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!
TillieI 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.
PDinSFUsed it for over a year to convert my bank statements to csv files. Great quick app, increased my productivity a lot. Also, amazing support - always helped me quickly!
Agata WierzbickaI'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.
JHA very useful and professional site. The service is easy to use and the administrators are helpful and courteous.
David SheltonIt’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.
Ana SuárezI 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 BeeGreat 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 CalisI 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 HermanFantastic 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.

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.
