There is no universally "best" website for downloading YouTube videos to AVI because many online downloaders have reliability, security, and copyright concerns. However, if you have permission to download a video, using a trusted video conversion tool is generally the safest approach.
One commonly recommended option is 4K Video Downloader. It is a desktop application that allows users to download videos from supported websites and convert them into various formats. Although AVI is an older video format, downloaded videos can usually be converted to AVI using a video converter if needed.
Another popular tool is HandBrake, a free and open-source video transcoder. You can use it to convert legally obtained video files into different formats. While modern formats such as MP4 are more widely supported and efficient, AVI may still be useful for compatibility with older devices or software.
Before downloading videos from YouTube, it is important to understand that YouTube's terms generally restrict downloading content unless a download option is explicitly provided by YouTube or the content creator. Examples include videos available through authorized offline viewing features or videos that are in the public domain and permitted for reuse.
In practice, if your goal is simply to watch videos offline, modern formats like MP4 are usually a better choice because they offer smaller file sizes and broader compatibility. AVI is primarily beneficial when working with legacy systems or specific editing applications that require it.
In short, rather than relying on online YouTube-to-AVI websites, using reputable software such as 4K Video Downloader for obtaining permitted videos and HandBrake for format conversion is typically the safer and more reliable approach.
