Trim Audio
Cut an audio file down to an exact start time and duration, quickly and precisely.
Pulling a specific segment out of a longer audio file — a favorite snippet from a podcast episode, a ringtone-length clip from a song, or the relevant portion of a longer voice recording — is a quick, focused task that doesn't need a full audio editing application.
This tool cuts your audio to an exact start time and duration using stream copying, which extracts the requested segment from the existing encoded audio data without a full re-encode, making the trim operation fast regardless of the source file's length. As with any stream-copy trim, the exact cut point can shift slightly depending on the audio codec's internal frame structure — for most everyday trimming needs (podcast clips, ringtones, voice memos) this is imperceptible.
Processing happens entirely in your browser using a real ffmpeg engine, so there's no upload and your audio never leaves your device.

- Setting a duration longer than the remaining audio after the start time, which simply trims to the end of the source file.
