About This Tool

Why use WAV to MP3?

Compress an uncompressed WAV into an MP3 at 192 kbps. FFmpeg runs in your browser, encoding the audio to roughly a fifteenth of its original size while staying transparent for speech and effectively transparent for music in normal listening conditions.

WAV is the right format for editing and the wrong one for sending. A ten-minute recording is around 100 MB as WAV and about 14 MB as a 192 kbps MP3, which is the difference between an attachment that bounces and one that arrives. MP3 also plays on absolutely everything — every phone, car stereo, podcast host and browser — which is not quite true of newer and technically better formats.

WAV to MP3 FAQs

How much smaller will the MP3 be?

Around a fifteenth of the WAV. A ten-minute stereo recording drops from roughly 100 MB to about 14 MB at 192 kbps.

Is 192 kbps good enough for music?

For normal listening, yes — the difference from the source is not audible on typical equipment. For archiving or mastering, keep the WAV.

Can I get the WAV quality back afterwards?

No. MP3 encoding is lossy and permanent. Always keep your WAV originals as the master copies.

Should I use MP3 or AAC?

AAC sounds slightly better at the same bitrate, but MP3 plays on everything without exception. If universal compatibility matters more than a marginal quality edge, choose MP3.
