WAV to MP3 Converter

How it works

1. Choose your WAV file, or drop it on the page. You can add several files at once.
2. Choose MP3 quality: a bitrate (128 to 320 kbps; 192 kbps is a common balance) or leave the default.
3. Click Convert. Processing happens on your device and shows progress; you can cancel at any time.
4. Preview the result and download the MP3 file. With several files, download them all as one ZIP.

About WAV to MP3 conversion

WAV (Waveform Audio File Format, RIFF container) suits editing, mastering, sampling and handing audio between programs without quality loss. MP3 (MPEG-1/2 Audio Layer III) suits music libraries, podcasts and sharing when you cannot know what the listener uses.

Going from uncompressed WAV to lossy MP3 trades a small, usually inaudible amount of detail for a much smaller file. Keep the WAV original if you may want to edit or re-encode later.

For a 4-minute track, a typical WAV file is about 42 MB and a typical MP3 file is about 6 MB. Your own result depends on the bitrate and the audio itself.

WAV vs MP3

MP3 support: Plays on virtually every phone, car stereo, TV, browser and media player made in the last 25 years.

WAV support: Opens in every audio editor and operating system. Browsers and phones play it, though not every player shows tags.

Quality and compatibility notes

• MP3: Each re-encode loses a little more detail, and there is no true gapless support without extra tags.
• WAV: Large files: about 10 MB per minute at CD quality. The classic format stops at 4 GB, which RF64 extends.
• MP3 bitrate range: 128 to 320 kbps; 192 kbps is a common balance.
• Tags: MP3 stores ID3v1 and ID3v2 tags, including cover art.
