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'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 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.

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.

FLV Video Format

FLV Converter

The FLV file, or Flash Video File, was originally developed by Macromedia, a company who were later acquired by Adobe Systems in 2005. FLV files can be opened using software such as Adobe Flash Player and VLC.

Historically Flash video became the de facto file type for almost all video players in the early days of video on the Internet, thanks to the popularity of YouTube, and also the Flash plugin for web browsers, which ensured widespread support for the format. In later years the popularity of the format waned, not least when Apple made a move to HTML5 as their standard file type for streaming video. Sites wuchg as Hulu, Netflix and YouTube itself followed suit in moving to HTML5 for video playback, and in doing so almost killed off the FLV file format.

The file is similar in construction to the standard Flash file (.SWF) in that it stores the audio and the video in much the same way, and just like the standard Flash file it cannot be viewed on iOS.
