Song Extender Free

This free song extender makes an existing track run longer, up to the exact duration you set. Drop in an MP3 or WAV, type a target length, and it stretches the song by repeating and rejoining whole musical sections, not by slowing it down or fading it out. The result still plays as one continuous piece.

Here's how it works: upload a file, set your target length (say three minutes when the original is two), and the tool detects the beats and section boundaries. It adds material at the natural break points, then you preview the loop seam and export. Everything runs in the browser, free, with no install or account.

This helps when a song is too short for what it has to cover. A 90-second track needs to fill a two-minute slideshow, a dance routine runs longer than the music, or an outro has to hold under closing credits. Instead of an obvious second copy starting over, the extended version keeps going without a visible restart.

One tip: put the loop point inside a steady, repetitive part (a chorus or a beat-driven verse) rather than across a big transition. The more uniform that section is, the harder the join is to hear.

The question most people ask: does this generate new music to pad the length? No. It doesn't invent notes or instruments. It reuses and rejoins the song's own audio to reach the length you set, so the result sounds like the original track, only longer.
