What audio formats can I merge?

You can merge MP3, WAV, OGG, FLAC, AAC, M4A and any other format your browser supports. The output is always WAV (lossless PCM).

Can I add silence between tracks?

Yes. Use the Gap setting to add a configurable silence between each track in seconds.

Is my audio uploaded to a server?

No. All merging is done entirely inside your browser using the Web Audio API. Your files never leave your device.

About This Tool
