Everything runs in your browser, your audio never leaves your device, and you do not need an account to get started. Follow these steps to build a fast, release-ready visualizer with built-in video backgrounds in a few minutes.
Use the Choose File picker in Upload Audio File and select your track. Supported formats: MP3, WAV, FLAC, AAC, OGG, M4A. Most tracks load in under a second.
Open the Style dropdown and try different looks: spectrum bars, waveforms, oscilloscope, rings, particles, neon glows, mirror, tunnel, and more. Each responds to your audio's bass, mids, and treble in real time.
Use Background (Image) for wallpapers and image uploads, then open Background (Video) for loops and playlists. Across those two panels you have three main options:
Open the Branding / Overlays panel. Use Add title and Add artist / channel to place your track name and artist text as separate overlays. Drag them to position on the canvas, then adjust font, size, opacity, and colour.
In the Cover art section of that panel, upload your album artwork. It appears as a floating image you can drag, resize, and fade.
In the Export Settings panel, click 🔬 Device Spec Check, then use Run check to run a quick browser benchmark and get recommended export settings. Quality-first is the recommended export route on supported desktop Chrome and Edge setups. Legacy real-time remains the fallback on iPad and Safari today. Then set your canvas size (16:9, 9:16, 1:1, or custom) and click Export Video.
720p stays fully free, free HD exports start with the support watermark on, you get 2 clean HD exports before it locks on, and 4K keeps one free watermarked test export per device before the 10-Day Release Pass takes over. Quality-first can save .webm and, on supported Chrome or Edge browsers, .mp4 using H.264/AAC. Use the Quick 720p, Quick 1080p, or Quick 4K buttons when you want a fast shortcut. For focused release-week jobs like Spotify Canvas, X Exports, Release Pack, and Batch Tracks + Playlists, use the quick-launch card above the Visual Style controls. If you build a video playlist, multi-clip background, or long playlist mix, plan around a safe 30fps output today. The Long Playlist Builder is the beta route for planned YouTube mix videos: it exports one song file per track, then joins those files into one final playlist video.
720p stays fully free, free HD exports start with the support watermark on, you get two clean HD exports before it locks on, and 4K keeps one free watermarked test export per device. A £4.99 10-Day Release Pass removes that export friction, adds release-week tools like Spotify Canvas, X Exports, Release Pack, and Batch Tracks + Playlists, and keeps the workflow private for unreleased tracks.
Add up to 5 video clips on the free lane, with larger playlists available during an active 10-Day Release Pass. Drag to reorder them in the timeline. Great for music video-style backgrounds, with the current safest output route planned around 30fps.
Use Batch Tracks + Playlists when you want one finished YouTube mix or playlist video from multiple songs. It renders each song as a safe segment, then joins the finished song files into one beta output. Use 720p or 1080p / 30fps for the most reliable results.
Use the dedicated Audio / EQ panel for bass, mids, treble, and the newer finish controls like gentle compressor, warmth, bass enhance, and presence.
Save your setup to a .json file. Load it back later — the app will prompt you to re-link your media files by name.
Runs a quick browser benchmark, then recommends the best export resolution and FPS. Takes about 3 seconds.
Add a subtle animated layer on top of everything — starfield, matrix, bokeh, rings — to add depth to your visual.
Save your release defaults locally, then load them into a fresh track so style, layout, built-in backgrounds, and logo setup come back quickly without carrying over the old audio.
No account to try, no installs, no server audio uploads. If you buy the pass, checkout uses your email to send the key.
