A single long audio file is not always what you need, sometimes you need several shorter ones. The Audio Splitter on File Tools Online divides one audio file into multiple separate files, whether that is a long recording you want broken into equal chunks or a file you want cut at specific points you choose yourself. Upload your file, set where it should be divided, and download the individual pieces. There is nothing to install and nothing to learn, you upload one file and get back several. It works the same way whether you are splitting a long recording, an mp3 mixtape, or an audiobook file into chapters, and the same process applies whether you end up with two files or a dozen.
Open the Audio Splitter and choose the file you want to divide. Drag and drop it, or select it from your device.
Choose how you want the file divided, whether that is into equal parts or at specific points you set.
Get your finished audio files, ready to use, share, or save individually.

The word "splitter" gets used for a couple of very different things when it comes to audio, so it is worth being clear about which one this is. This tool divides a single audio file into multiple separate audio files, cutting a long recording into shorter pieces. It does not separate vocals from instruments, and it does not isolate individual instruments out of a mixed song. If what you actually want is a vocal or instrumental isolation tool, that is a different kind of tool than this one.
This distinction matters because both uses get called a "music splitter" or "mp3 splitter" in everyday language. If you are trying to break a long file into individual tracks, chapters, or shorter clips, this tool does exactly that. If you are trying to pull the vocals or a single instrument out of a finished song, this tool is not built for that, and it is worth confirming which one you actually need before you upload a file, so you get the result you are looking for on the first try.
Dividing one audio file into several smaller ones comes up in a range of everyday situations, especially with long recordings that would otherwise be awkward to work with as a single file.
There are generally two ways to divide a file: splitting it into a set number of equal-length parts, or splitting it at specific points you choose yourself, such as the gaps between songs on a recorded mix. The exact split options available inside the Audio Splitter's own interface, including how many parts you can create and whether you can set custom split points by hand, are set inside the tool and can change as it is updated. Check the tool directly for the specific options currently available before you upload a file.
Equal-part splitting is usually the faster option when a file just needs to be broken into smaller pieces of roughly the same length, for example to fit under an upload size limit. Custom split points take a little more effort but generally give a cleaner result when the content itself has natural breaks, such as separate songs or chapters.
A single audiobook file, lecture recording, or podcast episode can easily run over an hour, which makes it awkward to navigate on a phone or in a media player that does not remember your exact position. Splitting a long file into separate chapter or segment files makes it much easier to jump to the part you want, resume where you left off, or share just one section without sending the whole recording. This is one of the most common reasons people look for an audio splitter in the first place, and it is often the difference between a file that sits unfinished and one that actually gets listened to.
Splitting an audio file traditionally means installing dedicated splitter software or a freeware program, then learning its interface before you get a usable result. The Audio Splitter 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 split pieces when it finishes. If you were looking for splitter software or an app to download, this gives you a comparable result without adding another program to your device.
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 split the result. This applies regardless of how the original file was recorded or where it came from.
Because the Audio Splitter runs in your browser rather than as installed software, it works the same way on Windows, Mac, Chromebook, Android, and iPhone. There is no separate app to find or install on your phone, so you can split an audio file on whichever device you happen to have it on.

File Tools Online is a collection of free, browser based tools for working with audio, video, PDF, and image files, built for people who need a quick, reliable result without installing software. The Audio Splitter is one part of a larger set of audio tools, so once you have your split files, you can trim, normalize, or convert each one using the other tools in the same toolkit.
A long, unbroken audio file is often harder to use than it needs to be, whether it is a vinyl rip, an audiobook, or a lecture recording. Splitting it into separate pieces takes a single unwieldy file and turns it into something you can actually navigate, share, and use one part at a time.
