WAV keeps every detail of the sound with no further compression, which is ideal for editing, mixing, noise cleanup and voice cloning samples.
Most online converters upload your file to their servers. This one does the work locally, so recordings of meetings, interviews or unreleased music never leave your computer or phone.
Yes. iPhone MOV files use the same audio format as MP4, so you can drop them in and get a WAV of the soundtrack.
