VideoExpander is an AI video expander for uncropping, outpainting, and changing video aspect ratios online. Upload a clip, choose a format like 16:9, 9:16, 1:1, or 4:5, and generate missing edges around the original video. It helps creators turn portrait videos into landscape, zoom out tight shots, resize videos without cropping, and avoid blur borders, stretching, or black bars. Built for creators, editors, marketers, and AI video users.
