How do you change the aspect ratio of an existing image or video?

On Higgsfield: Reframe turns a finished video into 9:16, 1:1, 16:9 and other formats, while Outpaint, Expand Image or AI Image Extender extend an image to a new ratio by adding canvas instead of cropping. Ad Resizer adapts static ads to other placements and ratios, adjusting the layout to keep the product and message in focus.

Without Higgsfield: Pick the aspect ratio before generating, since cropping a horizontal video for a vertical feed can cut off important details, and check framing, captions, product placement and safe areas after each conversion. To extend a finished photo past its edges for a new format, FLUX.2 Pro Outpaint generates the new canvas.

Axis: outpaint the new canvas around the original … reframe and crop
