Convert WAV to MP3

Yes, technically — WAV is uncompressed (every sample stored exactly); MP3 uses lossy compression that throws data away to make the file smaller. At 192 kbps (the default), the loss is inaudible to most listeners on typical speakers and headphones. Audiophiles on revealing equipment can sometimes detect differences in cymbals, reverb tails, and very quiet passages.

Dramatically — typically 90% smaller. A 10-minute WAV at CD quality is roughly 100 MB; the equivalent 192 kbps MP3 is around 12 MB. Lower bitrates (128 kbps) shrink further (~7 MB) at a cost of more audible compression artefacts.

192 kbps is a solid middle ground — clean for music, small for podcasts, indistinguishable from the source for typical listening. Use 128 kbps for spoken-word content (podcasts, audiobooks) where file size matters more than sonic detail. Use 256–320 kbps for music when you want quality close to the source and don't mind a larger file.

Limited. WAV's BWF (Broadcast Wave) chunks for metadata aren't universally read; if your WAV came from a DAW or recorder with embedded tags, they may or may not transfer. The MP3 output supports ID3 tags (title, artist, album, etc.) which you can edit afterward in any music app.

Two main reasons: (a) WAV files are too large to share — emailing or uploading a 100 MB WAV is impractical; MP3 makes it manageable; (b) you want a portable listening copy for phones, streaming devices, or anywhere storage matters. Keep the original WAV as the master if you'll re-edit; use MP3 for the consumption-ready copy.
