Convert VP4 to MP4, AVI, MOV – Fast VP4 Codec Converter Guide

Manuel Gonzalez
Manuel Gonzalez Originally published Aug 29, 25, updated Dec 16, 25

If you’ve stumbled across a VP4 video file, chances are it comes from early 2000s archives, legacy video platforms, or older digital cameras that used On2 codecs. Unfortunately, VP4 is practically extinct in today’s video landscape. Unlike modern codecs such as H.264, HEVC, or VP9, VP4 is not natively supported by Windows, macOS, iOS, or Android players.

This leads to frustrating scenarios: you double-click on a VP4 video and your media player throws an error, or you try uploading it to YouTube and the platform rejects the file outright. That’s why converting VP4 into a standard format like MP4 (H.264) or MOV (ProRes) is essential for playback, editing, and sharing.
