About MP3 Cutter and Audio Trimmer

Cutting an audio file down to a specific section — removing dead air from the start of a recording, isolating one segment from a longer file — works the same conceptually as trimming video, just for audio alone.

Precise trim points matter here specifically, since a fraction of a second in either direction is often noticeable in audio in a way it might not be in video — this tool lets you preview the exact cut point before committing.

Useful for trimming voice memos, isolating a specific clip from a longer recording, or removing silence from the beginning or end of an audio file.

Frequently Asked Questions

How to cut MP3 files?

Choose your MP3, enter the start and end time in seconds, click trim and download the clip. There is no waveform view, so find the timestamps in your player first. The result stays in the same format as the original file.

How to cut an MP3 on iPhone?

Open the page in your iPhone browser, pick the MP3 from Files, enter the start and end seconds and download the trimmed audio. No app is needed. The first use downloads a video engine of about 30MB, which your browser then caches.

How to cut an MP3 file on Windows or Mac?

Open the page in your browser, choose the file, type the start and end seconds you want to keep and download the cut. Nothing needs installing, and the audio is processed locally on your device.

Does trimming reduce audio quality?

No. The tool copies the selected section without re-encoding, so the sound quality and format stay the same as the original. Because it copies audio frames, the cut points may land a fraction of a second away from the exact times you typed.
