Best mp3 to wav converter for offline use on Windows 11

In my own experience, I’ve used LAME to convert MP3 to WAV in the past when I wanted pure, uncompressed audio for editing or mastering. But for casual converting, I usually prefer GUI tools like Aud0city or online converters — way easier, and I don’t have to mess around with commands. Plus, I don’t want to waste space on huge files unless I really need to.

from my experience and what I’ve seen, there are a few downsides you should keep in mind — especially if you're not super comfy with tech stuff:

• WAV files are huge. If your MP3 is, say, 3MB, the WAV version might be 30MB or more. So, your storage could fill up pretty fast, and sharing the files becomes a pain.
• MP3 is compressed, which makes files smaller. WAV is raw audio, so you lose all that compression and get a much bulkier file without any quality improvement. Basically, you’re just making the file bigger without any real benefit unless you need uncompressed audio for editing or specific use.
• If you’re not comfortable with command-line tools, LAME can be a bit intimidating. You need to know the right commands, and if you mess up, it might give errors or produce files you didn’t expect.
• LAME’s main job is just converting. It doesn’t handle things like editing, trimming, or fixing metadata tags easily. For that, you'd need other tools.

So yeah, if you’re just converting MP3 to WAV for storage or playback, think about whether you really need the WAV or if the MP3 is enough. But if you’re doing audio editing, then WAV makes sense — just be ready for the bigger files.
