Free tool

Audio joiner.

Join songs, voice memos or recordings into one MP3. Put the files in order, add a short gap between them if you like, and download one file. It runs in your browser, so nothing is uploaded.

Drop audio files here, or click to choose MP3, M4A, WAV, OGG, FLAC or videos. Add two or more. They stay on your computer.

This runs in your browser. Your files are never uploaded.

Questions

Good to know.

Is my audio uploaded?

No. The files are joined in this tab with a WebAssembly build of the LAME MP3 encoder, so they never leave your computer.

Can I mix different formats?

Yes. MP3, M4A, WAV, OGG, FLAC and the sound of videos can be joined in one go. They are all saved as one MP3.

Does it change the quality?

Everything is encoded once more as MP3. At 192 kbps or higher it is hard to hear a difference.

Can I fade between files?

Not yet. You can add a short gap of silence between them.

Which browsers work?

Current Chrome, Edge, Safari and Firefox.
