What is WMA?

WMA (Windows Media Audio) is a proprietary audio format developed by Microsoft. Once widely used for Windows Media Player and DRM-protected music, it offers competitive compression at low bitrates. WMA files are still common in legacy media libraries and corporate environments.

What is AAC?

AAC (Advanced Audio Coding) is a lossy audio format designed as the successor to MP3. It delivers better sound quality at similar or lower bitrates and is the default format for Apple devices, YouTube, and most streaming platforms. AAC files typically use the .aac or .m4a extension.

Frequently Asked Questions

Is the WMA to AAC converter really free?

Yes. There is no account, no watermark and no limit on the number of files.

Will converting WMA to AAC reduce quality?

Not when both formats support the same codecs: we copy the streams without re-encoding. When a re-encode is needed, quality stays close to the original for everyday use.

How long does it take?

Most files are ready in a few seconds. Long or high-resolution videos take longer, mostly depending on upload speed.

Can I convert a YouTube link?

No. The converter works with files on your device. It does not download from YouTube or other sites.

How to open a WMA file?

Windows Media Player handles WMA natively on any Windows PC. VLC and foobar2000 decode WMA on macOS and Linux without extra codecs. For editing, Audacity imports WMA when the FFmpeg library is installed. To improve compatibility, convert to MP3 or AAC with a tool like FFmpeg or MediaHuman Audio Converter.

How to open a AAC file?

iTunes, Music (macOS/iOS), VLC, and Windows Media Player all handle AAC natively. Most smartphones and Bluetooth speakers decode AAC as their default streaming codec. In the studio, Logic Pro and Adobe Audition import AAC directly. If an older device refuses the file, convert to MP3 with FFmpeg: `ffmpeg -i input.aac -codec:a libmp3lame -q:a 2 output.mp3`.
