Plain-English, step-by-step tutorials for everyday audio editing — making ringtones, trimming recordings, fading clips, merging tracks and more. Every guide uses the free AudioTrim editor, which runs entirely in your browser, so nothing you open is ever uploaded to a server.
New to editing audio? Each guide below walks through one task from start to finish, with the exact buttons to click, common mistakes to avoid, and a short FAQ. You don't need to install anything or create an account — open a file, follow along, and download the result as MP3 or WAV.

Traditional audio editors are heavy desktop downloads, and most "online" tools quietly upload your files to a server for processing. AudioTrim does everything locally using the Web Audio API built into your browser. That means there's no upload wait, no file-size cap tied to a server, and your audio never leaves your device. The trade-off is simply that very large files depend on your computer's memory rather than a data center — which for typical songs, voice memos and podcast segments is never an issue.
