Run free AVI to MP4 Converter and add your AVI videos for file conversion. There are three ways to do it. You can click File –> Add video and select the videos from a folder on your PC, USB stick or cloud drive. The 2nd way is to click the "+Video" blue button. And finally, if you have multiple AVI files for MP4 conversion, you can simply drag-n-drop them to the Freemake video software in batch.

You can convert AVI file of any size: 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” format

Choose "to MP4" at the bottom of Free AVI to MP4 Converter. The format is ideal for mobile devices & streaming websites.

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 star 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 to which you convert data most of all.

Set final MP4 file settings

When you click the "to MP4" output format, there will appear a window where you can set the 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 at the end of the conversion.

One more option for the output video: you may add subtitles downloaded from the Internet. Find the respective option in the main freeware window.

When everything is ready, click the "Convert" button and convert your AVI files to MP4 with the best quality. The file conversion process may take some time depending on your PC capacity.

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.
