Converting WAV to AAC produces small, high-quality lossy audio in the codec most streaming services and devices favor. At 160 kbps AAC generally sounds as good as MP3 at 192 kbps, and at 256 kbps it's transparent to nearly all listeners.

AAC is lossy. The encoder makes smart decisions about what to discard, so at sensible bitrates the result is hard to distinguish from the source. You're trading a large uncompressed WAV for a file roughly 8–10× smaller, which is a reasonable tradeoff for any non-editing use.
AAC runs on everything current: iOS, macOS, Windows, Android, all browsers, game consoles, and virtually every streaming device. Older pre-2008 hardware without AAC decoders is the only significant gap.
WAV is Microsoft and IBM's uncompressed PCM container. A stereo CD-quality recording takes about 10 MB per minute. Because nothing is thrown away and nothing is compressed, WAV is the universal working format for recording, editing, and mastering in every major DAW.
AAC is the successor the MPEG group designed to replace MP3. At 128 kbps it typically sounds as good as MP3 at 192 kbps. It's the default codec for YouTube audio, iTunes purchases, Apple Music, and nearly every streaming service that isn't using Opus or Vorbis.
Yes, especially below 192 kbps. AAC handles transients, reverb tails, and cymbals with fewer smearing artifacts. Above 256 kbps both codecs are transparent to most ears.
Roughly 160 kbps AAC. The codec is about 20–30% more efficient, so you can drop bitrate by that amount and end up with equivalent perceived quality.

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
