For posting well-framed video to the Facebook feed (square) or Stories/Reels (vertical).
Facebook shows video across very different placements — a square 1:1 clip performs well in the feed, while Stories and Reels are vertical 9:16. Posting the wrong shape leaves black bars or awkward cropping. This tool reframes your video to the ratio you need in your browser, with a zoom control to choose which part of the frame to keep. It runs locally, so your footage isn't uploaded, and the export has no watermark and needs no account — important for a clean, professional post. Use it to square up a landscape clip for the feed or go vertical for Stories. Drop in the video, pick 1:1 or 9:16, frame with zoom, and download a ready-to-post result. It's the quick, private way to reformat video for Facebook's placements without a desktop editor or a watermarking online tool.
