Music visualizer

Turn a song into a video with bars, a ring, or a wave that move with the music. Free, with no watermark, and nothing is uploaded.

Drop your song

Then pick how it looks and save a video that moves with the sound. Nothing is uploaded.

MP3, M4A, WAV, FLAC, and other audio, or a video with sound.

How to make a music visualizer video

Open an MP3, WAV, M4A, or FLAC, pick a visualizer, and save an MP4 where it moves with the music: bars for the spectrum, a ring around your cover art, a mirrored wave, or a line. Change its color, size, and place, and add a picture or a blurred background. This free audio visualizer runs in your browser, so there's no watermark and the song is never uploaded.

  1. Step 1

    Choose your song
    Pick an MP3, WAV, M4A, or other sound file.

  2. Step 2

    Style the visualizer
    Pick bars, a circle, a wave, or a line, and add a picture.

  3. Step 3

    Download the MP4
    Save a video where it moves with the music.

What to expect

Supported inputs
Songs and other sound files, such as MP3, M4A, WAV, FLAC, and OGG, or a video whose sound you want. Pictures can be PNG, JPEG, or WebP.
What happens
The song is read ahead of time, so the preview shows exactly what the video will. The visualizer moves 30 times a second, in step with the sound, and the picture can pulse on the beat. The video lasts as long as the song.
Limits
One song and one picture per video. A visualizer takes longer to save than a still picture, more so for a long mix. It draws from a file, not live from a microphone.

Questions

Yes, with no watermark and no account. It runs in your browser, so the song isn't uploaded anywhere.

Yes. Keep the 16:9 shape, add your cover art or a photo, and save the MP4. YouTube takes it like any other video.

Here, yes: shapes that move with the sound. It works for songs, podcasts, and voice recordings alike.

Yes. Pick Circle and add the picture. It sits inside the ring, and a blurred copy of it can fill the frame behind.

Yes. Each frame shows the sound it plays over, so the bars jump on the frame each beat starts.
