The sound you need, at the right level
Keep the original and your settings
The editor retains the whole original and the same audio settings. MP4 download processes sound while copying compatible video without re-compressing it.
Adjusting a video’s sound
Too quiet or too loud
Set the volume anywhere from 0 to 400% while you listen. Raise a phone video recorded from far away, or lower one with sudden loud parts. Push it too far and the sound can distort, so check the preview.
Mute and fades
If background noise bothers you, mute the sound and add other music. A few seconds of fade-in and fade-out keep the start and end from cutting off abruptly.
Different for each part: volume and pitch curves
Points on a curve change loudness and pitch over time. Raise only the speech, fade slowly towards the end, or shift the pitch in semitones. Each curve holds up to 64 points.
The picture stays the same
When the video is compatible, saving MP4 processes only the sound without re-compressing the picture, so quality stays and it finishes quickly. Sent to the editor, the original goes in with the same audio settings.
FAQ
Are my files uploaded?
No. Everything happens in this browser. The conversion engine (about 30 MB) downloads once and is reused afterwards.
Can it handle large files?
It works in browser memory, so re-encoding files of several GB or long videos can be slow or fail. Use the desktop app for large videos.
Is it free?
Yes. No limits and no watermark.
