Converting WAV to MP3 is the classic fidelity-for-size trade. A 5-minute song drops from roughly 50 MB to 7 MB at 192 kbps with quality most listeners cannot distinguish from the source, which is why MP3 remained the default for portable music for two decades.

MP3 is lossy; the encoder discards frequency content it predicts you won't notice. At 128 kbps you'll hear it on cymbals and string tails; at 192 kbps most listeners can't tell; at 320 kbps even audiophiles struggle to ABX against the source. Pick bitrate based on the listening context.
MP3 is the single most portable audio format on Earth. Every phone, car stereo, browser, media player, smart speaker, and web platform handles it. There is no device older than 1998 that you're likely to encounter in the wild that can't play MP3.
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.
MP3 is the most widely supported lossy audio format. Encoded in 1993 and still the default on countless devices, it trades some fidelity for dramatically smaller files. At 192 kbps most listeners cannot distinguish it from the source. Anything that plays audio will play MP3.
320 kbps if file size doesn't matter. 192 kbps is an excellent default. Most listeners cannot distinguish it from lossless on consumer gear. 128 kbps is audibly compressed but acceptable for spoken word or demos. Below 96 kbps, pick a different codec.
The patents expired in 2017 and newer codecs like AAC and Opus outperform it. But MP3's ubiquity means it's still the right choice when you need maximum compatibility and don't care about saving a few megabytes.

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.
