Formula and explanation

WAV stores decoded samples without MP3 compression, creating a larger file. It cannot reconstruct details previously removed by MP3.

Supported path: MP3 → WAV. Compatibility also depends on the codec contained in each file.

Processing runs with FFmpeg WebAssembly inside this browser. Files are not uploaded to Cifrivo or a third-party service.
