Choose a video
Faces are blurred on this device - not the cloud. Your video is never uploaded. Safari keeps the finished output temporarily in local browser storage until you remove it. Choose a video. Chrome and Edge ask where to save; Safari prepares an MP4 for you to download. It is written progressively to your computer at 720p or less. Keep this tab open and visible until processing finishes, and wait for downloading to finish, then review the video before uploading.
