From speech to SRT

Any video your browser can play works. Audio-only files are supported as well.

FAQ

Can I extract subtitles that are already burned into a video?+

No. This tool creates subtitles from the speech. Burned-in text is part of the image and can't be extracted this way.

Is the SRT file free?+

Yes. SRT, VTT and TXT downloads are included in the free plan.
