Every audio tool. Zero uploads.
Convert, trim, join, boost and remix audio entirely in your browser — free, unlimited, and private by design.
Why Sonvert
Built the opposite way around
Private by architecture
There is no server to upload to. Files are processed by WebAssembly in your browser — verify it in your network tab.
Live, not rendered
Editors respond while you play: drag the speed slider or an EQ band and hear it instantly. Export only when it's right.
Free and unlimited
No daily caps, no watermarks, no accounts, no premium tier. Your device does the work, so nothing needs metering.
Works offline
After your first visit the whole toolkit — engine included — runs in airplane mode. It's an installable app, too.
Convert
Every audio converter, one place
Each pair has its own page with format-specific guidance — all running the same no-upload engine.
Edit
Edit audio, right here
Trim, join, boost, normalize, re-speed, EQ — with live preview, and everything stays on your device.
