Frequently asked questions
Is my file uploaded anywhere?
No — this tool runs entirely in your browser using JavaScript/WebAssembly. Your file is never sent to a server.
Is there a file size limit?
Free accounts can process files up to the limit shown on this page; signing up for Pro raises that limit substantially.
Why does this need a modern browser?
This tool runs a real audio engine (FFmpeg, compiled to WebAssembly) inside the page, which needs a browser feature called SharedArrayBuffer to work. Every current version of Chrome, Firefox, Edge, and Safari supports it — if you see a compatibility warning, try updating your browser.
