Grok Imagine adds smart aspect ratio change

xAI's Grok Imagine now uses natural language to change image aspect ratios without cropping, automatically extending backgrounds for multi-platform posts.

xAI's image generator now offers to modify a photo's aspect ratio (16:9, 9:16, 1:1, 4:5, or named formats like 'Instagram story' or 'cinema landscape') without resorting to traditional cropping. The tool analyzes the scene, then extends or recomposes the missing areas to adapt the composition to the new format, while preserving the coherence of the subject and background. The operation is triggered by a natural language instruction formulated directly within Grok Imagine and executes in a single pass. The use case aims to avoid the pitfalls of automatic resizing (cropped subjects, important elements excluded from the frame, distortions) on content initially framed for a different format than required, which corresponds to the common constraints of multi-platform publications: vertical story, square post, horizontal thumbnail, landscape banner.
