Three steps to a video.
Upload your audio
WAV, MP3, or FLAC. Trim to the section you want right in the browser, so there is no separate editor in the loop.
Pick from thirty-odd styles
Spectrum bars, a studio-style analyzer, scrolling waveform, spinning vinyl, a vintage oscilloscope, spectrogram, a 3D chrome orb, your own models, kaleidoscope, or split mode running several at once.
Export it clean
Your browser builds the MP4 on your own machine. Vertical 9:16 for the feed, or full-screen 16:9 for a YouTube upload. Nothing uploaded, nothing queued, and no watermark including on your free export.
What free music visualizers actually cost
Free is a pricing decision, not a gift. It is worth knowing which part of the product paid for it.
The four ways free gets paid for
Every free tool is funding itself somehow, and the method usually shows up in the output:
- A watermark, generally placed where it is hardest to crop, which on a vertical clip means across your artwork.
- A resolution cap, most often 720p, which looks visibly soft next to native 1080p in a feed.
- A monthly subscription after a trial, priced on the assumption you will forget to cancel in the months you do not use it.
- Your uploads, kept on their servers, with terms that are worth actually reading if the material is unreleased.
Why the resolution one matters more than it sounds
A 720p cap seems reasonable until the clip is next to native 1080p content on a phone. Vertical video is already re-compressed by every platform, so starting from a lower resolution compounds: you are handing the platform less to work with before it squashes it further.
For a music post specifically, the visible cost lands on fine detail. Thin waveform lines, spectrum bar edges, and chrome highlights are exactly the elements that smear first.
What is actually charged for here
The free account has no expiry and includes the complete app, unlimited building and previewing, and one export up to 15 seconds. After that, choose credits that never expire, an unlimited Pro subscription, or the one-time Lifetime licence.
Nothing about the output is degraded to sell an upgrade: no watermark, no resolution cap, no queue, at any tier. The genuine limitation is browser support, since rendering locally needs Chrome, Edge, Brave, or Arc on desktop. If you need it on a phone, a cloud tool is the better fit and that is a fair reason to pick one.

| Where it renders | Your machine | Their server |
| Pricing | One free export, then credits or Pro | Monthly, or ad-funded |
| Built for vertical | Landscape only, mostly |
