Extend Music

This tool makes a song longer so it reaches the exact length you need. Instead of looping the whole track or pasting a copy at the end, it finds natural beats and section boundaries inside the song and repeats the right ones. The longer version still flows, and the beat keeps time across the join.

To use it, open the editor, upload an audio file (MP3 or WAV), and set the target length. The tool builds the extra time from the song's own repeated sections and lands the cuts on the beat. Preview the result, then export the longer file. No signup, no install, free.

A common case: your video or slideshow runs 3:40 but the track ends at 2:55. Extend the song to 3:40 so the music covers the whole thing instead of dropping to silence. The same goes for a stage performance, ceremony, or presentation that needs music to hold for a set number of minutes.

A tip: extend across a part that already repeats, like a chorus or a steady groove, rather than over a one-time fill or a vocal line. Those spots hide the join best, and adding a small amount usually sounds cleaner than doubling the whole track.

The question people ask: does extending lower the quality or slow the song down? No. It doesn't time-stretch or pitch-shift. The audio plays at its original speed, and the added length is built from the song's own sections.
