This tool accepts MP4, MOV, AVI, MKV, WEBM, FLV, WMV, M4V, and 3GP files, depending on your FFmpeg build.
MP4 is usually the best option because it works on most phones, browsers, social platforms, and media players.
PHP cannot convert video codecs by itself. FFmpeg performs the real video decoding, encoding, resizing, and format conversion.
It works only if FFmpeg is installed and PHP exec() is enabled. Many shared hosting providers block exec(), so VPS hosting is better.
