Put music
on the moment.

Drop one short video and one music file. Balance the original sound, preview the mix and export an MP4.

Video, music and filenames stay on this device. Nothing is uploaded to RWAVE.

Nothing uploads

Both source files and the finished video remain in browser memory on your device.

Original sound is yours

Keep it at 30%, mute it completely, or choose any balance between the video and music.

Made for short clips

The 90-second limit keeps local browser processing predictable. Desktop Chrome or Edge works best.

Add music without a full video editor

Choose a short MP4, MOV, M4V or WebM video and a local audio file. Preview the balance, choose where the music starts and export a broadly compatible H.264 MP4 with AAC audio.

Why can export take a while?
The browser is encoding the video locally instead of sending it to a server. Keep this tab open until the download begins.

What if the video has no original sound?
RWAVE detects that during export and uses only your music automatically.
