Is the MP3 splitter free?
Yes. Splitting an MP3 into parts is completely free, with no signup or watermark.
Does it upload my MP3?
No. The split and ZIP export run locally in your browser, so your file stays on your device and is never uploaded.
Can I split by equal parts or custom ranges?
Yes. The splitter includes both an equal-parts mode and a custom-range mode so you can choose how the file is divided.
How do I get all the segments?
The split result is packaged as a single ZIP containing every MP3 part, so you can download them all at once.
Does it work on mobile?
Yes. Because it runs in the browser, you can split MP3 files on a phone or tablet as well as a desktop.
How do I split an MP3 into multiple files?
Place the split points in milliseconds and export. Each segment becomes its own MP3, re-encoded in your browser with nothing uploaded.
Why are the split points in milliseconds?
Because a track boundary is rarely on a round second. A DJ mix or a lecture recording needs the cut placed on the silence, and two hundred milliseconds either way is audible.
Does splitting reduce the quality?
A little, because each segment is re-encoded. Split once from the original rather than splitting a piece you already split.
Should I use the splitter or the trimmer?
The trimmer if you want one clip out of a long file. The splitter if you want to cut a file into several pieces in one pass.
Will the segments have clean starts and ends?
Only where you place them. Nothing is detected automatically, so listen to the seams: a split placed slightly early clips the first word of the next segment.
