This looper runs in your browser, so there's nothing to download or install and no account to create. The "online" part matters when you're on a machine you can't install software on, like a school, library, or work computer, or when you just want to loop one file fast instead of opening a full audio editor. Open the page and add your audio by uploading a file. Audjust finds the cleanest loop points, or you pick the section you want to repeat yourself. Preview the join a few times to check it sounds smooth, then export. It handles common formats like MP3 and WAV. The usual job is turning a song into background music that repeats without an obvious click or gap at the seam, for a stream, a study or focus session, or a video where a jump every few minutes would be distracting. You can also pull a short loop or sample out of a longer track to use elsewhere. One thing worth knowing: loops sound best when the start and end land on a beat or at a natural musical phrase. If a join feels slightly off, nudge the start or end by a small amount and preview again until the transition disappears.
