🔒 Decoding, merging and encoding all run on your device — your music is never uploaded.
Other joiners cap files at 200–500 MB or meter you per month. Here your own computer does the work — no limits.
Free joiners often re-encode at low bitrates and songs come out flat. Choose up to 320 kbps MP3 or lossless WAV.
Workout mixes, podcast episodes, audiobook chapters, sleep playlists — joined into a single clean file with crossfades.
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 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.
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.
