FAQ

Why convert MP4 to AAC?

AAC files are smaller than WAV and often smaller than MP3 at the same quality. They play natively on Windows PCs, Xbox consoles and many car stereos.

Can I choose a specific bitrate like 192 kbps?

Yes. After the upload, open “Advanced settings” and select any bitrate from 64Kbps to 320 kbps, or leave it on auto for balanced size and quality.

Will converting lower the audio quality?

Choosing a high bitrate (192–320 kbps) keeps the sound very close to the original. Lower bitrates create smaller files but reduce fidelity.

Does AAC work on macOS, iOS or Android?

Most third-party players (VLC, foobar2000, Kodi) on macOS, Linux and Android open AAC. For iPhone/iPad you may need a compatible app or convert to AAC.

Is any DRM added to the exported AAC?

No. The converter produces standard, DRM-free AAC files that you can edit, copy or share without restrictions.

What is the maximum upload size?

Videos up to 100 MB are supported. Files larger than 100 MB cannot be processed.

How secure are my files?

Uploads travel over encrypted HTTPS, are processed in volatile memory and automatically deleted from our servers within minutes of conversion.
