Add music to a video — free, no watermark
Adding a track is a one-minute job in havenConverter: choose the music file, decide whether to keep the original sound, set the mix and fades, export. Nothing is uploaded: the file is read from your disk, processed in the browser tab and saved back to your device.
Steps (single clip)
- Drop the video into the studio.
- In Edits → Audio choose “Add music” (mix) or “Replace audio”.
- Pick the music file (MP3, M4A, WAV…), set volumes, add fade in / fade out or ducking.
- Export — the audio is mixed on your device.
Steps (timeline)
For a montage, use the Timeline editor: drop the music onto the audio lane, trim it to the cut, adjust its volume and fades in the clip panel, and export. Waveforms on the lane make beat-matching easy.
Frequently asked questions
- Will the music be trimmed to the video length?
- Yes — the export is as long as the video (or the timeline), and fades keep the ending clean.
- Which music formats work?
- MP3, M4A/AAC, WAV, OGG/Opus and FLAC, subject to your browser’s decoders.
