Extend an image to a wider or taller shape with AI, e.g. a portrait photo to a 16:9 YouTube thumbnail without cropping the subject. Costs 5 CropDen credits per run, refunded if it fails. Needs a CropDen API key. Input: PNG, JPEG or WebP, up to 10 MB and 2048 px on the longest side. Returns a link to the result, valid 7 days. The model redraws the whole frame, so tiny details of the original can change.
Target shape, width:height.
Public https URL of a PNG, JPEG or WebP image.
The image as base64 (a data: URL is fine). Use instead of image_url for local files.
