Cut any video frame with all its metadata. Frames can be saved back to the Photo Library, to Files, or Shared. All metadata available in the video (like location, camera information, and time of the video) is saved into the frames file. When you add a frame back into photos, it will sit right next to the original video. The time of the frame is even adjusted to the video time plus the time of the frame itself. Open a video using the Share Extension. From Photos or Files, share a video and choose the FrameCutter extension to cut a frame right there. This is a free app, there are no paywall or subscriptions in any manner. If the app is useful, there is an In-App-Purchase to tip the developer.
