Most of the time you do not need a whole audio file, just one part of it. The Audio Trimmer on File Tools Online lets you keep exactly the section you want and cut away the rest. Upload your file, set where it should start and end, and download just that piece. There is nothing to install and nothing to learn, you upload a file and get back a shorter one. It works the same way whether you are cutting a clip down to a single moment or trimming a few seconds off the start and end of a longer recording, and the same process applies no matter how long the original file is.
Open the Audio Trimmer and choose the file you want to cut down. Drag and drop it, or select it from your device.
Choose where the section you want to keep begins and ends.
Get just the section you selected, ready to use or share.
Processing usually only takes a moment. Your original upload is not changed, you simply receive a new, shorter file with only the part you chose.
Cut a file down to exactly the section you need, nothing more.
Skip the audio editor, upload your file and download the trimmed result directly.
The trimmer runs in your browser, no desktop software or plugin required.
Trim an audio file from a laptop, desktop, or phone, using nothing more than a web browser.
Your file is processed over HTTPS and automatically deleted from our servers within 30 minutes.
There is no cost to trim an audio file or download the result.
Trimming, cutting, or cropping an audio file all mean the same basic thing here: you pick a start point and an end point, and the tool keeps only the audio between them, discarding everything before and after. The result is one shorter file containing just the section you selected. Unlike splitting a file, trimming does not produce multiple output files, and unlike a fade, it does not change the volume of anything, it simply cuts the file down to the part you want.
This makes trimming one of the simplest audio edits there is, but also one of the most useful, since almost every other kind of audio work starts with getting the right section of a file to begin with.
Cutting a file down to just the part you need comes up constantly, whether you are working with music, voice recordings, or anything in between, and it is usually the very first step before doing anything else with a file.
These three get mixed up because they all involve reshaping an audio file, but each one does something different. Trimming keeps one selected section and throws away the rest, giving you a single shorter file. Splitting does the opposite in a sense, it divides one file into several separate files instead of discarding anything. Fading does not cut anything at all, it only raises or lowers the volume at the start or end of a track.
If you know exactly which part of a file you want to keep and do not need the rest, trimming is the right tool. If you need to break a long file into multiple pieces, use the Audio Splitter instead. If your trimmed clip now starts or stops too abruptly, the Audio Fade In/Out tool can smooth that out afterward. Many projects end up using more than one of these tools in sequence, trimming down to the right section first, then smoothing or dividing the result as needed.
The exact controls for selecting your start and end points, whether that is dragging handles on a waveform, typing exact timestamps, or both, are set inside the Audio Trimmer's own interface and can change as the tool is updated. Check the tool directly for the specific controls currently available. In general, being able to see a waveform makes it easier to line up a cut precisely, especially when you are trying to start or end exactly on a beat or a word.
If precision matters for what you are working on, zooming in as far as the tool allows before setting your final points usually gives a more accurate result than eyeballing it at a normal zoom level.
Cutting an audio file down traditionally means opening a dedicated audio editor and learning its interface just to make a simple cut. The Audio Trimmer on File Tools Online skips that step entirely. There is nothing to download and nothing to install, whether you are on Windows, Mac, Android, or iPhone, you upload your file directly in your browser and download the trimmed result. For a quick, one-off cut, that is generally faster than opening a full editor just to trim a few seconds.
The tool accepts common audio formats such as MP3 and WAV, so in most cases you can upload a file directly without converting it first. If your file is in a less common or older format, run it through the Audio Converter first, then trim the result.
Because the Audio Trimmer runs in your browser rather than as installed software, it works the same way on Windows, Mac, Chromebook, Android, and iPhone. There is nothing tied to one operating system, so you can trim a file on whichever device you happen to have it on.
Trimming keeps only the section of the file between the start and end points you choose, discarding everything before and after.
Trimming keeps one section and discards the rest, giving you a single file. The Audio Splitter divides one file into several separate files instead.
Trimming cuts a file down to a selected section. Audio Fade In/Out does not cut anything, it only smooths the volume at the start or end of a track.
