CloudConverterConvert MP3 to WAV when your audio editor, video editor or hardware needs uncompressed audio. The conversion takes a few seconds for most files.
MP3 vs WAV: what changes
MP3 is a compressed, lossy format designed for small files. WAV stores audio uncompressed, so files are much bigger: roughly 10 MB per minute at CD quality (44.1 kHz, 16-bit stereo). Converting to WAV does not restore detail that MP3 compression removed, but the file will no longer lose quality when you edit and save it.
When to convert MP3 to WAV
Use it before editing in a music or video editor, when a device or software only accepts WAV, or when you want a stable working copy of a track.
Before you convert
A WAV made from an MP3 sounds the same as the MP3, not better. Expect a file several times larger than the MP3 you started with.
Tips for converting MP3 to WAV
If your MP3 is long, think about whether you need all of it. Trim it first in an audio editor, then convert. WAV files take about 10 MB per minute at CD quality, so long recordings become very large.
Convert MP3 to WAV on any device
Open this page on your phone or computer, choose your MP3 and download the WAV. People usually do this on a computer before importing audio into a music or video editor, which is also where the larger WAV file is easier to handle.
Frequently asked questions
Does MP3 to WAV improve sound quality?
No. The audio data MP3 discarded cannot be recovered. WAV only stores what the MP3 already contained, without compressing it further.
Why is my WAV file so large?
WAV is uncompressed. At CD quality, one minute of stereo audio is about 10 MB, so a four-minute song is roughly 40 MB.
Is the WAV file lossless?
The WAV format is lossless, but it contains the audio from your MP3, which was already compressed. Nothing new is added.
Which programs need WAV instead of MP3?
Many music production, video editing and broadcast tools prefer WAV because it is uncompressed and quick to process.
Can I convert the WAV back to MP3 later?
Yes, but it adds another round of compression. Keep your original MP3 as the master.
Is it free to convert MP3 to WAV?
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.
