HandBrake AVI to MP4 converter. Convert AVI to MP4.

HandBrake is an offline tool for converting videos from almost any format. It’s compatible with macOS, Windows, and even Linux computers.

Although the interface is way too outdated and looks unattractive, HandBrake is reliable, and therefore, many people still love and use it.

What does HandBrake support?

  • File Containers: .MP4(.M4V) and .MKV

  • Video Encoders: H.265 (x265 and QuickSync), H.264(x264 and QuickSync), H.265 MPEG-4 and MPEG-2, VP8, VP9, and Theora.

  • Audio Encoders: AAC / HE-AAC, MP3, Flac, AC3, or Vorbis

With this AVI to MP4 converter, you’re also able to select a file title or chapter and a range for it. HandBrake supports subtitles (VobSub, Closed Captions CEA-608, SSA, SRT), VFR & CFR. The service enables video preview and provides video filters (Deinterlacing, Decomb, Denoise, Detelecine, Deblock, Grayscale, Cropping, and scaling).

Wondershare Video Converter

Wondershare Video Converter. Convert AVI to MP4 easily online.

Wondershare provides you with various services. Free Video Converter is one of them. It specializes solely in video conversion.

This is an offline solution both for macOS and Windows computers.

FVC is an advanced converter that offers a wide range of options. For example, you can:

  • Convert videos from iPhone to the desired format, or transform a video file into DVD
  • Create GIFs.

  • Edit video metadata.

  • Convert 4K & HD videos

  • Transfer videos to various devices etc.

  • The AVI to MP4 converter has a free and premium version that provides you with more features and a wider list of supported formats.

If we compare a paid and a free version, the first thing is there’s no “super-speed conversion” in the first case. Another drawback is that it contains ads.

In a free version, you can download videos only from YouTube. In a paid one, you can choose among more websites. Subtitles are supported in both versions. If you pay for the app, you’ll be able to convert a video into MP3 and download videos at a higher speed.

Also, you can record videos from Skype, for example, of unlimited duration, whereas in a free one there’s only 1 minute to record.

Any Video Converter

Any Video Converter. Convert AVI to MP4 online.

AVC is another offline solution for video converting. It’s got nice reviews from TechRadar and other sources. And it’s no surprise.

Any Video Converter is free. This AVI to MP4 converter supports both Mac and Windows computers. It converts any video with no limitations and quality loss.

There’s also a paid version called Any Video Converter Ultimate. The price is $59.95. It provides you with more websites to download videos from and a faster speed of conversion. You can also add special effects.

What’s more, you can extract audio from either a video or CD file. Where can you get content from? YouTube, Facebook, VEVO, Vimeo, SoundCloud, Dailymotion, Vimeo, Metacafe, Howcast, Niconico, and other 100+ sites.


FileZigzag AVI to MP4 Converter. Convert AVI to MP4 online.

FileZigzag might be handy for smaller AVI files. This is the online solution for video conversion. It’s pretty simple. However, this AVI to MP4 converter lacks many features since it’s web-based software.

It takes 4 quick steps to convert a video to an MP4 file:

  1. Drag & drop a file into the featured window.

  2. Choose the desired format.

  3. Type your email address to receive a message about your file status.

  4. Click “Convert” and wait for a couple of seconds.

After that, you’ll be able to download a file via the direct link. It will stay there for a couple of days unless you want to delete it from the server. Alternatively, you can upload a file to your cloud storage (Google Docs/Dropbox).

FileZigzag is a good option for those who don’t want to download any software on their machine. Furthermore, it’s straightforward to use. It works just as it has to.

But there’s a pack of drawbacks. First of all — the website’s UI. It contains tons of ads. The next downside is a size limitation — you can’t download a file if it’s more than 100 MB. In most cases, it won’t be enough to convert even a couple of 20-minute TV series.

Convert. Files

Online Converter. Convert files to MP4 format.

One of the most popular online converters out there.

This is just a simple one-page AVI to MP4 converter that only includes the “Convert Files” window. It’s very popular online, but it’s very generic, nonetheless.

When you land on the website, it shows you immediately its supported file formats. Apart from MP4, the list includes FLV, M4V, MOV, MP3, MPEG, WMV, etc.

If you want to convert your AVI to an MP4 file, simply upload it on this website, enter the output format (the input one is AVI by default). After that, click “Convert”.

Like in the previous case with FileZigzag, you can enter an email to get the video. Otherwise, you may instantly follow a direct link to download an MP4 file. Here, you can convert a file which is up to 250

MB. That’s better than FileZigzag, huh?

Online Video Converter by Wondershare

Online AVI to MP4 Converter by Wondershare.

This online service converts audio & video files into various formats. There’s also a Drag & Drop option just like in FileZigzag mentioned above. As you can see, this online converter has a straightforward user interface.

This converter provides you with an original download link for 24 hours since the conversion. But if you go to FAQs, you’ll discover that you can convert up to 100 MB at once. Such video services are good for short videos. Wondershare also has an offline AVI to MP4 converter that we reviewed above if you want to download more data at once.

In conclusion

No problem cannot be solved on the Internet. Converting videos is not an exception. There are many great AVI to MP4 converters both on- and offline.

Anyway, I strongly recommend learning more about a service before using it. Read the reviews attentively, analyze the website whether it looks user-friendly or not, and. Only then, you can try the product yourself.
