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!
TillieI 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.

David SheltonIt’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.
Ana SuárezI use Zamar whenever I need to convert audio and video files from multiple submitters to 1 uniform file format for Audio and Video Editing. I can do multiple large files in a short amount of time.
Christopher BeeGreat 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 CalisGreat 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.
Jiunn-Ru LaiI feel like Zamzar is an active team member, especially for projects that I work on where I am the workhorse and it saves so much time and frustration. I am spoiled with Zamzar, because they have set the bar for file conversion and customer service very high.

M4A Audio Format M4A Converter
An M4A file format is also called an MPEG-4 audio file, and is an audio file saved in the MPEG-4 standard. It was developed by Apple, largely as a result of the popularity of the MP3 file. An M4A file is the go-to audio format for compressed audio, due to the creation and popularity of iTunes.
M4A files tend to be encoded using an AAC codec and are small in size because they have been compressed - often providing a smaller file-size footprint than an MP3 file format, while mirroring, if not improving, the quality of an MP3 file. As more and more music was consumed on the go via devices such as iPods and smartphones, the need for small file sizes became greater, which is why an M4A file has grown in popularity and importance.
One downside of an M4A file, especially when compared to an MP3 format, is that it can only be opened by iTunes or Windows Media Player version 12 and later. By comparison, an MP3 file is universally supported.

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.
