What this tool does

Keep or replace the original sound

Mix the song under the voices and noise of the video, each with its own volume up to 200 %, or replace the sound entirely.

Hear it before you save

The preview plays the video and the song together at the settings you chose, so you can check the timing first.

Start, skip, repeat, fade

Choose where the music starts in the video and where in the song it starts, repeat a short song to the end, and fade in and out over 2 seconds.

Original picture quality

The picture is copied, not re-encoded: no quality loss, and even long videos are done in seconds. The sound is saved as AAC at 192 kbps (Vorbis for WEBM).

No upload, no watermark

The video and the song are processed in your browser and never leave your device. No account, no watermark, no time limit beyond the 400 MB size.

Same length as the video

The result is always exactly as long as your video: a longer song is cut at the end, a shorter one repeats or stops.
