments and combine the subtitle files in your editor.
Frequently asked questions
- What is the difference between SRT and VTT?
- Both are plain-text subtitle formats with timestamps. SRT is the most widely supported and works in most video editors and players. VTT is used on the web with the HTML5 video track element. This tool exports both, so you can pick whichever your tool needs.
- Are the subtitles timed automatically?
- Yes. The tool produces timestamps for each caption line as it transcribes, so the SRT and VTT files line up with your audio.
- Can the captions show who is speaking?
- Yes. Turn on speaker separation and each line can be prefixed with a speaker label, which you can rename.
- Is my audio uploaded to make subtitles?
- No. Everything runs in your browser on your device. Nothing is uploaded.
