It plays and the video renders in your browser. Only automatic lyric timing on Pro sends it to a server.
It runs in Chrome, Edge, Firefox and Safari.
A tool that reads the frequencies of your song and turns them into visuals that move with every beat, bass hit and melody, then saves the result as a video. Groovalizer does it in your browser with 2,100+ looks, from fractals to liquid light.
How a song becomes a videoAdd your song, pick a look and choose Vertical 9:16. Make one video of the whole song, or 15, 30 or 60 second clips of the hook, each its own file. Playing every look costs nothing, and a free account downloads the video at 720p with a watermark; a clean one is $4.99 or part of Pro.
Music visualizer for TikTokYes. Groovalizer runs in Chrome, Edge, Firefox and Safari on a computer. Your song plays and the video renders on your own machine, so there is nothing to download and no queue on a server.
Online music visualizerGroovalizer plays any song through 2,100+ generative looks in the browser for free, with fractal, liquid, cosmic and abstract styles that react to the music and no account needed.

Best free music visualizers comparedPicture looks
151 picture looks fold an image through a pattern that moves with the song: your cover art, a photo from the shoot, anything you like. Each one comes with a space photo from Webb or Hubble, so you can see it move before you add yours.
More to make
Paste your lyrics and tap along as the song plays, or let Pro time every word. Pick from 7 animations and 15 fonts over any look. The timed lyrics download free as .lrc or .srt.
Full-screen visuals that follow a mic, a DJ mixer or, in Chrome and Edge, the music playing on your computer. Put them on a projector or a stream and let them run. Free, with no account.
Describe a look in plain words, like gold liquid light that stays calm and warm, and watch it get built on the stage. Then ask for changes until it fits the song.

Under the hood
Groovalizer runs in your browser from start to finish. It reads five audio formats (MP3, WAV, M4A, OGG, AAC), analyses them with the Web Audio API, renders through a WebAssembly build of the projectM engine at 60 fps, and encodes video on your computer in 16:9, 9:16, 1:1 or 4:5, up to 4K on Unlimited. Your track stays on your device for all of it, except automatic lyrics on Pro, which send the song to a speech service to write out and time the words.
The rendering engine: an open-source reimplementation of MilkDrop, licensed LGPL-2.1, compiled to WebAssembly and fetched at runtime.
Every look is a .milk preset, the format Ryan Geiss originally created for Winamp. Two decades of community presets run on the same engine as the looks made here.
An AnalyserNode reads the frequency spectrum of your track every frame. Bass, mid and treble come out of that and move the look, so the visuals follow the music instead of looping.
Rendering happens on your GPU at 60 fps, in the browser. Nothing waits in a queue on a server.
Every frame goes through VideoEncoder, up to 4K, and Mediabunny writes the file. A WAV, MP3 or M4A can go in exactly as you uploaded it, so a WAV stays lossless. Choose Compatible for an .mp4 with AAC at up to 256 kbps. Browsers without WebCodecs (Safari, and Firefox before 155) fall back to MediaRecorder and WebM.
