FAQ
Is transparency kept?
MP4 with H.264 has no alpha channel; transparent areas become black. Keep WebM for transparent overlays.
How long does it take?
Usually faster than real time with hardware encoding.
What can you do with a video converter?
Creators convert iPhone MOV clips and screen-recorded WebM files to MP4 before posting to Instagram, TikTok or YouTube; podcasters and students pull MP3 audio from interviews and lectures; developers and support teams turn short screen captures into GIFs for docs and chats; editors rewrap MKV recordings into MP4 so their NLE accepts them; and motion designers convert Animdock WebM exports into whatever format a client or platform needs.
