MP4 to AVI Converter Online Free Unlimited

These four online converters are convenient solutions when people want to convert video formats without any software installation. Some additional options like adjusting the video and audio parameters, rotating and trimming your video, or removing the audio, are also included for users.

However, online services have certain limitations. Though a few online video converters, such as Converter App, claim that they allow you to upload files up to GBs and more, the max size of the uploaded file is restricted within the limits of common sense. Factors like internet speed, http server restrictions (2GB standard limit for upload size), or operating system all can affect the file size you can upload. And a large file on a slow network is the worst possible case. It may take you forever to upload, convert, and download the file.

So, for better conversion performance and fewer restrictions, I recommend that you use an offline video converter. In the next part, I will share a free video converter without limits to convert your large MP4 files to AVI more efficiently. I hope you’ll like it.
