In this article, you’ll find a list of programs and online tools that can convert an AVI video for free without risking your data security.

Free programs may be just fine for infrequent conversions, when you are not sure that a purchase is worth it. That said, it can be difficult to find a free app with the functionality needed and that does not pose a security risk.

You can also convert a video to AVI and back online. An online video converter may be a good choice if you don’t want to install any additional software on your computer or if you’re trying to convert files using a smartphone or tablet. Of course, these apps may have some limitations. But when you lack space on your device or just need to perform a single conversion, it is worth giving an online AVI converter a try.

Try this app if you’re looking for a fast and easy-to-use tool to convert anything: from short clips to entire movies. It supports converting multiple files, can rip DVDs, offers editing functionality, and has no restrictions regarding file size. On the other hand, this AVI video converter adds a watermark to your videos (unless you get the full version).

These apps do convert videos to AVI for free (and convert AVIs to other formats as well), but don’t expect too much from them. The fact that they are free of charge is often balanced with watermarks, slow conversion speed, file size and/or length restrictions, etc. Also, if you have a problem with software you’ve paid for, you can call the support center; free programs usually lack user support.

So, if you need to convert videos, audios, or images often, consider getting a shareware app like Movavi Video Converter. This handy app will pay for itself pretty quickly.
