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.

MP4 Video Format

MP4 Converter

An MP4 file is often called an MPEG4 file and it is used to store video and/or audio data. When iTunes launched in 2001 the MP4 file format saw a major boom in use. This is because it is the standard format for the majority of iTunes downloads. As well as iTunes causing a major increase in use, the Internet has also been behind its increased popularity as when a user downloads a video on the Internet it tends to be in the MP4 format. MP4 files are clever in their design in that they combine compression technologies which means they tend to be small in size which is another reason for their popularity.

An MP4 file is often known as a container format because of the way it is structured. MP4 files were the file type of choice for Apple’s iTunes mainly because of how efficient they are. In other words, they were small in size but still retained the quality of the audio and video elements. The reason for this is because the audio compression is handled differently from the video compression with the video compression being done using MPEG-4 whilst the audio compression uses AAC which actually helps to improve the audio quality. The increasing popularity of MP4 files has seen the creation of a number of MP4 players which are designed to play MP4 files.

MP3 Audio Format

MP3 Converter

MP3 files are a part of the public’s lexicon as they’ve been popular now for four decades and in that time have often been the go to audio file format of choice for users. The main reason for this is they are around ten percent of the size of an uncompressed audio file format such as a .WAV. Even though they’re a tenth of the size their quality almost matches that of an uncompressed format and so became increasingly popular when we listened to music on the move and storage was at such a premium.
