Where is my video processed?

Everything happens in your browser: transcribing, translating, making the new voice and mixing it into the video. Your video is never uploaded to Drefly's servers.

Which languages can I dub into?

Arabic, Bengali, Dutch, English, French, German, Hindi, Indonesian, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Tamil, Thai, Turkish, Ukrainian, Urdu, Vietnamese and Yoruba. The original video can be in close to a hundred spoken languages.

What happens to the original audio?

Choose Remove to replace the soundtrack with the new voice, or Keep quietly to leave the original soft underneath so music and sound effects stay.

Can I fix the translation?

Yes. After dubbing, every line of the script is shown next to the original speech. Edit any line and select Update voice. Only the voice is made again, so it's quick.

Why does the first dub take longer?

The first time you use a language, your browser downloads the free on-device models for transcribing, translating and speaking it. They're saved, so later dubs start right away.

Does the video quality change?

No. The video picture is copied as it is, without re-encoding. Only the audio track is replaced.

Yes. It's free with no signup, no watermark and no limit on how many videos you dub.
