You can convert any input AVI file: large (over 100Mb), medium, or small.

If you plan to join the files during the conversion, add them in the order you want them to be in the final MP4 video.

Besides AVI, the converter accepts 500+ popular video and audio formats: WKV, WMV, MP3, AAC, M4A, MOV, FLV, and others.

Click “to MP4”

Now click "to MP4" option at the bottom of the free AVI to MP4 Converter software.

Freemake AVI to MP4 program allows users to add to "Favorites" the supported extensions that they use regularly. If MP4 is your everyday choice for the output multimedia container, click the start sign next to the "to MP4" button to mark it as "Favorite". You can create your personal formats bar out of the video and audio extensions you use to convert data most of all.

Set final MP4 file settings

When you click "to MP4", there will appear a window where you can set final MP4 clip parameters. First of all, choose the media quality that you need. If you want to keep everything "as is" without losing video quality after the conversion, select "Same as source" option. Keep in mind, that you have a video file in a non-HD resolution; you can’t select HD or Full HD quality.

Then you need to choose the video codec: MPEG-4 or h.264. Most ready presets go with the second option. However, if you need strictly MPEG-4 codec, you can change the parameters by creating your own MP4 profile. Use the cogwheel button to open the settings & change video resolution, frame rate, sample rate, bitrate, audio codec, and other settings. If necessary, limit the output video file size, and the software will automatically change & suit all the conversion parameters to that value.

In case you want to upload the ready MP4 movies onto your website & share online, mark the option to generate a ready code for your page.

Optional! After your MP4 movies are ready, you can start watching them on a PC or transfer to a portable gadget. We recommend you to play the converted file in a standard media player on your computer. For example, Windows Media Player or VLC are ideal for most multimedia playback.
