How to split an MP3 file
- Choose your MP3. It opens in your browser and is not uploaded.
- Enter a length in minutes or seconds. Every part will be that long, except possibly the last.
- Check the list of parts, then download them one by one or as a ZIP.
How fixed durations work
SplitMP3 starts a new part every time the length you chose has passed: from 0:00 to the first interval, then to the second, and so on. The remainder at the end is kept as the last part, so nothing is lost.
Example: a 25-minute MP3 split every 10 minutes gives three parts of 10:00, 10:00 and 5:00. You can enter a number of minutes or seconds, or a length such as 10:30.
If the length you enter is as long as the whole file, no split is made and you are asked to choose a shorter one. If you would rather choose how many parts than how long they are, use split MP3 into equal parts.
Good to know
- Cuts snap to the nearest MP3 frame, about 26 milliseconds. Parts are copied, not re-encoded.
- The first fraction of a second after a cut can start with a few milliseconds of silence.
- Tags and cover art are not copied into the parts.
- Files up to 100 MB on desktop and 50 MB on phones. Only MP3 files are supported.
Frequently asked questions
Can I split an MP3 every 10 minutes?
Yes. Enter 10 and choose minutes. A 25-minute file becomes parts of 10, 10 and 5 minutes. You can also choose seconds or type a length like 10:30.
What happens to the last part?
It keeps whatever is left. If less than one second would remain, it is merged into the previous part instead of creating a tiny file.
Are my MP3 files uploaded to a server?
No. SplitMP3 processes your audio in your browser. Your audio file is not uploaded to our servers.
Does splitting reduce audio quality?
SplitMP3 copies the existing MP3 data into new files without re-encoding it, so the sound itself is not recompressed. Cuts snap to the nearest MP3 frame, about 26 milliseconds, and the first fraction of a second after a cut can start with a few milliseconds of silence. Results can vary by source file.
Is there a file size limit?
Files up to 100 MB are supported on desktop browsers and up to 50 MB on phones and tablets. The exact limit that applies to your device is shown if a file is too large.
Other ways to split
- Split MP3 into equal parts when you know how many pieces you want rather than how long they are.
- Split MP3 by timestamps when parts should start at specific chapter times.
- Place cuts manually on the main MP3 splitter, using the waveform.
