I tried it and immediately fell in love! It was so easy to use! After a couple conversions I bought the guys a cup of coffee. A couple more and decided this was too good to abuse! I joined! My life is so much easier!


I had a huge, problematic file to convert that couldn't go through the usual automated conversion process. The Zamzar team responded quickly to my request for help, and they took the extra steps needed to do it manually.


Used it for over a year to convert my bank statements to csv files. Great quick app, increased my productivity a lot. Also, amazing support - always helped me quickly!

I've used this product for years. And customer service is excellent. Just had an issue where I was charged and I didn't agree with the charge and they took care of it, even though they didn't have to.


A very useful and professional site. The service is easy to use and the administrators are helpful and courteous.

It’s my first time using it. I had some complications doing it. I’m not very good at this. But I wrote to the company and I had a lot of help. I’m satisfied with customer service and with the app.

Great for when you need a lot of conversions in a short time. You have directly access and can even put the subscription on for just a month.

Sabina Calis

Great thanks to you all for helping me to get the OLD files converted correctly. 20 years, quite a long time, reviewing the files brings much memory to me. That's the best gift I received last year. Thank you all again.

WMA Audio Format

WMA Converter

A WMA file goes by the full name of a Windows Media Audio file. After the MP3 file saw widespread success, Apple retaliated by creating the AAC file. Keen to not get left behind, Microsoft developed the WMA file in 1999 in response to those two file formats. Unlike the MP3 and AAC formats, the WMA format used lossy compression. This meant that files were small in size but the audio wasn't as high quality as in its raw form, or as high quality as the audio found in MP3 and AAC files.

In recent years, the WMA format has been further developed so that it now supports lossless surround sound, giving it a slight niche, certainly over the other formats mentioned. However, the WMA file is still not as widely used as its two rivals.

Microsoft Windows Media Player can play WMA files, but other programs tend to require the download of additional plugins before being able to play a WMA file.

AAC Audio Format

AAC Converter

The AAC file is also known as an Advanced Audio Coding file and it is an audio format that uses lossy compression. It is the default file format for Apple’s iTunes. In its design it is like the MP3 file in that the data within it has been compressed but crucially the audio quality of the file is effected.

A human ear cannot tell the difference between a raw audio format and the audio contained in an AAC file. It is this reason why AAC is also becoming the defacto file format for audio for many other programs. Apple, for example, prefer the AAC format to the MP3 because even though both are compressed the quality of AAC is better and it’s file size is the same if not smaller than an MP3 file.

AAC is widely supported and can be opened by every device and program that can open an MP3 file.
