Online Song Length Changer

This tool changes how long a track runs. You can shorten a song, cut a section out of the middle, or extend it to a longer target time, then set it to an exact number of seconds. It runs in your browser, with nothing to install and no signup.

What makes the new length still sound like real music: instead of a hard cut or an obvious repeated loop, the tool finds the beats and section boundaries and makes its edits there. The result lands on the beat instead of mid-phrase.

To use it, open a song from your device, wait a moment while it analyzes the beats, then type the length you want or drag the timeline handles. Preview the join, nudge it if a transition feels off, and download the result.

A common case is matching a song to a video that has to be an exact length, like a 30-second ad or a 60-second reel, without the audio ending early or cutting off. Others are making a ringtone, or a shorter cut for a presentation or performance.

One tip: edits sound best when you let the tool snap to its detected boundaries instead of forcing a cut at a random spot. If a transition isn't clean, move it to a nearby beat marker.

Does changing the length warp the pitch or speed? No. The song plays at its original tempo and pitch; only the duration changes, because whole sections are added or removed, not stretched.
