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.

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.

I 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 Bee

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.

I 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.

Deborah Herman

Fantastic service! My mom's computer died and she has 1000+ Word Perfect files she wants to keep for some reason. Since Word Perfect is basically dead, I decided to convert all her files. Zamzar's converter was perfect.

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.

MP4 Video Format

MP4 Converter

An MP4, sometimes known as an MPEG4, is a multimedia file that is used to store video or audio data. MP4 files are typically smaller in size than other audio or video file types because MP4 files use a mix of compression technologies. Video and audio compression are usually handled by different codecs (audiovisual encoders). The video part is compressed with MPEG-4, a standard that was developed by Moving Picture Expert Group (MPEG), while the audio is typically compressed using AAC compression.

The explosion in popularity of the MP4 format is largely down to Apple and the iTunes Store, as it is the standard format for almost all of the media downloaded from the store. MP4 files are also typically seen when a video is downloaded from the internet.

MP4 files can normally be opened on your computer using Windows Media Player or QuickTime, and can be opened on mobile devices without the need to download any applications.
