MP3 is great for saving space and streaming, but it is a lossy format — it discards some audio information to shrink file size. WAV is uncompressed and lossless, which makes it the standard for editing, mastering, sample libraries, and archiving. If you need the cleanest possible audio, WAV is the format to use.
Morphix runs a WebAssembly build of FFmpeg directly in your browser. When you drop an MP3 file in, it decodes the compressed audio and re-encodes it as a PCM WAV file — all locally. There is no server, no upload progress bar, and no waiting in a queue.
Unlike cloud converters, your audio never leaves your device. That means better privacy and no file-size or batch limits imposed by a remote service.
