How does the MP3 splitter work?

Upload an MP3 file, choose how you want to split it (equal parts, by duration, or at custom timestamps), and click Split. Everything runs inside your browser using WebAssembly, so your file never leaves your device.

Is my audio file uploaded to a server?

No. All processing happens locally in your browser. Your MP3 is never uploaded, stored, or sent to any server, which keeps your files completely private.

Will splitting reduce the audio quality?

No. The splitter uses stream copy, which cuts the file without re-encoding. Each segment keeps the exact same bitrate and quality as the original MP3.

Can I download all the segments at once?

Yes. After splitting, you can download each part individually or use the Download all (ZIP) button to bundle every segment into a single ZIP archive.

Lossless Cuts

Segments are created with stream copy, so there is no re-encoding and zero quality loss from the original file.

Split Long Recordings

Use 'By duration' to break long podcasts, lectures, or DJ sets into evenly sized, easy-to-navigate chunks.

Precise Timestamps

Choose 'Timestamps' and enter cut points in mm:ss to slice out exact chapters, songs, or highlights.
