Convert any MP3, WAV, FLAC, OGG or M4A file into an MP4 video with abstract, audio-reactive visuals. No upload, no waiting in a render queue, no subscription — drag the audio in, pick a template, hit export.
Unlike "audio-to-video" tools that pin a static image to an audio track, Xenaxio renders frame-by-frame audio-reactive visuals. Bars pulse, particles burst, waveforms ripple — the video actually represents the sound.
No cloud render queue. Your audio is decoded locally via the Web Audio API, frames are rendered via Canvas 2D and WebGL, and the final MP4 is produced via ffmpeg.wasm — all on your own machine. It is only uploaded when you save or run an AI feature.
Cloud audio-to-video converters typically queue your job and email you a link 5–15 minutes later. Xenaxio renders in real time on your CPU and GPU. A 3-minute track becomes a 1080p MP4 in roughly 3 minutes — same as playback length.
Most online MP3-to-video tools paywall higher resolutions or limit free-tier exports per day. Xenaxio is fully free at 1080p and 1440p, with no daily cap.
MP3, WAV, FLAC, OGG or M4A. The file is decoded locally via the Web Audio API. BPM is estimated automatically. Spectrum preview appears instantly.
Choose from 14 scenes and 300+ templates. Layer multiple, add text overlays, image backgrounds or video footage. Apply post-FX. Customise palette and animation.
Pick aspect ratio (16:9 / 9:16 / 1:1) and resolution (1080p / 1440p). MP4 via ffmpeg.wasm or WebM via MediaRecorder. File ready in real-time.
No. Decoding, analysis and rendering all happen client-side in your browser. Audio is only sent to our servers if you sign in and explicitly save a project.
Practically unlimited. Real-world: a 10-minute track exports in roughly 10 minutes of real time on a modern laptop. Memory pressure scales linearly with duration.
Use one of the 300+ ready-made templates — three clicks and you have a video without any design work. Or pick the Minimal Lines scene for a clean visual that does not distract.
The free tier adds a small Xenaxio mark to exported video. Editor and preview are watermark-free. Pro tier (coming) removes the export watermark.
Open the editor — free, no install, no render queue.
