What is M4A (MPEG-4 Audio)?

M4A is the container Apple uses for AAC audio. Same codec as AAC, just in a different wrapper. iTunes, Apple Music, and all Apple devices use M4A by default.

What is WAV (Waveform Audio)?

WAV stores audio without any compression, so you get the full unaltered recording. Files are big but they work everywhere and are the standard input for audio editing software.

Are my files private?

Yes. All conversion happens in your browser using WebAssembly. Your audio files never leave your device and aren't uploaded anywhere.

Is there a file size limit?

There's no hard limit, but very large files (over 2 GB total) may be slow or run into browser memory constraints.
