Frequently Asked Questions
Is this really free?
Yes. There's no limit on the number of files you can convert, and there's no signup required.
Do you store my audio files?
No. Conversion happens entirely in your browser, so your file never leaves your device or touches a server.
What quality is the output AAC?
Files are encoded at 192kbps by default, which gives a good balance of quality and file size for most uses.
Why is AAC smaller than WAV?
WAV is uncompressed audio, so files are large. AAC compresses the audio, shrinking file size dramatically with minimal audible quality loss.
Will this work on my phone?
Yes, it runs in any modern mobile or desktop browser. Very large files may just take a little longer to process on older devices.
What file type do I get back?
You'll get a standard .aac file that plays in iTunes, most phones, media players, and streaming/upload tools that accept AAC audio.
