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.

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.

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.

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.

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.

You can convert AVI to MP4 using downloadable software such as VLC Media Player or HandBrake. Alternatively, if you prefer a quick, download-free solution, Zamzar’s online converter converts AVI to MP4 in just a few clicks. Simply, upload your AVI file in step 1, select MP4 in step 2, then click to start your conversion. The converted file can be found on the same page ready for download, once the conversion has been completed.

AVI can be converted to MP4 for free using a media player app like VLC, or using a conversion app like Zamzar. Zamzar’s online converter enables you to convert AVI to MP4 for free using the tool on the site’s homepage. Upload your AVI file in step 1, select MP4 as your ‘Convert To’ option, then start the conversion. Your file will be ready for download from the same page, or you can opt for a link to the converted file to be emailed to you.

AVI files can be played by various programs and applications, including Microsoft Windows Media Player, Apple QuickTime Player, VLC media player, Adobe Premiere Pro and Microsoft Movies. If your device can’t play AVI files, you can use an online converter, such as Zamzar, to convert your AVI file to an alternative playable movie format. Zamzar’s tool is also useful if you want to convert multiple AVI files in one go.

If you’re looking for higher resolution, AVI is a good option. However, the higher quality means the file sizes tend to be much larger, meaning you may need to compress your AVI file if you want to share it or store it on your device. For this reason, some people feel MP4 is a better choice - files tend to have a smaller file size and they can be played with most media players, including those on Apple devices. If you want to convert an AVI file to MP4 format, then the online conversion tool on Zamzar’s website makes this really easy.

On a Mac you can convert AVI to MP4 using QuickTime. Open the application, click the ‘File’ menu and add your AVI file. Once uploaded, click the ‘File’ menu again, select ‘Export’, then choose MP4 as the format you’d like to export the file to. Click ‘Save’, and the file will be converted to MP4. If you’d prefer to use a simpler online conversion solution, Zamzar’s free service works just as well with fewer clicks. It’s also more convenient if you want to convert multiple files.
