Split Audio
Cut one long file into several: place markers on the waveform, or split evenly, and get every part at once.
MP3, WAV, M4A, FLAC, OGG, Opus, AIFF, WMA, AMR and the sound of most videos. Files stay on your device.
How it works
- Choose an audio file.
- Add markers on the waveform, or choose equal parts or a fixed length.
- Review the list of parts and rename them if needed.
- Download each part, or all of them as a ZIP.
Four ways to choose the split points
At markers lets you place the cuts yourself: double-click the waveform, press M at the playhead, or type exact times in the list of parts. Into equal parts divides the file into N pieces of the same length. Every N seconds or minutes cuts at a fixed interval and leaves whatever remains as a shorter last part. At silence finds the quiet gaps and cuts in the middle of each one.
Whatever you choose, the result is the same editable list of parts. Change a start time, join a part to the one before it, or play any part to check it before you export. Changing the equal-parts or interval settings recalculates the points, so make manual edits last.
Exact or fast
Exact decodes the audio and writes each part as its own file, so every cut lands where you put it. Fast copies the compressed audio without re-encoding when the output stays in the input format (MP3, M4A, FLAC, OGG and Opus). Quality is untouched and it finishes in seconds, but a cut can only land on a whole audio frame, about 26 milliseconds for MP3. The results list shows where each fast part really starts and ends.
Naming and downloading
Parts are named from a pattern: {name} is the original file name, {n} the part number ({n:02} pads it to 01, 02, 03) and {total} the number of parts. The default {name}-{n:02} gives song-01.mp3, song-02.mp3 and so on. You can rename any part before downloading, and download them one by one or all together as a ZIP. Tags and cover art are copied to every part unless you remove them in Output settings.
Parts are kept in memory until you download them, so a very long file split into many parts needs room for all of them. Splitting is limited to 500 parts at a time.
Questions
Does splitting reduce the quality?
Not in Fast mode, which copies the audio as it is. In Exact mode lossy formats such as MP3 are encoded once more at a bitrate close to the original; WAV and FLAC stay lossless.
Can I split by chapters or tracks of an audiobook or a mix?
Yes. Place a marker at the start of each chapter or track, or try At silence if the chapters are separated by a pause. Check each part with its Play button before you export.
What happens to the last part when I split every N minutes?
It holds whatever is left, so it can be shorter than the others. A 10 minute file split every 3 minutes gives parts of 3, 3, 3 and 1 minute.
Is my file uploaded?
No. The file is read and split in your browser and never leaves your device.
