Put a Soundtrack on Any MP4, WebM or MOV Video

Add music to video online for free: put a song or soundtrack on any clip, replace or mix with the original sound, with fade in and out. No watermarks.

What the Tool Can Do

  • Any song over any clip — upload an audio file or pick a track you generated on Homiwork and lay it over your video
  • Replace or mix — swap the original sound for the music, or keep both and blend them together
  • Fade in and out — smooth the start and end of the soundtrack so it doesn't cut in abruptly
  • Loop to fit — a short track can repeat automatically to cover the whole length of the video

How to Add Music to a Video

  1. Add your video — upload a file or pick one of your generations.
  2. Add the music — upload an audio file or choose a track from your library.
  3. Choose whether to replace the original sound or mix it in, and turn on fade if you like.
  4. Press “Add music” — the video with its new soundtrack is saved to your archive.

Put a Soundtrack on Your Video Without an Editor

Music sets the mood of a video: a soundtrack turns silent footage into a reel, backs a slideshow, or replaces noisy background sound with a clean track. Our tool lays the audio over your clip on the server and keeps the picture untouched — the video stream is copied without re-encoding, so it's fast and lossless. Choose to replace the original sound entirely or mix the music under it, add a fade so the track eases in and out, and let a short song loop to fill the whole video. The result keeps the original quality and is saved next to your other clips.

Frequently Asked Questions

Is adding music to a video free?

Yes. New users get starter energy points; one operation costs just a few points depending on the video length.

Can I keep the original sound and add music too?

Yes — choose “mix” to blend the music under the original audio, or “replace” to swap it out completely.

What audio formats can I use?

MP3, WAV, M4A, OGG and other common audio files, plus any track you generated on Homiwork.

What if the song is shorter than the video?

Turn on looping and the track repeats to cover the whole video; otherwise it plays once and the rest stays quiet.
