Frequently asked questions
Is it free? Is there a watermark?
It is free, adds no watermark and needs no sign-up.
"Plays everywhere" or "Fastest": which one should I pick?
"Plays everywhere" re-encodes the video to H.264, which every phone, computer and TV can play. "Fastest" keeps the original video when the MP4 format allows it, so it takes seconds and the quality is unchanged, but HEVC video may not play on older Windows PCs.
