How It Works
The audio joiner decodes all input files using the WebAssembly engine, combines the audio data with your crossfade and volume settings, and encodes the result into your chosen output format. Because everything runs locally in your browser, there's no file size limit imposed by upload restrictions. The only limit is your device's available memory.
