WAV · processed privately, never uploaded

This free WAV to MP3 converter compresses heavy uncompressed audio into a small, shareable file, cutting size by roughly 7-10× while letting you pick the bitrate. Everything stays private, nothing is uploaded, and there's no account or watermark.

Why a WAV is too big to send

WAV stores audio uncompressed, so it eats about 10 MB for every minute. A three-minute song lands near 30 MB, and a half-hour interview can push past 300 MB, which is exactly the wrong size for an email attachment or a quick upload. MP3 fixes that. At 192 kbps you're down to roughly 1.4 MB per minute, so that same interview drops under 45 MB. The audio sounds the same to most ears; you've just stripped out data your speakers were never going to reveal. Smaller files also mean less phone storage burned and faster sending over slow connections.

Choosing the right bitrate

The one control here is bitrate, and it's the trade-off between file size and fidelity. Reach for 320 kbps when you're converting music and want something close to transparent, where a careful listener won't pick the MP3 from the original. 192 kbps is the sensible default for general listening; it's the sweet spot most people never notice. Drop to 128 kbps for spoken-word material like podcasts, voice memos, or lectures, where there's no rich instrumentation to preserve and the smaller size is pure upside. Higher isn't always better, it just makes bigger files for content that doesn't benefit.

Keep your original WAV

MP3 is lossy, meaning the compression permanently discards some audio data to shrink the file. That's fine for a finished piece you're sharing, but it's a one-way trip. If you still plan to edit, remaster, or run the audio through effects, hold onto the original WAV and treat the MP3 as an export copy. Re-editing an MP3 and exporting again stacks loss on loss and the quality degrades noticeably. One more thing worth knowing: this converts the full recording at its original volume. It won't trim silence, fade edges, or normalize levels, so do that work in your editor first.

Tips

Use 192 kbps as your default; it's the size-to-quality sweet spot most listeners can't distinguish from the source.
For podcasts, interviews, and voice memos, 128 kbps sounds fine and keeps files tiny.
Always archive the original WAV if you might edit again, since MP3 compression can't be undone.
Converting to MP3 is the quickest way to slip a long recording under a mailbox attachment limit.

Questions

How much smaller will my MP3 be?: Expect roughly a 7-10× reduction. WAV runs about 10 MB per minute, while MP3 at 192 kbps is around 1.4 MB per minute, so a 100 MB WAV typically lands near 10-14 MB.
Will I lose sound quality?: MP3 is lossy, so some data is discarded, but at 192 or 320 kbps the difference is inaudible to most people. Keep the WAV original if you'll edit again, since you can't reverse the compression.
Is my file private, or is it uploaded somewhere?: Your file is never uploaded. It's processed privately with no account required and no watermark added, so your audio stays yours.
What bitrate should I choose?: Use 320 kbps for near-transparent music, 192 kbps for everyday listening, and 128 kbps for voice content like podcasts where a smaller file is worth more than extra fidelity.
