Trim MP3 & Audio Online — Free, Private, With MP3 Export

Cut ringtones, podcast clips, song intros, or voice memos down to the exact seconds you need. Drop in an MP3, WAV, M4A, or FLAC file, pick the start and end points on the waveform, and export the segment as MP3 or lossless WAV — all locally, with no upload and no file-size cap from us.

Most "free" audio trimmers re-encode your file on a server, queue it behind other users, and stamp limits on output quality. This one decodes and encodes with your browser's own audio engine and a tiny MP3 encoder — your audio never leaves the device.
