Why we’re different

Your audio files never leave your computer. All processing happens inside your browser using WebAssembly.

We don’t store, track, or analyze your files. After you close the tab, everything is gone.

Merge large audio files (1GB, 5GB or even 10GB). No artificial limits because everything runs on your hardware.
