FAQ
Is this better than converting WAV to MP3?
Yes, at the same bitrate. AAC is the more capable codec and the WAV is a clean first-generation source, so you get more quality per megabyte. Choose MP3 only when something specifically requires it.
Should I pick AAC or M4A?
M4A for anything you will listen to — it is the same audio in a container that supports tags and seeking. Bare .aac suits technical pipelines that want an elementary stream.
What bitrate should I use?
192 kbps for music is generous. For speech, 96 to 128 kbps is comfortable in AAC, where the same rate in MP3 would sound noticeably thin.
How much smaller will the file be?
Roughly a tenth of the WAV at the default bitrate — a 60 MB recording lands near 6 MB.
Should I keep the WAV?
Yes, if it is a master or a recording you may edit again. The AAC is a distribution copy; keeping the uncompressed original means future conversions still start from clean audio.
Is it really free?
Yes — every conversion on this site, with no account, no watermark and no daily cap. The work happens on your own device, so there is no server bill for us to pass on to you.
Do I need to install anything?
No. It runs in any modern browser, on Windows, macOS, Linux, Android and iOS. There is nothing to download and nothing to sign up for, and once the page has loaded it keeps working with the network switched off.
