Your WAV is re-encoded as AAC and wrapped in an MP4 container, producing an M4A file. It is the same format iPhones use for voice memos, so the result plays natively across Apple devices, and on Android and Windows too.
Compared with the WAV original, expect the file to shrink by around 90 percent with quality that everyday listening will not distinguish from the source.
Interview and lecture recordings exported as WAV become manageable M4A files for archiving on a phone. Musicians send M4A demos because the files are small but clean. Audiobook and podcast drafts travel well as M4A since chapters, tags, and cover art are supported by the container.
If the recording is irreplaceable and you want a perfect archive, store a FLAC copy as well: it is lossless at about half the WAV size.

Generally yes. AAC, the codec inside M4A, was designed as the successor to MP3 and squeezes more quality into the same bitrate.
Completely. The conversion runs on your device in the browser. No upload, no server, no copy of your audio anywhere.
