Trim MP3 and other audio files to the exact clip you need — fast, private, no re-upload.
Need just the chorus of a song, a single quote from a podcast, or a ringtone-length snippet? The Audio Cutter lets you load an audio file, listen through it, set a start and end point, and export exactly that section. It works with MP3, M4A, WAV, OGG and other common formats, and because it trims by copying the original audio stream rather than re-encoding, the cut is fast and there is no quality loss.
Unusually for an audio editor, everything runs inside your browser using a WebAssembly build of FFmpeg — the same engine that powers professional audio and video tools. Your file is never uploaded to a server; it is processed locally and handed straight back to you. The first time you trim, the tool downloads its audio engine (about 30MB) and caches it for next time.
