Music visualizer online — turn your song into an MP4
- Free 720p
- No sign-up
- Audio never uploaded
- MP4 · 16:9 & 9:16
In short: Drop in a song and a cover image, choose a visualizer (bars, mirrored spectrum, circle around your artwork, oscilloscope wave or soft glow) and colours, and export an MP4 for YouTube, Spotify Canvas-style loops, TikTok or Instagram. Everything renders on your device, so there is no upload wait and no queue. Free visualizer exports are 720p with no watermark and no sign-up; 1080p, 60 fps and 4K are a one-time pass.
Start from a look
Real frames from this editor. Click one, then drop in your song — every setting stays editable.
How it works
- Upload your track and your cover art or a background photo.
- Pick a visualizer: Bars, Mirror, Circle, Wave or Glow.
- Set two colours, blur/darken the background, toggle the beat pulse.
- Optionally add the title, artist and lyrics.
- Export MP4 in 16:9, 9:16, 1:1 or 4:5.
How the visualizer reads your music
Each frame takes a 2048-sample window of the song, runs an FFT, and groups the result into 64 log-spaced bands from 35 Hz to 16 kHz, so kick drums move the left bars and cymbals the right. Bars rise instantly and fall smoothly, which looks musical rather than jittery. The preview and the exported video use exactly the same numbers.
Visualizer styles
| Style | Looks like | Good for |
|---|---|---|
| Bars | Classic spectrum bars along the bottom | YouTube uploads, beat tapes |
| Mirror | Symmetric bars, bass in the middle | Lyric videos with text above |
| Circle | Radial spectrum around your round cover art | Single releases, lo-fi |
| Wave | Glowing oscilloscope line | Podcasts, ambient, vocals |
| Glow | Soft filled spectrum hill | Chill, piano, cinematic |

FAQ
Is there a free music visualizer with no watermark?
Yes. Visualizer videos export free at 720p with no watermark and no length limit. A $4.90 one-time 24-hour pass adds 1080p and 60 fps; 4K is in the 30-day and lifetime passes.
Can I use my album cover?
Yes. Add an image: it becomes the background (with optional blur and darkening) and, in Circle style, the round artwork in the middle.
How long can the song be?
There is no length limit. Long songs simply take longer to render on your device — roughly 20–40 seconds of render time per minute of 720p video on a recent laptop.
Which browsers work?
Chrome, Edge, Safari 17+ and Firefox 130+ on desktop and recent phones. Export uses the WebCodecs video encoder built into the browser.
