Join audio without the catch

♾️

No quotas

Other joiners cap files at 200–500 MB or meter you per month. Here your own computer does the work — no limits.

🎚️

You pick the quality

Free joiners often re-encode at low bitrates and songs come out flat. Choose up to 320 kbps MP3 or lossless WAV.

🎧

Mixtapes & playlists

Workout mixes, podcast episodes, audiobook chapters, sleep playlists — joined into a single clean file with crossfades.

Audio joiner FAQ

How do I change the order of the tracks?

Use the ▲ ▼ buttons on each track — the file at the top plays first. The total running time updates as you reorder and as you change the crossfade or gap.

Crossfade or gap — which should I use?

Crossfade for music (one song blends into the next, like a DJ set). Gap for spoken content like audiobook chapters or podcast segments where you want a clean pause.

How long can the merged file be?

Hours — the practical limit is your device's memory, since everything is decoded locally. For multi-hour audiobooks on an older phone, merge in two or three parts.
