Frequently Asked Questions
Does converting AAC to MP3 lose quality?
Yes. Since both are lossy formats, converting between them involves re-encoding and some quality loss. Higher bitrates minimize this.
Can I convert iTunes purchased songs?
This depends on whether the files have DRM protection. Most recent iTunes purchases are DRM-free but older ones may not convert.
Why use MP3 instead of keeping AAC?
MP3 has the widest compatibility with all devices, players, and platforms. Use MP3 for universal sharing.
Is my audio file uploaded to a server?
No. All conversion happens in your browser using the Web Audio API. Your files never leave your device.
What bitrate should I use for conversion?
Use 192-320 kbps for best quality. Higher bitrates mean larger files but better audio quality.
Can I convert multiple files at once?
Currently this tool converts one file at a time. Process each file separately for batch conversion.
