Part 2. Top 4 Free Sound Converter to Convert Audio Files

Fortunately, the internet is in a plentiful supply of other free to use sound converter app. Here, I'll introduce you to the best websites that convert between popular sound formats without charging you a dime. Better still, most of these sound conversion sites support audio editing. So without much talks, here are your best options:

1. Audio Converter

Well, the name says it all. Audio Converter is a robust website that supports the conversion of multiple sound formats with zero quality loss. In fact, this site allows transcoding of 300+ formats, which I find to be enough for most file conversion tasks. It also supports sound editing by changing the bit rate, sample rate, as well as setting the Fade in/Fade out options. Moreover, you can set the audio quality to Economy, Standard, Good, and Best. More importantly, it converts sound to device-optimized presets like iPhone Ringtone. But sadly, it features some ads.


  • Clean UI.
  • Supports device-optimized presets.
  • Easy to load up.


  • Ad-laden interface.
  • Limited target presets.

2. Online-Convert

If you think that you've already found an online sound converter in the first two options, wait till you use Online-Convert. This music converter comes with a minimalistic UI with it's typical green and white background. Here, file conversion buffs will enjoy unlimited conversion of sound formats like FLAC, MP3, AAC, AU, and more. It can also edit sound settings like bit rate, sampling rate, audio channels, and more. Unfortunately, this free app features some Google ads. Also, it limits your conversion to 100MB only.


  • Nice, clean interface.
  • Simple to understand.
  • Supports sound editing.


  • Ads on the interface.
  • Small upload size.

It also has an upload limit of 100MB per day. But again, Convertio is a beautiful free sound converter to have.
