Why convert WMV to MP4?
WMV is a Windows-era format that requires extra codecs or plugins on non-Windows systems. MP4 (H.264) plays natively on every phone, browser, and video editor without additional software. Most streaming platforms and editing tools reject WMV outright, so converting once eliminates compatibility issues permanently.
