How to Convert to WAV on Windows & Mac
Updated August 31, 2026
WAV is what editing software, DAWs, and production workflows expect: uncompressed audio that decodes instantly and re-saves without loss. Whatever you're holding, an MP3, an M4A voice memo, a FLAC file, or a video whose soundtrack you need, converting to WAV is the same quick job.
This guide uses ConvertSave, a drag-and-drop converter for Windows and Mac that runs offline on your own computer.
How to convert any audio to WAV
- 1
Drag your files into ConvertSave
Open ConvertSave and drag your audio files into the window. You can drop one file or a whole selection at once. There is no upload step, because the files never leave your computer.
- 2
Choose WAV as the output format
Pick WAV from the format list. ConvertSave shows the formats that make sense for the files you dropped, so WAV is right there.

Click Convert
Hit the Convert button. Each WAV file is saved next to the original, so you don't have to hunt through folders to find your converted files. The originals are left untouched.
Video files work here too: drop in an MP4 or MOV and pick WAV to get its soundtrack as an uncompressed file, ready for editing.
How to convert to WAV for free
The 7-day free trial covers everything. Session recordings and demos are exactly the kind of files you don't want on a stranger's server, so the offline part isn't just a convenience.
Batch converting to WAV
Drag in as many files as you need and convert them in one pass; each WAV lands next to its source. Watch your disk space: WAV runs roughly ten times the size of compressed audio. We've tested batches of up to a thousand files.
What WAV conversion does and doesn't do
Converting from a lossless source (FLAC, or another WAV) gives you a bit-perfect uncompressed copy. Converting from a lossy source (MP3, M4A, AAC, OGG) gives you an uncompressed copy of exactly what that file contained; the quality lost in the original compression doesn't come back. Either way you get a file every editor will accept and that won't degrade further.
Is converting to WAV safe?
The risk with converting your recordings to WAV isn't the conversion itself, it's where the conversion happens. Free converter websites work by uploading your file to someone else's server. You usually can't tell who runs the server, where it is, or how long your file sticks around after the conversion finishes. For personal videos and photos that's a real privacy trade, and it's the reason so many of those sites are covered in aggressive ads.
ConvertSave does the conversion on your own computer. Nothing is uploaded anywhere. You can turn off Wi-Fi entirely and it still works, which is also the easy way to verify the claim. Your original file is never modified, and the converted copy is written right next to it.
Frequently asked questions
Can I get WAV audio out of a video file?
Yes. Drop in an MP4, MOV, MKV, WEBM, or AVI and pick WAV; the soundtrack comes out as an uncompressed audio file.
Does MP3 to WAV improve the sound?
No, and we'd rather tell you straight: the WAV holds exactly the audio the MP3 had. What you gain is editor compatibility and no further loss from here on.
How big are WAV files?
About 10 MB per minute of stereo audio, so roughly ten times a typical MP3.
Do my recordings get uploaded anywhere?
No. ConvertSave converts on your computer and works offline.
Is ConvertSave free?
There's a 7-day free trial with all features unlocked. After that it's $9/month, $60/year, or $129 once for a lifetime license that covers 3 personal devices on Mac and Windows.
