Video translator
This free video translator gives a video subtitles in another language: your browser takes out the sound, the speech is transcribed and translated line by line, and the translated subtitles come back timed to the video, ready to save as SRT or VTT.

- The video stays on your device

How it works
How do you translate a video?
Choose the video and the language its viewers read. The browser takes out the sound and cuts it into short pieces, which are transcribed in the language spoken; each line is then translated and laid out as subtitles with the times of the speech.
- 1
Drop in the video
An MP4, MOV, M4V, MKV, 3GP or WebM file. Only its sound is read; the picture stays on your device.
- 2
Pick the languages
The spoken language is detected, or you can set it; then choose the subtitle language. Up to 30 minutes of each video.
- 3
Download the subtitles
Translated SRT or VTT, timed to the video, plus the subtitles in the original language.
Does it dub the video or add subtitles?
Subtitles. The translator writes the speech out in another language as a subtitle file you add to the video; it doesn’t make a new voice track or change the video itself. That keeps the speaker’s own voice, and viewers can turn the subtitles on in their language.
How are the translated subtitles timed?
By the speech. Each line of the translation keeps the time of the words it translates, and is then laid out as subtitles by the same rules as the subtitle generator: at most 2 lines, each subtitle on screen for 1 to 7 seconds.
- 1
Lines follow the new script
Up to 42 characters a line, 16 in Chinese, Japanese and Korean.
- 2
Long enough to read
A subtitle stays up a moment after the words end, where the speaker pauses.
- 3
Never mid-word
Subtitles and lines break between words, at sentence ends and pauses first.
Which video files can you translate?
Those a browser can open: MP4, MOV, M4V, MKV, 3GP and WebM, from phones, cameras, screen recorders and video editors. Only the sound is read, so a large file translates as fast as a small one of the same length.

FAQ
Questions about translating videos
Is this video translator free?
Yes. Translate 3 videos a day, up to 30 minutes of each, with no account and no watermark. Translated SRT and VTT, the original subtitles and the translated text are all included.
Is my video uploaded?
No. Your browser reads the video on your device and takes out only its sound. Short pieces of the sound go to a cloud AI transcription service, then the transcript’s text to a cloud AI translation service, and each discards what it was sent. The picture is never sent, and NoteOwl stores nothing.
Does it dub the video?
No. It makes subtitles, not a new voice track, and it doesn’t change your video file. Add the subtitle file wherever you publish the video, or burn it in with a video editor.
Can it translate a YouTube link?
No. It works on video files on your device, not on links. For your own YouTube video, download the file from YouTube Studio, translate it here, and upload the subtitles back to the video.
Can it translate a video to English?
Yes. Choose English as the subtitle language and drop in a video in any of the languages listed. The speech is written down in its own language first, then translated into English line by line.
Do I get the subtitles in the original language too?
Yes. Switch the result to Original to see and download the subtitles in the language spoken, with the same timing, so you can publish both.
What if the video already has subtitles?
Then you don’t need to transcribe it again: translate the SRT or VTT file itself with the subtitle translator, which keeps every subtitle’s number and times.
