How to trim audio
- Choose an MP3, WAV or M4A file up to 10 minutes long.
- Drag the start and end handles on the waveform, or type the times in.
- Press Play selection to hear it, and Hear the end to check the last few seconds.
- Add a fade in or fade out if the cut starts or stops too suddenly.
- Press Trim audio and download your WAV.
Trim or cut out: two ways to use the audio cutter
Keep it (trim) saves only the part between the handles. Use it to pull a sample, a loop or a ringtone out of a longer track, to cut the silence off a recording, or to shorten a beat for a preview.
Cut it out does the opposite: it removes the part between the handles and joins what’s left. Use it to drop a verse, a mistake or a long intro. The join uses a very short crossfade so it doesn’t click, but it will still sound like a jump unless you cut on the beat. Starting and ending the cut on the same beat of a bar, like two downbeats, usually sounds the most natural.
When to use a fade
Cutting in the middle of a sound makes it start or stop instantly, which can leave a click or feel abrupt. A short fade of 0.1 to 0.5 seconds smooths that out without being noticeable. Longer fades of 3 to 8 seconds are for endings, like fading a beat out for a preview. Leave the fade in off for drum loops and one-shots, since it softens the first hit.

FAQ
How do I trim an audio file?
Choose the file, then drag the two handles on the waveform to the start and end of the part you want. Press Play selection to check it, add a fade if you like, then press Trim audio and download the WAV.
Can I cut a part out of the middle of a song?
Yes. Switch to Cut it out, select the part you don’t want and press Cut out the selection. The two sides are joined with a 10 millisecond crossfade so there’s no click where the cut was.
How do I set the start and end exactly?
Type the times into the Start and End boxes, like 1:23.45 or 83.45, and press Enter. You can also click a handle and nudge it with the arrow keys: a tenth of a second per press, or a whole second with Shift held down.
Does it work on my phone?
Yes. Tap anywhere on the waveform to move the nearest handle there, or drag the handles with your finger. Swiping up and down still scrolls the page.
Which files can I trim, and what do I get back?
MP3, WAV and M4A work everywhere, and most browsers also open FLAC, OGG and AAC. You get a 16-bit WAV back, at the same sample rate the browser opened the file at. Need an MP3? This tool doesn’t make them, since that needs an MP3 encoder browsers don’t include.
Is my audio uploaded?
No. The audio cutter works entirely in your browser, so your file never leaves your device. It’s free, with no sign-up and no watermark.
