An SRT file, timed to the speech

CAPWAV transcribes the audio, groups the words into subtitle lines and gives each line its start and end time, in the standard SRT layout: numbered cues, times like 00:00:01,250 --> 00:00:03,000, then the text.

Correct any word in the editor before you download; the timing stays in step. Downloads are saved as UTF-8, so accents and non-Latin scripts come out right.

Use it anywhere

Upload the SRT to YouTube, Facebook or LinkedIn, import it into a video editor, or keep it as a record of what was said. Need WebVTT for a website player? Download VTT instead, or convert later with the free subtitle converter.

Instagram Reels and TikTok don't take subtitle files: for those, export the video with the captions burned in.

Is the SRT download free?

Yes. SRT, VTT and TXT downloads are free on every plan. Transcription uses your plan's minutes: 2 minutes a month on Free.

Can I convert MP4 to SRT?

Yes. Upload the MP4 and CAPWAV makes the SRT from the speech in it.

Can I upload an audio file?

Not yet: CAPWAV takes video files (MP4, MOV, WebM).

Can I edit an SRT I already have?

CAPWAV makes subtitles from the video's speech; it doesn't open existing SRT files. To shift or retime an SRT you have, use the free subtitle timing fixer.
