Frequently asked questions
Does converting MP3 to WAV improve the sound quality?
No. MP3 is lossy, so detail removed when the MP3 was made can't be brought back. The WAV will sound the same as the MP3; it is just uncompressed, so editing programs and devices that need WAV can open it.
Should I choose 16-bit or 24-bit WAV?
16-bit is CD quality and what most apps expect. Choose 24-bit if you will keep editing or mixing the file in a DAW. 32-bit float is for audio software only.
Why is the WAV file so much bigger?
WAV stores every sample uncompressed: about 10 MB per minute for 44.1 kHz stereo 16-bit, roughly ten times a 128 kbps MP3.
Is the sample rate kept?
Yes. By default the WAV uses the MP3's own sample rate (usually 44.1 or 48 kHz). You can also pick 44.1 kHz or 48 kHz yourself.
Can I convert several files at once?
Yes. Choose or drop as many files as you like. They are converted one after another and each gets its own download button.
Are my files uploaded?
No. The conversion runs inside your browser on your own device. Your audio is never sent to a server, so it works with private and unreleased recordings.
Is it really free?
Yes. No sign-up, no watermark, no daily limit. Very long files (over about an hour) may be too big for a phone's memory.
