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.
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 CalisGreat 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.
Jiunn-Ru LaiI 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.

WMV Video Format WMV Converter
A WMV file is a video file that was developed by Microsoft. They’re a compressed format, like so many other video formats that had gone before and after, but they still retain excellent quality which is why they’re the file type of choice for Blu-ray disks.

MP4 Video Format MP4 Converter
An MP4 file is a video file that has been compressed in a clever way – with the audio undergoing compression separately from the video. This makes it an efficient file and one that is very popular. MP4 files can be opened by almost any media program, are widely used, and really reached the height of popularity when Apple decided it was its go-to video format.

The easiest way is to use an online conversion tool such as Zamzar. Simply upload the WMV file, select MP4 as the file type you wish to convert to and click “Convert Now”. The file will then be converted in real time without the need to download any software.
It largely depends on what the user needs the file to do. MP4 files are more compatible and more easily opened so if you’re sharing the file then MP4 is probably the way to go. WMV files however tend to be slightly more efficient so if portability isn’t an issue but storage is then the WMV may be the better fit.
WMV files are notoriously difficult to open because they require the correct codecs to be installed on the device that is being used to play them. For example, if the user has a recent version of Windows Media Player then older versions of the WMV file are likely going to need a special codec to be able to get them to play on that newer version of Windows Media Player. Users can either install the codecs that are required or convert the file to a file that is more universally supported such as an MP4 file.
The easiest way is to use Windows Media Player which is still included as part of Windows 10. It may be that the user needs to install some special codecs if their WMV file is particularly old. Failing this, users can use the VideoLAN VLC player which works on any platform or the MPlayer or KMPlayer.
WMV files tend to be opened using Windows Media Player but can also be played using the VideoLAN VLC player which is available on almost all OS’s or users can use the MPlayer or KMPlayer. If a user has not got access to any of these then they can convert their WMV file to an MP4 which are more universally supported.
