Which bitrate should I use?

128 kbps for speech and podcasts, 192 kbps for general music, 320 kbps when you want the best MP3 can do (files about 2.4 MB per minute).

Does the conversion lose quality?

Yes, MP3 is lossy. At 192 kbps and above the loss is inaudible to almost everyone in normal listening; keep the WAV as your master.

Can I convert a 2-hour recording?

Yes. Encoding runs at roughly 20–50× real time in a desktop browser.

Why convert WAV to MP3

WAV is the right format for recording and editing, but wrong for sharing: it is too large for email and messaging and too heavy for phones. MP3 at 192–320 kbps preserves what listeners can hear and drops the rest.

Encoding uses the LAME encoder compiled to WebAssembly — the same engine used by Audacity — so quality matches desktop tools. Sample rate and channel layout are preserved; 24-bit and 32-bit float WAVs are handled.

How it works

Drop WAV file onto the box above, click it to browse, or paste from the clipboard.
Adjust the options if you need to — the defaults suit most cases.
Press Convert. The work happens on your device, so speed depends on your computer or phone.
Download the MP3 — individually or all at once.

About the formats

WAV · Waveform Audio · .wav

Uncompressed PCM audio, the studio and archival standard: perfect quality, about 10 MB per minute at CD quality.

WAV is a container; almost all WAVs hold uncompressed 16- or 24-bit PCM.
A 4 GB file-size limit applies to standard WAV; long recordings use RF64 or BWF.
Because nothing is compressed, converting WAV to MP3 is the fastest way to shrink audio 10×.

MP3 · MPEG-1 Audio Layer III · .mp3

The audio format everything can play: cars, phones, old players, websites. Lossy, but at 192–320 kbps close to indistinguishable from CD.

All MP3 patents expired in 2017; the format is now free to use.
128 kbps is the classic “good enough” rate; 320 kbps is the maximum.
MP3 cannot store multichannel surround or lossless audio.
