Adjust Music

This tool changes how long a song runs so it fits exactly where you need it. Make a track shorter, stretch it to a longer target time, or cut a section out of the middle. It all happens in your browser, free, with nothing to install.

To start, upload an audio file (MP3, WAV, and other common formats work). The tool reads the track and marks the natural beats and section boundaries. Drag to set the length you want or type a target time, preview it, then download the result.

Editing at those boundaries is the whole point: the cut lands on the beat. Shorten a song this way and the remaining parts still flow into each other instead of stopping mid-phrase. Extend one and a section repeats on tempo instead of looping with an audible seam.

Two common jobs people do here: cutting a four-minute song down to the 30 or 60 seconds a reel or ad slot allows, and stretching a short track to cover a full presentation, dance routine, or video. It also works for ringtones and for tightening a long intro or outro.

One tip: place your start and end points near the markers the tool shows. Snapping to them keeps the rhythm intact. If a cut sounds slightly off, nudge it to the nearest marked beat and preview again.

The question most people ask is whether changing the length changes the pitch or speed. It does not. The song stays at its original tempo and key. You are only changing how long it runs by editing where sections begin and end.
