CloudConverterConvert WAV to MP3 to make large audio files small enough to email, upload or keep on a phone. MP3 plays on practically every device and app.
WAV vs MP3: what changes
WAV stores audio uncompressed, which is why the files are huge. MP3 uses lossy compression to cut the size dramatically by removing detail that is hard to hear. For listening, sharing and podcasts that is usually the right trade. For editing or archiving, keep the WAV.
When to convert WAV to MP3
Use it for finished songs, voice recordings and podcast episodes you want to share or upload, or whenever a platform has an upload size limit.
Before you convert
MP3 is lossy and the conversion cannot be undone. Keep your original WAV if you might edit or master the audio again.
Tips for converting WAV to MP3
Do your editing, mixing and trimming on the WAV first, and convert to MP3 as the last step. Editing an MP3 and exporting it again stacks compression and lowers quality each time.
Convert WAV to MP3 on any device
Recordings from audio interfaces, editing programs and many voice recorders are saved as WAV. Open this page on a computer or phone, choose the file and download the MP3. WAV files are large, so on mobile data you may prefer to upload over Wi-Fi.
Frequently asked questions
How much smaller will the MP3 be?
Typically a small fraction of the WAV. A 40 MB WAV song often becomes a few megabytes, depending on the audio.
Will I hear the quality loss?
On everyday speakers and earphones most people cannot tell the difference, but the loss is permanent, so keep your original WAV.
How long can the audio be?
The limit is file size, not length: 200 MB per file. A WAV at CD quality uses about 10 MB a minute, so that is roughly 20 minutes of audio.
Will the MP3 work on my phone and car stereo?
Yes. MP3 is supported by virtually all phones, car stereos, speakers and music players.
Can I convert a whole album at once?
This page converts one file at a time. Convert each track separately.
Is it free to convert WAV to MP3?
Yes. It is free, with no sign-up and no watermark.
Are my files kept after conversion?
No. Uploaded files are processed and deleted after your download. We do not keep a library of your files.
Is there a file size limit?
Uploads are capped at 200 MB per file.
