What is an audio cutter?
An audio cutter is a tool that trims a recording to a chosen start and end time and discards everything outside that range. This one runs entirely in your browser, so the file is decoded and cut on your own device and is never uploaded. Open an MP3, WAV, M4A, OGG or OPUS file, then drag the handles on the waveform or type the start and end in seconds, in steps of one hundredth of a second. The start and end fields accept values up to 3,600 seconds, which is one hour. You can add a fade in and a fade out of up to ten seconds each so the cut does not click. Save the result as a 16-bit WAV for full quality, or as an MP3 encoded at 192 kbps for a smaller file. It is free, needs no account and adds no watermark.

FAQ
Is this audio cutter free?
Yes. The audio cutter is free to use, with no account, no watermark and no trial period. The file is decoded and cut in your browser, so nothing is uploaded and no copy is kept. You do need to own the rights to the audio you process. The other tools on this site work the same way.
Does cutting reduce quality?
Cutting only removes the audio outside your range, but saving can still change quality, depending on the format. WAV stores what the browser decoded as 16-bit PCM, so it keeps full quality and makes a larger file. MP3 is compressed and is encoded at 192 kbps, so it is smaller and loses some detail. If your source is already an MP3, saving WAV avoids a second round of compression.
Can I cut audio on my phone?
Yes. The cutter works in mobile browsers, including Safari on iPhone and Chrome on Android. Open the page, choose a file from your phone, drag the waveform handles or type the start and end in seconds, then save WAV or MP3. Which files open depends on what your browser can decode. The file stays on the phone and is never uploaded.
