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.

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.

David Shelton

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 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, 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.

AVI Video Format

AVI Converter

The AVI file has the full name of Audio Video Interleave File and was created by Microsoft. It was originally created in 1992 and is used to store high quality video and audio in a single file. To do this AVI uses different codecs (ways of encoding the audiovisual data), which can make playback challenging if the underlying codecs required to decode the video or audio are not installed. Having been developed by Microsoft it's unsurprising that AVI files can be easily viewed on Windows Media Player.

Apple QuickTime also has a good record of support for this format too. The main difference between AVI and other video and audio formats is that it uses less compression, so whilst the quality tends to be higher file size is as well. An AVI file tends to use 1-2GB per minute of video.

Just upload your MP4 file, select ‘Convert Now’, and your new AVI video will be ready to download and play.

With these online tools, you usually just have to upload your video and click to convert it, before downloading your AVI file.

Whether AVI is better than MP4 depends on what you are using the file for. MP4 files are smaller, so are easier to share, and they also work on most devices and players. However, while MP4 videos will usually play on Windows Media Player, AVI is the format that was designed for Windows. If you’re using Windows video-editing tools, you may prefer to edit AVI files.

You can easily create AVI video files using an online conversion tool like Zamzar – just upload your MP4 file, click to convert it, and then download your video in the new format.
