Best mp3 to wav converter for offline use on Windows 11

There are many free tools available when it comes to mp3 to wav conversion. However, you should pay attention to a few things to make the best of it.

MP3 is a lossy format, meaning it discards some data to reduce file size. Converting MP3 to WAV won't restore lost quality; it simply repackages the existing audio into an uncompressed format. Pay attention to the bitrate of the original MP3 (e.g., 128 kbps vs. 320 kbps), as lower bitrates will result in poorer WAV output. Additionally, ensure choose the best MP3 to WAV converter that doesn't apply unnecessary resampling or processing, which could further degrade the sound.

Another key factor is file size and storage. WAV files are uncompressed, so they can be 10 times larger than their MP3 counterparts. If you're converting many files, make sure you have enough disk space. For example, a 5-minute MP3 at 128 kbps (~4.5 MB) might expand to a 50 MB WAV file. If storage is a concern, consider using FLAC instead; it's lossless but more efficient than WAV. 

Finally, watch out for metadata and compatibility. Unlike MP3, WAV files don't always retain metadata (e.g., artist, album, track info) reliably after conversion. If tags are important, use a tool like MP3Tag to re-embed them post-conversion.
