Create the video without sending away the master.
VisualizerWave reads your audio and artwork in the browser. The preview and video export use your own computer, so you do not have to upload an unreleased track to a cloud rendering service.
What “local rendering” actually means
When you choose a file, the browser decodes it on your device and uses it to drive the visualizer. Frames are rendered locally and the finished video is saved from your browser. Your computer supplies the processing power; there is no remote video-render queue.
Make it in three moves.
Open the editor
Use VisualizerWave in a compatible browser. Account and purchase access are separate from your media files.
Select files from your device
Choose a local audio file and optional artwork. Previewing and audio analysis happen on the device you are using.
Save the result locally
Export the video to your device. For longer sets, supported desktop browsers can write the export directly to disk.
Private media has a practical trade-off
Because your computer does the work, export speed and maximum comfortable length depend on its browser, memory, and graphics performance. Test a short segment first, especially for 4K or a long mix. The compatibility check shows which export paths your current device supports.
- No render queue
- Your job does not wait behind uploads from other customers. It runs on your device.
- Portable projects
- You can save a project file with its media and settings for later use. Keep that file somewhere you trust.
- Honest limits
- “Local” describes media processing, not a promise that the website never makes network requests for account, checkout, or site services.
Good questions.
Is my song uploaded for rendering?
No. The music file is processed in your browser, and the video is rendered by your device.
Do I still need an internet connection?
You need to access the web app and any account or purchase flow. Local rendering does not mean the entire website is a permanently offline app.
Why does my computer matter?
Your machine handles the audio decoding, visual frames, and video encoding. A longer or higher-resolution export uses more time and resources.
Make the visual.
Keep the music yours.
One payment, unlimited local exports. No render credits or monthly bill.
