Privacy Policy

MP3 Editor Online processes audio entirely in your web browser. Audio files you open are decoded, edited and exported on your own device. We do not upload, store, or transmit your audio files to any server.

What we don't collect

Because the editor is fully client-side, we don't collect your audio files, file names, or metadata. No account is required and no personal information is gathered to use the editor.

Analytics & storage

The site may use privacy-respecting, cookieless analytics to understand aggregate usage. Your theme preference is stored locally in your browser and never sent anywhere. Audio engine assets (FFmpeg WebAssembly) are loaded from our own servers and cached by your browser for faster repeat visits.

External services

Optional Dropbox imports are handled by Dropbox's own chooser and subject to Dropbox's privacy policy. When you open a file from a URL, that file is fetched directly by your browser.
