MP3 Loop

This tool takes an MP3 and exports a trimmed version that loops cleanly, so when the file reaches the end and restarts, there's no click, gap, or audible seam. It scans the audio for the points where the waveform lines up best, builds the loop around them, and saves the result as an MP3.

To use it, open the page and load your MP3. Let it analyze the file, then check the suggested loop start and end on the timeline. Nudge those points for a shorter or longer loop, listen to the join to confirm it sounds smooth, and export. It runs in your browser, so it's free, needs no signup, and nothing installs. MP3 and WAV both work.

A practical case: you have background music for a video, stream, or game that needs to play on repeat. Trimming it by hand almost always leaves an audible bump where it restarts. Letting the tool match the points fixes that. Producers can pull a clean loop or sample out of a longer track the same way, and the same approach works for a study or focus track you want running continuously.

The best loop points usually sit on a steady part of the track, not over a fill, vocal phrase, or big dynamic change. If a loop sounds slightly off, move the start and end onto a calmer section and the join almost always tightens up.

Does it actually save a looping MP3? It exports an MP3 trimmed to your chosen loop region, so any player set to repeat will loop it without a gap.
