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!


Used 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!

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.


I have been so thankful for Zamzar’s support from the beginning of the Pandemic to the present day. Their service is first rate & their helpfulness is always the best it could be.


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 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.

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

MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.

MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.

WMV Video Format

WMV Converter

The WMV format, or Windows Media Video file format in full, is a type of compressed video container (usually also containing audio) developed by Microsoft. This file type can be played by a variety of video players on both Mac and Windows computers.

Some WMV files may have digital rights management (DRM) protection that prevents users from making unauthorised copies of files purchased in online stores.

Simply upload an MP4 file to the free tool on Zamzar’s website, select WMV and ‘Convert Now’ and then download your new video. You can also convert more than one video at the same time.

However, if you wanted to make changes to the video before converting it, you might prefer to open your MP4 file in a video editor like Wondershare Filmora, and then export the project as a WMV file.

Free online file conversion tools like Zamzar are a quick way to convert MP4 to WMV for free. You can convert video files in real time by just uploading your MP4 file, clicking to convert it to WMV and then downloading the new video. There are also free media players, such as VLC, or editing software, such as Wondershare Filmora, that you can download. However, because Zamzar’s tool is cloud-based, there’s no need to install extra software on your device if you would only be using it to convert video files.

Windows 10 does not have a built-in way to convert MP4 to WMV. However, there are some video editor apps, such as Wondershare Filmora, that you can install for Windows 10 that will let you save to WMV. A free way without installing any extra software is to use the tool on Zamzar’s website. Just upload an MP4 video file to the online tool, select to convert it to WMV and then download your video in the new format.

An easy way of converting MP4 files to Windows video is by using an online conversion tool like Zamzar. Zamzar is free unless you’re converting particularly large files and you can convert files in real time in just a few clicks. Simply upload your MP4 files to the tool on Zamzar’s website, select to convert them to WMV (Windows Media Video), and then download the files when they’re ready.

There are also some video players and editors (e.g. Wondershare Filmora) that will let you convert video files between different formats, but you may need to pay for some of these.

It’s simple to create a WMV file using an online tool like the one on Zamzar’s website. You can convert to WMV from a range of video formats – simply upload your video file, set WMV as the format to convert to, and then click ‘Convert Now’. You can then download your new WMV file.

Another way is to download a video editing programme, such as Adobe Premiere Pro, and use this to export a video to WMV format. However, the advantage with Zamzar’s online tool is that you don’t need to install any extra software.
