About

MP3 Editor Online is a free, browser-based audio editor. We built it so anyone can cut, trim, merge and enhance MP3 files quickly — with no installs, no accounts and no uploads.

Why we built it

Most online audio editors either upload your files to a server or lock useful features behind a paywall. We wanted something simpler and more private: a full-featured editor that runs entirely in your browser, so your audio never leaves your device.

What makes it different

Everything happens locally using WebAssembly and the Web Audio API. Files are decoded, edited and exported on your own device, which means no upload limits, no queues and complete privacy. Editing is free and unlimited, with no watermarks, trials or subscriptions.
