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.

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.

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.

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.

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.

MP3 Audio Format

MP3 Converter

MP3 goes by the full name of MPEG Audio Layer-3 and is perhaps the most widely used audio file around today. MP3 is a file format developed by the Moving Pictures Expert Group (MPEG) which uses compression to produce smaller file sizes. The type of compression used means some data is lost, but typically audio playback quality is not obviously impacted, especially when recording files at higher bitrates. Other popular audio formats, such as WAV, can be up to 10 times the size of an equivalent MP3 file. Almost all applications are able to open MP3 files including Windows Media Player and iTunes on macOS. The MP3 file format famously exploded in popularity during the '90s and '00s as music moved online and become digitised.
