How do I convert WMA files to AAC?

Upload your WMA files to LetsConvert, choose AAC as the output format, and click Convert. The tool processes each track and preserves container metadata like title and album while re-encoding audio to AAC. Download the resulting .m4a files to your device.

Why should I convert from WMA to AAC instead of keeping WMA?

WMA is a legacy Microsoft codec with native support only on Windows and older media players. AAC is the standard audio format for iPhones, iPads, Android devices, smart TVs, and all modern web browsers. It also provides better sound quality at the same bitrate, making it a practical choice when you need broad compatibility and smaller library sizes.

Does converting WMA to AAC preserve bitrate, metadata, and audio quality?

AAC is a lossy codec, so the conversion re-encodes the audio and cannot add detail that is not in the original WMA. The bitrate is set during encoding; if you convert a 128 kbps WMA to 192 kbps AAC, the file size increases but no extra frequency data is recovered. We preserve ID3-style metadata such as title, artist, album art, and track number, but the actual PCM samples are always mathematically different after re-encoding.
