Why Subtitles Matter

Most videos are watched on mute. Subtitles keep the message visible and reach viewers in any language.

Captions also help SEO and accessibility — and this tool makes them in minutes, on your own device.

Frequently asked questions

Can I auto-generate subtitles?

Yes. Speech-to-text creates captions from the audio, which you can then edit, re-time, and style.

Can I fix subtitle timing?

Yes. Shift the whole track, sync it to the audio, and edit individual cue times.

What does burn-in mean?

Burn-in draws the subtitles permanently onto the video frames, so they play anywhere — even on players that ignore caption files.
