The Best Free Converters to Convert AC3 to WAV and Vice Versa

AC3 (Audio Codec 3) is an audio format that uses lossy compression to minimize the overall size, just like MP4. This Dolby Laboratories-created format is often used in DVDs, video games, and movie theatres. However, most media players don't support the playing of AC3 files. For this reason, you will need to convert AC3 to WAV, which is a clear and lossless format. WAV files usually sound better than AC3, regardless of the kbps. Today, we'll be reviewing the best method to convert WAV to AC3 and vice versa using the best converter tools around. Read on!

Part 1. Online AC3 to WAV converters

If you want to avoid the tedious app download and installation processes, you can use a web-based converter. Luckily, the Internet is not short of supply in this regard. All you need is a desktop or even a smartphone/tablet with an internet connection. Even better, most are absolutely free to use and support conversion of AC3 to many other formats, WAV included. Here're my top picks:

1. Convertio

Convertio is another top-class audio converter with simple operation and works with several formats. It supports the conversion of 300+ formats, including audio, video, document, eBook, and many others. What's more, Convertio features a file editor for setting the aspect ratio, codec, quality, and other settings. But just like other online free converters, Convertio has an audio maximum audio upload size of 100MB, which isn't enough.


  • Supports a myriad of formats.
  • Easy to use.


  • The maximum audio upload size is 100MB.
  • Files are unavailable after 24 hours.

2. FreeFileConvert

Third, on this top five list is FreeFileConvert, which claims to support conversion of over 8000 format combinations. It can easily convert between video, audio, image, document, eBook, presentation, and archive files. You can also download audio files from the Internet by pasting the URL or even import from Dropbox and Google Drive. However, your total upload size per day can't exceed 300MB, which is a slight improvement compared to the other options.


  • Several conversion combinations.
  • It can convert up to five files concurrently.


  • Limited upload size.
  • Useless adverts.

3. CoolUtils

Although not so popular, CoolUtils is still an excellent desktop file conversion app. This file converter is capable of supporting over 1400 formats INCLUDING AC3, AU, MP3, MP4, and plenty of others. With it, converting docs, audio, video, and cad files has never been faster, all thanks to its fast performance and clear UI. The interface buttons are clearly labeled, making it easy to understand and use. On the flip side, CoolUtils offers a 30-day free trial period, after which you'll have to pay for the services. That is quite a disappointment.


  • Fast conversion speed.
  • Supports several formats.


  • Cluttered interface.
  • Not exactly free.

Part 2. How to Convert AC3 to WAV or WAV to AC3 Easily

Despite being free, most online free converters have some severe limitations. For example, you can't convert several AC3 files due to the limited upload size. On top of that, one must have a reliable Internet connection to convert the files quickly and losslessly.

Fortunately, Wondershare UniConverter is a capable alternative. With it, converting AC3 to WAV or WAV to AC3 is easy and quick.
