Fast Vocal Separation. Free.
Upload any audio file or paste a direct URL — Toosii returns a clean instrumental track and isolated vocals without an account or subscription.
Drag & drop your audio file here
MP3, WAV, M4A, OGG, FLAC, AAC — max 4.3 MB
Why so small? Uploaded files pass through our server in one request, and our hosting platform hard-caps that at ~4.5 MB — it can't be raised. For bigger files, switch to 🔗 Paste URL above and link the audio instead (up to 20 MB) — that path skips the upload limit entirely.
Vocal Separation
A fast local-first separation pipeline keeps working even when an upstream service is unavailable.
File or URL
Upload from your device or paste a direct link to any audio file online.
Two Tracks
Get both the clean instrumental AND the isolated vocal track separately.
No Sign-up
No account needed. Upload, process, and download — that's it.
