You can convert MP4 to AVI (for legacy devices), MOV (for Apple devices), MKV (for high-quality storage), WebM (for web playback), or extract audio to MP3.
Which format should I choose?
Choose AVI for older devices, MOV for Apple ecosystem, MKV for archiving with subtitles, WebM for web embedding, or MP3 if you only need the audio.
