- Local browser rendering keeps the uploaded song on the device and produces an MP4 without a queue or watermark.
Field notes
The workflow is organized around a local file upload, style selection, optional cover art or lyrics, and MP4 export. The page accepts six named audio formats, limits files to 100 MB and 10 minutes, and offers square, landscape, and vertical output. Its privacy claim is specific: the song remains on the user’s device while the browser performs the rendering.
